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.
Saw 1 bird in the pine tree and 1 bird in nest! I think it's the adult male and the chick. When 10 minutes was almost up, the bird in the nest (chick?), started chirping loudly and flew out of nest to perch near his Dad in the pine tree, still chirping loudly. Soon Dad joined in!
There were at least 2 other ospreys actively fishing over Broad Cove so they might have been warning them to stay clear.
Clearly saw 2 birds perched in nearby pine tree. One started chirping and flew into the nest to meet a bird flying in with a fish. After leaving the fish, he flew into the pine tree to join the other bird. I think it was the chick that flew into the nest. It appears that all 3 birds are still here.
7/22/23 - 2 adults in nest when I arrived. One flew out and over the cove then returned to a nearby tree. When I looked more closely at the tree, I'm pretty sure I saw a chick sitting in it. When the adult flew out the chick stayed put. I'm considering date of fledging to be 7/22.
4/2/23 - observed pair on the nest for the first time! Male (Keckie) flew down to beach and came back with a stick. Then he flew out over the cove and away.
4/4/23 - both birds on nest. Keckie flew off and circled over the cove for awhile, chased an interloper away. Nippie flew off the nest and perched in nearby tree.
Observed female in incubating posture! Meanwhile, Keckie, the male was busy trying to keep 5 other chirping, fishing ospreys away from their nest. He alternately chased them and ignored them, and eventually he brought a fish into the nest, deposited it and left. I watched all 6 birds fly around for at least 10 minutes.
2 birds in nest (chicks?). 1 flew into the top of nearby pine tree the other flew down, caught a fish & brought it into nest. When 2 interloping ospreys flew by, one of my adult pair flew up from behind the nest to chase them away. While this was going on, the chick in nest w/fish, flew into the pine tree with the fish to share it with the other chick! The adult flew back to nest to find it empty!
Forgot to say that I also saw a wing of one of the chicks come up. There was no adult in the next for awhile. She left to chase away a couple of interlopers who were chirping and circling over the cove. I hope Keckie is okay. He's usually the one who chases away the threats. Haven't seen 2 adults for awhile.
We have a hatch! Nippie was on the nest but not in the incubating position. Keckie was in the large pine where he sits as chicks start hatching. He flew out over the water but them perched back in the tree w/o bringing breakfast.
I saw a bird for the first time this year on the nest on 3/30/31. While he was sitting there, another osprey flew nearby carrying a fish but he flew off in a different direction so obviously not the mate. I think the bird in the nest is the male, Kecki. Welcome back!!!
My son visited the nest daily while I was away from 9/5 until 9/9. He didn't see Chirpy at all. Today I floated in my kayak under the nest. On my way over I saw 2 ospreys fishing over the cove. As I was about to leave the nest, an osprey flew towards me and towards Chirpie's nest with a fish, then veered off into the trees near the nest to eat the fish. No way of knowing if this was Chirpie or not. As I was pulling my kayak up onto the beach, 2 ospreys were fishing over the cove.
Floating in kayak under nest. There was an osprey perched on a pole in the water with a fish. When he saw me over by the nest he flew off with the fish, chirping, and went behind the trees near the nest. He didn't come back into nest. There was also an osprey perched in a small tree in the bog near the nest.
Today my chick was very entertaining. When I started watching, he was fishing over the cove. He dove unsuccessfully a couple of times, then flew up into a tree and perched there for awhile, chirping now and then. Then he flew down, fished again, came up with nothing, then landed on a sandy spot, in water up to his breast, and sat there for at least 5 minutes splashing around, giving himself a bath. He finally flew up into the nest, chirped a bit, then flew away. It's the most active he's been while I've been observing him, except for when he's been chasing interlopers away.
I kayaked over the the nest. It was empty but when 2 ospreys flew over the cove, crazy loud chirping came from the trees near the nest, probably my chick. As the 2 birds continued to circle over the cove and fly close to the nest, my chick eventually flew out of the trees and chased them away. He was chirping the whole time!
The adult ospreys might have already migrated but they taught their chick well. He was a late flyer but today I saw him defending his nest from what I think was another chick. He was perched in a nearby tree when another young bird flew by. He flew after him, swooping and diving at the other bird and chased him out of the area. Then he came back to the nest. The persistent interloper returned and started swooping down on him in the nest. The chick chirped threateningly, staying in the nest, and eventually the other bird flew away. He's definitely scrappy!
Observed nest from my kayak. One bird in nest (chick?) that chirped when I beached my kayak nearby to remove spiders from boat. Just as I was paddling away he started chirping loudly and another bird flew into nest.
Today is day 59 for a chick that hatched on or around 6/3 to fledge. The chick was alone in nest, then Nippie flew in. They were chirping but I couldn't see anything nearby that they were chirping at. The chick should be fledging soon. He was stretching his wings today! Good sign!
Observed nest from my kayak. Nippie and the chick were in the nest. They chirped half heartedly at me when I pulled up but as I floated around, they started agitated chirping when an osprey interloper flew by. He circled the nest a couple of times then perched in a nearby tree. Keckie didn't come out to defend the nest so he must have been off fishing. Eventually, the interloper flew off.
Nippie and the chick in nest. I don't think the chick has fledged yet and I'm starting to wonder if Nippie flies! Seems like whenever I watch the nest they are just sitting there together and Keckie is flying in and out. Today, he flew in with a fish and the chick chirped excitedly.
I watched the nest from my kayak. Nippie and the chick were in the nest and when they started chirping at me, Keckie flew out of a nearby tree and into the nest. He stayed there til I started to paddle away, then he flew off. It was great to see all 3 in the nest!
The bush/weed that had been growing in the nest was completely gone! I had a clear view of Nippie and the chick. Keckie flew out of the trees, chirping at an interloper. He flew off after chasing it away.
3 birds in nest. Keckie left the nest to fish. He caught one, just by barely dipping below the surface.He was adjusting it in his talons and heading towards the nest, when another bird flew down and also caught a fish. Keckie switched directions and took the time to chirp at and chase away the interloper, before flying back to the nest. I guess he was hungry because he did NOT go to the nest and share the fish. He disappeared into a tree behind the nest to eat it himself (?) Nippie was quiet so maybe he had already fed his family. The chick looked small.
Hung out in my kayak near the nest for 10 minutes and definitely saw the chick. When i arrived at the nest, both adults were in the nest with the chick, but Keckie flew out and down into the trees near the nest. Nippie remained in the nest with the chick. There appears to be only and I don't think it has fledged yet. Definitely smaller than the stone bridge chicks.
Nippie on nest. I'm pretty sure I could see the chick also. An interloper flew near the nest and Keckie flew out of the trees to chase it away while Nippie chirped. Keckie flew away after the interloper.
As I approached in my kayak I could see 2 birds in nest - looked like an adult and a chick. The adult was chirping loudly at an interloping osprey flying by the nest. She stopped chirping at him as he flew away, then proceeded to chirp at me until I paddled away to satisfy her.
I saw a chick for the first time today! One bird flew away from the nest just as I was arriving, leaving one adult in the nest. As I watched, I could tell she was feeding a chick and it was visible. Only one so far.
One bird in nest. Another bird flew in with a fish. They were both perched on the edge of the nest but still no sign of chicks. The huge weed that I was worried about seems to be dying (turning brown).
One bird sitting on edge of nest, chirping at another bird circling overhead. Eventually she left the nest to drive off the interloper who flew farther out over the cove but didn't leave until the crows chased it away. She came back to the nest.
one bird in nest, not in incubating position. It appears hatching has started! There is a huge weed on the right side of the nest that keeps getting bigger. I'm afraid it's going to push the birds out of the nest. 6/3/2020
One bird in nest. I wasn't sure if she was in the incubating posture or not. Chicks are due to hatch this week or as early as this past weekend. I'm watching closely. Their nest gets deeper every year so it's hard to tell.
Nippie incubating. She flew off nest, chirping at a person who was picking up trash under the nest. She eventually flew back, settling on eggs. Meanwhile, Keckie was flying over the cove fishing. When he was unsuccessful, he flew away.
4/15 - One bird in nest. When it flew out over cove it was immediately harassed by a crow. The osprey chased the crow, and this went back & forth, until the other osprey showed up. One went back to the nest, the other continued the crow drama then perched in a nearby tree after the crow flew away. No eggs yet.
I've been observing this nest for 12 years so I named the birds. Niippie (F) and Keckie (M), is how I'll refer to them from now on. Nippie in nest, chirping nervously at anything that flew by, sea gull, crow...finally Keckie flew into nest, "empty-taloned". Nippie chirped excitedly to see him, and continued to chirp until he flew off again. Probably to find dinner! No eggs yet.
today I saw both birds for the first time. I felt like a voyeur because I saw osprey sex twice while I was watching the nest. The male flew down and brought up some nesting material. 2 other ospreys flew by and I noticed the pair didn't seem bothered by these birds like they are when they have the chicks in the nest.
