platform built on top of dead, topped-off tree in property owner's front yard
this nest was unoccupied last season. today, while checking on another nest, i saw an osprey bringing nesting material to the nest. i can see another of my nests from this same spot.
What to look for
Look for 2 adults on the nest. The adult pair will show pair bonding behaviors such as vocalizations, aerial sky dances, and the male feeding the female fish. You may see the pair copulating, which typically begins 14 days before laying eggs.
Females will lay 1 - 4 eggs at a rate of one egg every 1 - 2 days. After laying, incubation starts. Look for adults taking turns sitting low in the nest incubating eggs. The incubation period can last 35 - 43 days.
Chicks hatch ~39 days after incubation begins. Look for adults bringing food to the nest and making "head bows" into the center. Chicks typically can't be seen until they are 2 - 3 weeks old, so feeding behavior is the only way to know chicks are there.
Around 4 weeks after hatching, look for the heads of chicks to show over the rim of the nest, particularly when adults bring food to the nest. Other times they lie flat and are harder to see. Count the number of chicks in the nest before they learn to fly
Chicks begin flying around 7 - 8 weeks old, and are still fed by the adults. Count the number of chicks who have successfully fledged the nest and are observed flying.
Chick Last Observed
4 - 10 weeks after fledging, chicks begin leaving the nest area to migrate south, once they have learned to fly and feed themselves. Record the date that the last chick left the nest.
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.
i'm baffled by this nest. mom laying down in nest, almost looks like she's still incubating, which would not be a good sign for a successful season. will probably talk to paulette/mark next round if i don't see something different
not sure what's going on here. i might have been mistaken about incubation starting 5/6. today, no one was home when i arrived, then mom flew in and began fussing in the nest bowl. never did see her lay back down.
finally met the property owners, paulette and mark welch. they advised me that the male arrived on 4/9, and the female arrived a couple days later - so way earlier than i had observed! female spending a lot of time in nest today, it might be getting close to egg laying time for this pair...
2 bobbleheads! one chick totally dominating the other, lots of beak bonking, mom standing in nest, chick is food begging, hope dad arrives with a big one soon!!! i'm estimating first hatch was within a day or so of 6/21 observations...
mom laying in nest, appears to be sitting higher, but no confirmation of chicks yet. located male osprey in tree by river a few yards away, fresh fish in his talons. no food calling from mom, dad taking his time eating, must not be the first fish of the day the way they are both behaving. i think we either have a chick or will in the next 24-48 hours, stay tuned...
dad incubating when i arrived, mom flew in a few moments later and took over. dad flew off, a minute later here comes that male osprey w/fish that was flying around the oldenberg and riverbank nests about 10 minutes ago! this nest is right across the channel from those two nests. i'm guessing this is an unattached male looking for a mate!
oh, boy, another mystery nest (along with gho nest). both standing in nest when i arrived, appeared female was finishing a fish. all of a sudden, the male got into the nest bowl and did that shimmy action that means he's either making a deep nest cup or trying to get rid of someone else's eggs. female remained standing on side of nest, no squawking. male left nest and came right back in for a copulation date. this male has speckles sprinkled on his breast. afterwards, male left nest and female got into nest bowl and started moving big bunches of nesting material around herself. this nest was one of the two nests dealing with a lot of chaos the past couple weeks; i'm wondering if maybe this male ended up being the winner? anyway, this is one of 3 nests still without confirmation of eggs. i checked last year's data, and they started late then, too (5/15), so maybe everything is going according to plan and i just don't know it...
geez, just when i'm about to give up on seeing chicks here this year, i arrive to see 3 ospreys chasing each other right above this nest. i was curious why at least one of them wasn't in the nest protecting it, then the mystery deepened when a 4th osprey joined the brouhaha. at least 2 of the first 3 were males, from what i could tell, but i have no idea about the 4th osprey. i have to believe they were squabbling over who gets the nest, will go back out tomorrow
good lord, chick is back in the nest (pics posted). guess that answers the question of whose dad was seen fishing yesterday! i'm a bit concerned for her at this point, as there are no other ospreys around that i can see.
empty nest. located one of the dads fishing from his favorite perch over the river; never have figured out if he belongs with this nest or the 'across oldenburg' nest, since they are within spitting distance of each other. in any event, no chick today, only one, lone male adult.
2 female chicks in nest, one eating a fish, the other complaining. a few minutes later, here comes dad with a quick food drop, and the other chick got that one, so i left the two of them happily mantling their lunch.
arrived at same time dad did w/breakfast. mom fed 2 chicks a few bites, then they appeared disinterested. never saw a 3rd chick? terrible wind storm thursday night, but this nest is in someone's front yard, they would have noticed if a chick was blown out, right? they were all fine and healthy a week ago...
omg, there are 3 chicks in this nest! unlike steel bridge, they all appear to be the same size and thriving. 2 chicks getting fed with 1 not paying attention, either because he's the alpha chick already full or the 3rd chick waiting his turn. i sorely wish my steel bridge runt looked as good...
i estimated the hatch date based on the size of the chick in the nest today - mom was eating most of the fish, with very tiny bites being fed to a little one/s deep in the nest bowl. only one tip-top of head appeared briefly.
it's not a dream - there is a female incubating in this nest! the nest itself could use a lot more sticks; here's hoping the male is out working to make that happen! wish i knew if this was the dockstader island pair that got displaced about a mile up the road....i hope so!
one lone osprey on nest. as i was leaving, another osprey flew in with a fish! just as i was beginning to think we had a pair here, the fish-carrying bird, which appeared to be another male, took the fish across the street and proceeded to eat it, all the while the osprey in the nest kept its back to the other osprey and never said a word. so now i'm wondering if bird w/fish wasn't just taunting the bird in/nest? it's a bit too late to start making babies, so i continue to think this lone male is out of luck this year... :*(
