Nest #5281

Nickname: Pintail
Nest substrate: Osprey Nest Platform
Nest Location Description: At the south end of Pintail Pond, between the pond and the Tualatin River at Jackson Bottom Wetlands Preserve, 2600 SW Hillsboro Hwy, Hillsboro, OR. Visible from a distance at the north end of Pintail Pond and other points on the preserve. Trail closures were in effect during nesting season in 2014, 2015 and 2016. In 2017 we did not close the trail that goes beneath the nest, thus allowing foot traffic and construction related vehicle traffic. As of the end of May, the pair has shown no ill-reaction to this. 2018 - their is a new nest platform and perch atop a new pole, now located inside Pintail Pond. The pair is building their nest and mating as of the end of March. MAY 31, 2018 - both birds still exhibiting incubation posture when on the nest. We observed behavior one week ago that we thought indicated nestlings but since then we don't have any conclusive observations of chicks in the nest.

First of two nestlings fledged successfully this morning.

05/24/2019 by Jackson
Fairly certain an egg has hatched based on female's behavior in the nest.

Interloper osprey have been a near daily event reported by observers during April. On this date a photographer, Rich Kelly, got photos of two interlopers making a concerted, but ultimately failed, attempt at taking over the nest.

This was the first day we observed clear incubation behavior.

First osprey of the season at Jackson Bottom was sighted on Wednesday, 3/20/19. The bird was flying low from west to east over the Tualatin River and towards Pintail Pond. Weekend reports from the public on 3/23 tell of a pair of Canada geese that took over the nesting platform. The male osprey was being unsuccessful in dislodging the goose and even when the female returned on 3/24, both birds could not dislodge the by now incubating goose. Over the next few days the osprey pair prospected for a new nest site and by 3/29 had settled on a raptor pole a 1/2 mile north between Meadow Mouse Marsh and Wapato Marsh. The pole has two parallel crossbars and it took several days of bringing sticks to the site before they were able to get a foundation that stayed in place. As of April 1 we weren't sure they were going to succeed and we put in place a plan to create a broad foundation atop the crossbars for them. Due to logistics we wouldn't be able to deliver that until April 5. By April 4 it was apparent that the birds were going to be successful in completing their nest without our help, so we left them alone.

Quick report:. Chick #1 has fledged, witnessed 2 tight circles around nest, a quick rest in the ash, and then she escorted both the male and female back to nest to devour fish provided by male. (I strongly suspect chick #1 is female, she is big, broad, heavy dark mottling across breast.) Chicks 2 & 3, both self feeding, also both still fed by mom. #3 still submissive posture at nest. Both #2 & #3 very brief helicoptering at nest, simultaneously, more of a simple hopping with wings out and up, tiny lift. Interloping osprey briefly present, plenty of vocalizing from entire family. Should be a lovely and epic weekend for watching our glorious state raptors! Best, Sonia

Osprey Watch 7-15-18 Sue Nuthmann, Candace Hagen 10:30 am: As we began our watch, the male was on perch in his favorite sentinel tree to the southwest. Female was in the nest with the 3 chicks. How they have grown?! With the naked eye, it looks like we have a whole lot of osprey in that nest. Early on, we have two people join us to view the activity through the scopes. Not too much happening. The female decides to get a little breathing room and removes herself to the perch. One of the chicks, possibly the largest, or number two in order, decides to test out it's landing gear, making pretty strong hopping moves across the nest. Every one of the chicks, up, alert, and looking around. Occasionally, one or more of the chicks is close to the north edge looking over at whatever might be happening on the ground. The water has receded from underneath the nest and most of the activity is closer to the center or other end of the pond. Yet the chicks have their hopes up that they will soon be checking out the basement. Female facing west on the perch. Things stay fairly quiet for the next 45 minutes, no flybys by predators. The chicks are all seen panting. Killdeer activity happening on the west shore of the pond. They are vocalizing quite a bit. There doesn't seem to be much vocalizing by the osprey female or the chicks. Possibly an indication that they have been recently fed before we arrived? 3 egrets and several GBH are hunting along northeast shore or in the water at the north end of pond. A dozen or more Canada Geese with the one gosling who is getting almost as big as the adults, but the markings differ from the adults. The colors are more blurred and the neck plumage blends into the breast more than on the adults where the black of the neck is very dark and has a distinct edge. A northern flicker flies over, earlier, we had heard its drumming in the trees to the southeast. Many crows flying back and forth over the pond, though not the numbers we have seen in weeks past. 11:15: The male osprey moves to a tree to the east, and within a few minutes he has flown off. Around noon, a bald eagle is flying from east to west overhead with a fish in its talons. He is soon being chased by the male osprey who is trying to knock him out of the sky and/or retrieve the fish from him. The eagle leaves in a hurry still with his fish intact. Two people were able to see this display as they headed to the shelter. They are from the Bay area, traveling around to various bird areas on their folding bicycles, and then carrying them onto public transportation to get through the not so scenic areas between the birds. Impressive, talk about dedication to birding and biking! Sue gave them some of our best birding areas to visit. 12:20 Female and chicks start vocalizing, something is getting their attention. The male osprey flies into the perch with a fish, with the head still on. Soon he drops it in the nest and flies off. Female on the south side of nest with the fish. Two of the chicks join her and the littlest chick sits on the north side of the nest with its back to the feeding. It appears the female is taking turns feeding herself and the two largest chicks. A few minutes later the #1 chick is feeding with the female and the second in line chick has its back to the adult and #1 chick. Adult male on the sentinel tree is out on the very tip edge of one of the bare branches. He is looking alert and facing southwest. 12:45: Female has moved to the perch above the nest, She has only her right wing cocked out at an angle as though she is catching air to cool off? She has to have her right foot off the top of the horizontal 2 x 2 she is sitting on. Possibly is grasping it from the other side? We are hoping it is not some kind of injury? #3 chick(the smallest) joins the other two chicks on the south edge of the nest and all three appear to be picking at leftovers? 12:55: Chick #1, the largest, testing wings and landing gear, helicopters for several seconds over the nest. Sue observed two times, i saw only the last one. Very exciting! A few minutes later, not sure if chick #2 or #3, but one starts hopping from one side of nest to the other. Sue thought it was going over the edge. Mother that she is, she kept warning him to "stop, stop, stop". I am thinking it was not listening, it was either having too much fun or it had too much momentum that kept it going to the third hop! 1:30: One of the adults escorted a sub-adult eagle out of their territory without incident. We packed up OW. A great day for activity at the nest, not so much for visitors. 4 adults and a fifth walk by. The Heat! 93 when we closed up shop and headed in. Reported to be 100 by 5 pm or so. It looks like chick #1 might be taking off from the nest this coming week? Or at least doing some major test runs? They are at 6 weeks , two days. Chicks leave the nest at 7-8 weeks. I hope somebody sees its first flight out. One last item, has anyone observed the adults or chicks facing east? Maybe Osprey Watch is at the time of day when they would be facing the sun, but Sue was thinking that when she has observed them later in the day they are still facing west? Maybe they like their privacy and they know we are nosy neighbors? What a thrill to have an opportunity to follow the progress of this osprey family! Remember Monday Meander, 6:30-8:00 pm at JBW with Steve. Hope to see many of you there. Happy birding all! Candace

Osprey Watch Saturday July 14 2018 Eliz & Deborah Calm, sunny 72 degrees with blue, cloudless sky, temperature rising continuously, until a warm 88 at 2 pm, but slight breeze in pm hours. We had 35 visitors total (including 20 visitors in the field trip group; 15 at the Pintail Shelter) About 60% of visitors to the Pintail Shelter were repeat visitors. Birds: Ospreys Crows - a murder Great Blue Heron Great Egret: Turkey Vulture Canada Geese Mallard Ducks Lazuli Bunting Deborah arrived at 10:10 am and Adult Female Osprey and all 3 chicks were all standing in nest. Chicks very vocal; at 10:20 pm Male Adult Osprey arrives from fishing, sits briefly on his favorite perching tree from SE., then delivers fish to nest to loud female and chicks. Adult Male then flew down to Pintail Pond and stood in the water. As I (Eliz) walked around the south end of Pintail Pond I could see and hear the female adult osprey and her 3 chicks standing in the nest; the adult male osprey was in a tree above me at one point, and alerted them (about me?) and they vocally responded. 10:30 am: A visitor with camera equipment was at the shelter when I arrived and he stayed for about an hour, enjoying the view, taking photos and shade from the unrelenting sun. It was his first time out at JBWP this season and we chatted about other sites he had been documenting. The crows provided a chorus of background chatter, that has become a constant behind the Pintail Shelter. 11 am: Deborah met field trip group at Kingfisher Marsh shelter and spent 30 minutes. Talking, showing photos and passing around egg and skill; group had spotting scope from Steve to view osprey nest. Translator was present to translate English into Spanish. 11:15 am: The adult female osprey was feeding a chick (did she keep some of the fish aside from previous feeding at 10:20 am? - no food was delivered by adult male osprey since then) 11:20 am: I had another group of visitors: 2 young adults and young female child who enjoyed the intimate view the spotting scope offered and talked about ospreys, including comparison of the nest building of osprey and robin (using robin nest in shelter), since most of the props were with Deborah. 11:30 am: All 3 chicks and adult female osprey; One of the chicks stretched out wings. A boy and 2 adults visited the shelter, and too enthralled with the close encounters with the chicks through the scope. A turkey vulture soared high for awhile. 11:35 am: An adult bald eagle appeared high to the west, causing the female adult osprey to perch on post above nest and vocalize. All 3 chicks were standing in the nest. The adult male osprey continued to attentively watch in that direction from a tree to the southeast, closer to Pintail Shelter than its favorite perch. The eagle never came close enough to view easily without binoculars, but stayed in that area for at least 15 minutes. 11:43 am: Lazuli bunting seen behind shelter 11:45 am: Single adult man (from Hillsboro) visited; he was very exhilarated with the view and shelter visit. He will be back soon, with his wife, if work schedule allows. He may be a potential future volunteer. 11:51 am: Turkey vulture seen high in sky in westerly direction 12:00 pm: Both adult ospreys vocialized. Male osprey flew to a tree, female osprey followed, then promptly returned. 12:15 pm: Visitors arrived (a young girl came with two adult males). At that time the interloper osprey approached from the southeast. 12:24 pm: Turkey vulture soared from southeast Adult female osprey & 2 chicks viewable in nest. 12:25 pm: Interloper arrives; Female adult osprey stays on post to guard Male returns and flies about with interloper who flies very close to nest several times. Interloper leaves & returns in 30 minutes 12:30 pm: All chicks visible standing in nest 2 adult older women visited, but were disinterested in the osprey family. After hearing from Deborah that there was a Lazuli Bunting seen nearby earlier, one of the women continuously played a recording of a Lazuli Bunting so that her friend could take a photograph; it continued for at least 20 minutes, although I finally and kindly but firmly told her that I would appreciate it if she would refrain from playing a recording of the bird song to attract a bird, that it was obviously agitated and was defending its territory from the intruder bird. It might be worthwhile to consider posting some kind of signage about doing that so that there’s another authority to point to, when attempting to get visitors to discontinue this disruptive behavior. I was asked twice by visitors whether Pintail Pond is stocked with fish. What is the answer to that question? 1 pm 3 adults visited us, having just moved from Salem to Hillsboro, were excited to continue to explore their new home and new osprey family to watch. They shared many of the local events they have visited and will definitely be repeat visitors. 1:13 pm: Only adult female osprey and 1 chick visible in nest. 1:25 pm: Adult female osprey and 2 chicks visible in nest. Male adult just left tree to south Turkey vulture flying overhead 1:30 pm: At end of our session, it had been a rather uneventful day, with only one feeding that occurred in a 3+ hour span.

Hello all! A glorious day out there at Pintail for Osprey Watch! A grand total of 25 enthusiastic guests, 13 of those were children. (yessss!!!) Paula did a stellar job of intercepting guests and directing them my way with a heads-up, and everyone got to witness and hear quite a show. A hot and humid day, only a slight occasional breeze. Geese, herons, egrets, a few killdeer and crows present foraging along Pintail. No eagles or hawks sighted. Observed behavior and activity much as expected at this stage: • Fairly constant vocalizations by the growing chicks, and communication between male and female: both begging and alert calls. Loud and awesome! • Female is regularly leaving the nest for longer periods of time, and has now officially joined the male by performing her own successful fishing trips though male still delivers the majority of meals (75% today) • All 3 chicks were observed self-feeding from cache in nest, though female continues to feed at times • Regular deliveries of very small (6 inches in length or so) fish; I witnessed at least 8 in total. On four of those occasions the timing was ideal and I was able to listen and spot, quickly directing guests back to the scope to observe the delivery and subsequent feeding. Suffice it to say everyone was thrilled! • Chick #3 is still noticeably smaller in size, and is often separate and assumes a submissive stance in the nest (low and back turned to others, etc.) But he/she is feeding and heck, still with us! • The male stays at the nest only long enough to deliver food, did not feed chicks. Post delivery he retreats to the sentinel ash for only a few minutes before departing the area • INTERLOPERS!!! Our new normal? On 2 occasions we actually had an Osprey *pair* arrive, cruise and survey the area in very close proximity to nest, in both tight and widening circles, both our male and female stepped up their vocalizing and followed/attempted to escort them out of the area. In area both times 3-5 minutes • The most striking activity I witnessed was when the interloping pair actually joined the male in his ash tree and all 3 perched together; our female left the nest and flushed out the pair. Came very close to direct contact between the 2 females! (As they were all perched, I was able to identify the pair as a male and a female Osprey.) • Also had sightings on 3 separate occasions of a single male Osprey performing the same surveying behavior, though no landing on the bar above the nest. • No 'helicoptering' at the nest quite yet or yoga stretches by the 3 chicks; though it is admittedly a bit early in the nestling schedule I was still hoping to see this... Always a thrill! The heat and lack of a breeze presumably didn't help there either. But, before we know it... One of the books I've provided "Inside an Osprey's Nest" continues to be particularly well-received out there, along with the books and other resources for children. *My Osprey Watch wagon has been replaced by one that Steve purchased for us, thank you! Overall, a very successful day out there, lots of fun getting the children engaged (sometimes a bit of a challenge - bring it!!!) and some great in depth questions for me and subsequent conversations. Though I was on my own out there I must say that things flowed quite well. Such a gift to be able to share those magnificent birds at such a magical sanctuary! Thank you to Steve and our entire team! Make it a great week everyone! Best, Sonia

volunteers- Dave Wesley Candace Hagen Heading out to OW there was a bit of breeze and some cloud cover, by the end of OW it was closing in on 75 degrees. 10:45-As we traveled to OW shelter, we could see one chick and the female. Once we were at the shelter and got the scopes set up, we could see the largest chick and the top of another head hunkered down in the nest. Dave noted that the eye of the largest chick is looking more yellow now. Suddenly, the female becomes very vocal and is spreading her wings over the chicks. We soon realize why. The osprey interloper is flying in from the southeast. It flew close to the nest, but did not stop and continued on towards the west. 10:50-female soared out from and then back to the nest. 11:05-male flies in with a fish drops it and is off again. The female jumps on the fish and for the first time all 3 chicks are visible and actively feeding. 11:15- female leaves the nest and is soaring first to north and then in large circle back to south. A few minutes later she heads off in the direction of the marsh with the duck blind. 11:23-female brings in a fish, two chicks are eating. 11:30-female leaves nest and is soaring up high 11:40-she heads towards the southeast over Waste Management area. Turkey vulture flying in from southwest. 11:55-male flies in from southeast, no food, flies by and to the sentinel tree. Dennis corrects me and advises it is the female. 12:05-female off sentinel tree and flies to northeast. Crows vocal in trees in northeast. 12:08-male back from the southwest,flies over nest, but doesn't stop, he has no food. A lot of vocalizing from the nest. 12:15-male flies off towards north/northwest. 12:20-female in with small amount of food. 12:25-female finished feeding chicks and eating herself. male in with a fish and lands on the nest. She proceeded to take the fish right out of the males talons. little to no protest from him and he leaves. 12:30-female feeding two chicks, the largest and possibly chick #2. one chick is on the southeast edge of nest with back to feeding. 12:40-smallest chick #3 moves over to the center of the nest where female and chick # 2 are still eating. it appears chick # 3 gets in on some of the feeding. 12:50-male comes in from southeast with a big fish, lands on the perch and then drops into nest with the fish. male immediately leaves for the sentinel tree. leaving female and chicks to the feast. 1:15- male leaves the sentinel tree. 1:20-male in with fish. dropped it into nest and flies off to sentinel tree. Shortly he is off again to the southwest. 1:25- last of our human visitors leave. 1:30- OW is wrapped up for the day. Great osprey action on the nest. A few times where the largest chick did some hopping and wing flapping. 6 feedings. Not sure how much the smallest chick managed to recover from leftovers or the attempts at getting in on feedings? It was a very light day for human visitors. Total of 7 adults and 3 children. we were figuring maybe people away for 4th of July weekend? Hopefully, Sonia on Sunday sees a bigger audience, people back from their holiday?! Thank-you Sonia for the use of your wagon. Makes getting out and back so much easier. Kids like your osprey books for the younger set. Birds today: • Osprey • Great Egret • Great Blue Heron • American Crow • Canada Geese(26) and 1 gosling • Killdeer, 2 young • Turkey Vulture • Ducks (sp)

July 1, 2018 – Wolfie and Sonia. Candace’s “play by play” report from Saturday’s OW is a hard act to follow, but I will do my best to share with everybody what Sonia and I observed. We had a total of 39 adults and 8 kids stopping at the shelter, asking questions, looking through the scopes and enjoying our osprey family. Weather was pleasant, mostly sunny with a slight refreshing breeze, although it warmed up after noon. We were happy to see all three chicks as we walked around Pintail Pond to the shelter. We sat up the station and two scopes and soon had our first visitors. Not much activity on the nest other than the chicks and the female “encouraging” the male to deliver food. This morning he did his job and by noon we had observed 4 fish deliveries. One Osprey interloper showed up and circled the nest. The male made a more or less “courtesy” call and left his perching tree in the west of the nest for a “this is my area” flight” without aggression towards the interloper. It got the message and just flew off, no drama. Only 30 minutes after delivery #4 at noon the male brought another fish and we were able to observe that the female fed chick #1 and #2, same reference as Candace used, with #1 being the biggest and three “the little one”. The male took care of #3 and we saw it actually being fed. Similar situation when another fish was delivered, not long after delivery #5. Still, chick #1 is noticeably bigger and looked beautiful, almost “ready to go” and was exercising its wings a bit, whereas the siblings are smaller, but all three seemed moving around in the nest, with #3 looking for shade next to the female. it looked like they all got to eat during the deliveries which happened in shorter succession. After six total deliveries while we were on duty the male took a break and disappeared from our views around 12:45. Just as we were packing up around 1:30 the female left the nest and flew NE leaving the chicks without any supervision. We still hadn’t seen the male and the female returned after about five minutes, no food though. It looks like during the morning the male delivered adequate food. We read that three chicks require about six pounds of fish total per day. Not knowing the size and weight of the deliveries we could not estimate if the “delivery man” was on target to meet the daily goal. Hopefully the “trend” we observed continues and the adults will be able to provide sufficient food for all three chicks. Sonia and I share Candace’s observation that the view of the nest is better from the west with no trees in the background. Not sure what the alternative is, Kingfisher Marsh shelter? Other birds observed: Great Blue Heron Great Egret Yellowleg, not sure which one, according to the Sibley range map neither one should be here in summer, Hhhm? Swainson’s Thrush [heard] Killdeer Black-headed Grosbeak [heard] Belted Kingfisher (2) Canada Geese Spotted Sandpiper Crow Common Yellowthroat [heard] Anna’s Hummingbird Song Sparrow [heard] Another successful OW day/weekend, looks like the word has gotten out and visitors are interested in seeing and learning about our osprey family.

June 30, 2018 Volunteer- Candace Hagen. As reference- Chick #1, the largest, most aggressive Chick #2, the next largest. less aggressive, ready in line after #1 gets his food. Chick #3, the smallest, not assertive, stands off to side during most feedings. 10:40- Today started out overcast and 60. No breeze. Female on the nest with 2 chicks visible. Female vocalizing as people trundled by on trail to south of nest. She settled down and was alert on the nest. Checking out the surroundings. 11:20-Male appeared from the s.w. and dropped a fish in the nest. The female south side of nest started shredding and turning her head to the side where chick #1 was ready with open mouth. Chick #1 received about 3:1 of the food compared to chick #2. Chick #3 sat on the north side of the nest with its back to the feeding in progress. #3 received no food. The adult male had dropped the fish and flew to the sentinel tree in the s.w. Two crows previously in the tree, vocalized, were joined by another crow and the three flew at the osprey a couple of times. Shortly, the crows retreated, not having dislodged the osprey from the tree. They moved to the shrubbery along the trail to the south of the pond. 11:45- Chick #1 stops feeding and moves to the east edge of the nest. #2 then starts getting the feeding. Chick #3 still on the north edge of the nest turned to face the female and chick #2 with what looked like interest in the feeding. After 5 minutes, #1 is back in front of female and taking any food she is giving up. The rest, the adult female is taking for herself. #2 is in the center of the nest, not eating. #3 not eating, sitting on the north edge of the nest with its back to the feeding. It has its neck outstretched and peering over the edge of the nest toward movement of geese in the pond. #3 has had no food since our watch started over an hour ago. Adult male on the sentinel tree, facing pond with light vocalizing. A scout troop numbering 10 + 7 adults has appeared on the west side of the pond headed to OW. Great egret in the water in front of southern-most man-made log structure,not bothered by the osprey as in the past. 11:55- Chick #1 still eating with the adult female, #2 in the center of the nest not eating, #3 has its back to the two siblings and the female. Occasionally, #3 casts furtive glances over his shoulder at the group, but turns back facing away from them. Scout troop # 866 were very curious about the nest, they all lined up behind the scope and listened to instructions regarding hands and how to view through the scope. They all lined up about 3 times each, explaining what they were seeing as they looked through the scope. Fun group and a pleasure to work with. I may be poor judge of age, but they appeared to be between 8-10 years old? They stayed about 20 minutes and then needed to head out. One of the troop leaders was going to show them the poison hemlock and discuss its fine properties on the way back. 12:00- Male osprey flew off to the southwest. 12:15- After 55 minutes of feeding on the first offering, 2 chicks are done eating. They settle to the bottom of the nest out of sight. Chick #3 still in the same place north side of nest with back to the others. 12:20- Killdeer vocalizing along the west side of pond. Egret at the north end of pond. 12:30-12:40- More human visitors came and went. 12:45- Egret and GBH have moved to the south end of pond in front of southern-most log. Male osprey not around to be perturbed. Crows, possibly a dozen,vocalizing loudly in trees behind the shelter. Morning started off so quiet with the crows with only two in sight. Their numbers steadily increasing and then about a dozen spending time down on the mud flats foraging. Female osprey leaves the nest, soaring first to the north and then circles round to the south in a large circle. She then soars higher directly over nest. Then she flies to the south behind the sentinel tree and over the trees. She leaves our sight, chicks unattended. 12:55- Female returns with small amount of food, not discernible as to what it was. Within next 5 minutes she leaves the nest again and heads to east towards the heronry. Soaring higher and higher, as though she is scoping out the fields or taking a sweeping view for predators? Disappears from view. 1:10- Chicks #1 and #2 are up and alert in the nest. #3 not in view. 1:15- Male osprey lands on the perch with whole fish in his talons. He is looking all around. He drops into the north side of the nest with the fish, appears to drop it and then looks all around. 1:20-All three chicks are up, alert and vocalizing in front of him. He makes no attempt at ripping the fish for anyone. #1 chick moves to the south side of the nest, faces the male and siblings. Adult male leaves the nest for a quick soar overhead. 1:28-Male returns to the nest, begins to rip the fish. Chick #1 is laying down on the berm on the south side of the nest. 1:35- Female returns without food and soars directly into the nest right at the feet of the male, north side of nest. Male takes the cue and leaves the area to the s.w. Female is ripping the fish for herself. 1:45- Bald eagle soaring high in the n.e. One chick, balancing on the north of nest, looking around. Starling on perch not even noticed. Female on the nest looking around. 2:05- Female and one chick up and alert. 2:30- Male flies in with food and immediately leaves. I miss the direction he went. Possibly around this time #3 chick may have gotten some food from the female? Not observed. A red-tail hawk is seen soaring overhead. Then another bird is seen higher above the nest soaring, not computing what this species is. 2:35- Suddenly the male is back from the sw, and headed after two birds. At first, it seemed like he was chasing after two hawks, but as they flew closer and out of the bright sun it became apparent that the red-tail had its talons extended full length as it flew after the 2nd bird which was a sub-adult eagle, and the osprey was going after both of them. The hawk, with its talons extended continued after the eagle for several minutes. Osprey right with them. The eagle was banished and the hawk disappeared. Deborah was there to see it, also Bill and Millie from lwtb's! A young mom, with her two little boys, was there to witness it. The boys were too young to appreciate what was going on above their heads, but mom was thrilled! 2:45- called in to HQ and advised OW would be heading in. It was a great day out there. Warmed up to about 75. Glad we have the shelter! We had 19 adults and 14 children, for a total of 33 visitors. It has been mentioned several times by visitors that the view is better from the west side of the pond. There is not foliage behind the nest from some view point on that side. Chicks are better seen outlined against the sky? Birds out and about today, that were observed or heard between the high points of osprey activity: • Osprey • Great Egret • Great Blue Heron • Canada Geese, 1 gosling • Ducks(sp), 1 duckling • Tree Swallows • Killdeer • American Crow • Bald Eagle • Black-headed Grosbeak (heard) • Woodpecker (sp) (heard) • European Starling • Red-tailed Hawk • Sub-adult Eagle • Song Sparrow

Osprey Watch 2018 @ Jackson Bottom Wetlands Preserve - Sunday, 17.June.2018 Volunteers: Eliz Linser & Candace Hagen I arrived just before 10 am at JBWP parking lot when Candace joined me; the parking lot already had a dozen cars parked. We packed up our gear, including both spotting scopes and lots of supporting tabling props since Sonia was so kind to loan us her wagon for the Osprey Watch 2018 season. (Thank you, Sonia!) It was already a hot, dry day - the temperature increasing steadily throughout the day into the low 80’s. Indeed, there was rarely a cloud in the sky, but a slight breeze was comfortable for the humans and provided extra lift for the birds to soar. The morning walk was punctuated by songbirds announcing their territories - black headed grosbeak, ever present robin and song sparrow. As we rounded the Pintail Pond, we could see the female osprey on the nest and hear the young chicks crying for food. When we arrived at the Pintail Pond shelter (10:30 am), there was a friendly group of 3 - older father and his 2 adult children; one was photographing the osprey family on the nest. The male osprey had just returned to the nest with a small rodent, possibly a vole, and a fish. He continued to leave the nest to hunt, returning with fish for the remainder of my stay. The first hour there, he left on 3 occasions, returning with fish each time. It appeared that the male ate the fish heads, leaving the remainder for the family. At times the male sat atop the nest pole, other times he joined the family. The third chick, that seems possibly the last egg, is not as robust and aggressive as its 2 siblings. The female osprey feeds it if it is there with gape ready, but other times it sits with the male, who does not feed it. Being Father’s Day, families with young children continuously made the trek around Pintail Pond to visit our site. At times it became a little challenging, as the little ones instinctively would grab hold of the scope, requiring constant adjustments. I found if they could climb upon the stool, put their hands behind their backs, then take one hand out to cover an eye, ask their adult to help stabilize their child (more comfortable for young one than stranger, and more appropriate), it worked best. The first family had 4 young boys who were delightful and well equipped with their own backpacks and camelbacks, very interested in all of the photographs, picture books and osprey egg and skull, even the stuffed fish. All visitors - children, parents, grandparents, single hikers, were interested in the wondrous sight of the osprey family and 3 chicks sharing a meal or staying out of the intense sunlight by taking cover under their parent’s wings. Most of our visitors (68 total, roughly half were children) were from the area, and as far away as Newberg (that particular mother was a teacher and visited JBWP in 1990s before the many changes that occurred, and was sharing the differences). About 25% were visiting JBWP for the first time. Everyone had a lot of genuine interest and asked a fair amount of questions about the ospreys and some about other residents. At one point, the interloper Osprey which visited the previous day(s) made a brief visit, but did not stop at the nest site. A mature bald eagle could been seen from a distance, high in the sky, riding the steady air flow. A turkey vulture flew closer to the nest. A pair of great white egrets strolled through the pond and a great blue heron, killdeers and sandpipers hung close to the water’s edge. Candace left a little earlier than myself; I was at the shelter until 1:50 pm, as I continuously had more visitors interested in the scope. I waited until I didn’t see others. I was so hungry for seafood after watching the ospreys dine on fish all day!

Osprey Watch Report by Sonia Redmond: The male Osprey was absent for much of our visit, though he did finally arrive around 1:30 with a fish delivery which was greedily accepted, and he returned no more than 10 minutes later with a second course. Will share here key observations that are really sticking with me thus far this season: • The crows! Ever present, either cruising down along Pintail or perched to the south, frequent fly-bys and encounters in very close proximity to the Osprey nest • The male Osprey *most often* seems to depart to and returns from the southwest, though he has been seen returning with fish from the north • Both the male and female Osprey continue to repeatedly "dive bomb" egrets in Pintail at the base of the nest pole. Today we then witnessed an egret fly by the nest slowly at nest level, and actually turned a semicircle. (Candace and I were surprised and then laughing, and chose to interpret that as some kind of return communicative display of disgust/displeasure. "Make my day," etc...) Our photographer visitor managed to capture a shot of it; he returned to share it with us. He was quite thrilled. So great! • The female Osprey continues to gather nest material, even briefly leaving the nest when the male is not in the immediate area to gather material and quickly return to the nest with it. • The female is particularly vocal (and therefore helpful to us) this season; her begging and alert calls always seem to direct or signal activity thus far • This is the first week this season that I have *not* witnessed a direct confrontation (actual aggressive interaction/attacks) between the osprey and eagles: usually immature eagles promptly confronted and escorted out of the area by the male osprey, though the female left the nest once for this purpose when the male was absent. • ***INTERLOPER! For the 2nd day in a row, a 3rd osprey, a sleek male, approached the nest from the south, circled repeatedly as the pair both guarded the nest AND ACTUALLY LANDED on the triangular shepherd's hook directly above the family of 5 in the nest. !!!!! Of course plenty of vocalizing all around, and eventually our male rose up out of the nest and flushed him out. However, he returned to the area briefly to slowly circle yet again for more of our visitors to see. Absolutely mind-blowing to witness this 2 days in a row for me! From my own research, this could be explained a number of ways, but obviously just can't be interpreted with certainty. But fascinating!

Hillsboro Parks & Recreation Commissioners visit the nest and see two chicks plus adult on the nest.

06/09/2018 by Jackson
Sue Nuthmann reports seeing a picture on a photographers long-lens camera showing 3 chicks in the nest.

06/05/2018 by Jackson
Steve Engel observed two chicks in the nest with both adults present, one of them actively feeding the chicks.

06/01/2018 by Jackson
Sonia Redmond observed apparent feeding behavior as well as incubation behavior. The next day Laura Trunk reported movement seen inside the nest.

05/23/2018 by Jackson
Alison Perkins observed behavior suggesting there was more than just eggs beneath the adult on the nest - the adult standing and spending minutes with head lowered focused on something between its legs. However, incubation behavior predominated for the next week.

We had an Open House today and Sonia Redmond and Wolfgang Dempke ran the first Osprey Watch of the season: We witnessed several fish deliveries (one was actually refused!) and some shift changes; at one point the female had lunch delivered, and took off to a nearby ash tree to dine. She then spent about 80 minutes perched, preening and posing, and at one point descended into Pintail at the base of the pole to bathe. That was a first for both Wolfie and I to witness, and oh my, she put on a show for us! She splished and splashed most enthusiastically (I am not interpreting here, it was obvious ) for several minutes before returning to her perch for more preening. Wolfie and I were delighted, and couldn't help but chuckle as we watched her. Both the male and female were fairly vocal, and at one point the female alerted to a turkey vulture that came by too low and slow for her comfort. Overall, just happy to see that there was regular activity and sightings to share with our guests, particularly since the incubation period can be fairly quiet. We of course did our best to encourage all of our visitors to return in June and July for some more epic Osprey watching.

The female was first seen on 3/30 late in the afternoon. The male put on quite a show when she arrived. They were observed copulating that same day. Both birds brought sticks to the nest over the next weeks. Sightings of other osprey checking out the pair were not uncommon. Bald eagle activity in the area as well. The pair defending well against all comers so far.

03/27/2018 by Jackson
We all waited with bated breath for the osprey to return and find the new nest pole, platform and perch, now located within Pintail Pond instead of on the edge, and with no existing nest to repair, just one to be built from ground up! The male arrived 3/27, almost a week later than last year, and began gathering sticks right away.

2017 is the 5th year this nest site has been occupied. The nest pole was erected in fall of 2012 and the first pair nested in spring 2013. They fledged one chick in 2013; failed in 2014, 2 chicks fledged in 2015 and 2016. The 2017 season is off to a good start. There have been more visits than usual by other osprey, one and two at a time, throughout April and May. The local pair seems to be weathering it all just fine so far. Up to 9 bald eagles can be in the area at one time as well.

Around 4:30 I went to put up trail closure signs around the nest. No birds were seen until I put up the final sign, then I heard calling and looked back at the nest - there was a bird on it. Had it been there the whole time or did it fly in unobserved? As it called the male dove out of the sky with a large fish and landed in the nest. The female took the fish and flew to a perch just south of the nest. The male perched on the cross bar for a few minutes then flew to the female and they copulated.

On 3/13/15 the first osprey of the year was seen over Jackson Bottom wetlands but it was not associating with the nest platform. On 3/24 one bird was observed perched near the nest platform and returning to its perch after short flights over pintail pond during which it vocalized and dropped its legs vertically. On 3/28/15 Marlowe Kissinger photographed the first instance of a pair perched on the nest. Territorial flight was observed 3/28 - 29 - 30. There are up to 5 bald eagles at a time in the air space over the wetlands this past week and an adult pair is nesting about 1 mile north of the osprey nest. One of those adult eagles (?) frequently perches in a doug fir about 1/2 mile sw of the osprey nest.

Nest pole installed 2012 (date?). Occupied 2013 and fledged 1 chick. Dates for 2014 nest activity come from eBird reports chiefly by Joe Blowers and Char Corkran and from personal conversation with Rick Balazs. July 11 nest failure date represents end of several days of no adult activity at nest after a period of incubation. It is unknown if eggs hatched or not. During incubation there were observations of 1 and 2 OTHER osprey in the airspace near the nest.
