3 big birds on the nest with one flying onto the tall T perch tells me at least one is flying

06/26/2020 by baygirl
possibly 2 chicks vis today

06/10/2020 by baygirl
chick feeding but unable to count heads at this time, loose pair remains on the duckblind no evidence of nesting there. they could be a problem for fledglings from this nest

05/12/2020 by baygirl
i believe the duck blind that is close to this nest platform now has a new pair on it. i hope this does not cause this pairs nesting to fail.

04/23/2020 by baygirl
i witnessed an incredible eagle osprey battle today with the male and female from this nest attempting to thwart the air attack of an immature bald eagle who wanted the males fish. the female was off her eggs for the battle as was the female at nearby 85 Quillens nest. The eagle locked onto the male osprey who then dropped the fish and flew back to his fave perch. the other osprey escorted eagle out of their airspace. I will check back on the male tmr because in my mind he is an amazing foster dad and hope he is oK!

04/20/2020 by baygirl
finally can actually confirm incubating behavior today, mate on sign post nearby

04/14/2020 by baygirl
female on nest this afternoon calling to male on sign post with fish

10/01/2019 by baygirl
adult male still at nest site area today when we placed a new platform on southern most island at Cliff's Isles.

09/30/2019 by baygirl
passed by this nest site today as we are prepping another location for Cliff's Isles osprey platform #2, the adult male was once again on his favorite sign post. Looks like this season as in years past a few ospreys will once again remain into the first week or later of October!

09/28/2019 by baygirl
adult male with fish on his favorite sign post today as we passed by in boat.

09/22/2019 by baygirl
adult male flew in with good sized fish and landed on his fave guard perch to eat today. one of the few adult males still visible on the bay and creek

09/14/2019 by baygirl
one juv on nest 1 adult on pole

09/02/2019 by baygirl
2 juveniles on nest, one with fish, and one adult on near pole and one adult on duck blind with fish, nice to see both adults still at the nest site that had 4 fledglings

07/31/2019 by baygirl
all 4 in nest this morning with a few extras hanging nearby

07/26/2019 by baygirl
this nest often has 5 fledglings, the more the merrier here

06/27/2019 by baygirl
i passed by on 6-17 and saw 2 chicks, but 6- 22 was the first day I saw 3 growing chicks peering out over the nest and then under momma, in the shade, was a tiny runt, sigh, and again on 6-27 I saw all 4 chicks being fed by momma but this time, the runt appears to be catching up in size so fingers crossed this adult pair can fledge all 4. the irony is that this pair fostered a chick in 2018 from a fallen snag nest with 4 chicks, so now its their turn to care for 4 and from observing them care for the foster, i know the male is a fishing machine and they can, if they are undisturbed, able to feed all 4.

05/29/2019 by baygirl
female deep in nest, mate on pole, can not yet confirm hatchlings

05/26/2019 by baygirl
passed nest by boat, female was low in nest, could not confirm hatchlings, male on one of his fave sign posts

05/12/2019 by baygirl
one deep in nest, one on sign post with fish. heavy rain and wind for past 2 days

05/03/2019 by baygirl
one deep in nest today did not see second

04/13/2019 by baygirl
one on nest, one with fish on sign post

04/04/2019 by baygirl

one on nest perch today

09/20/2018 by baygirl
checked the area by boat today, no osprey on any of the perches or platforms into or in beach cove. what a season it was with this nest, and " foster" being the highlight. Godspeed Foster and Fledge.

09/16/2018 by baygirl
one osprey on the platform t perch today but could not see if it was an adult or juv

09/10/2018 by baygirl
"Foster" on corner board and adult male on platform perch today

09/07/2018 by baygirl
one juvenile on nest today but not close enough to id which it was, no adult seen. 9-3-18 both juveniles,Foster and the natal juvenile on the nest calling for the fish the adult female had on the far sign post. good to see her still at the nest this long with Foster! Doubtful I will see her again this season. time to migrate

08/18/2018 by baygirl
both juveniles on the nest today, one on the t perch and one corner board, one adult on pole but i was not able to ID which adult. glad to see Foster is doing well. yesterday she was on the sign post and the step sibling was laying deep in the nest. i would expect the other way around but it seems she is quite confident and takes many spins around the cove to try to fish, i hope to see her catch one soon! i believe the step sib is a male, very white chest and smaller than Foster. Foster has a medium necklace

08/17/2018 by baygirl
"Foster" fledged on 8-5-18. I decided to not add her to this nests count as I will report the new snag nest in Dagsboro where she was hatched in a nest of 4 chicks. Foster fell from the nest on 7-25-18. The property owners saw her get pushed out when a fledgling landed hard in the nest. I was called by Tristate Bird Rescue to retrieve the bird- if possible. I found the chick in the marsh, about 25 feet out from the dense phragmites that grows under the nest.She was almost full grown but she was a runt, emaciated and had not yet developed her chest muscles to fly so she could not be released back to the high snag nest. Her parents had not been caring for her very well and she needed a new start at life. After she was checked out at the bird center she was brought back to me to find a suitable foster nest and I chose this one because there was just one chick of similar age and I could easily approach the nest platform by boat. Unfortunately after the adults returned to the nest to find a new youngster, the adult female and new sibling began to bully the foster chick. In hindsight, since Foster was a runt, we now think it may have been better to place the chick in a nest with a slightly younger chick. It is rare to have to place an 8-9 week chick in a new nest. most fosters are much younger. I could write a book about the 8 days until she fledged but it was an incredible experience observing her behavior and that of the others in the nest. She was very submissive and after 4 days she was allowed to enter the center of the nest and to finally lay down. She was well fed from minute one though and the adult male never bullied her.I have continued to monitor her every single day and she is thriving. both adults remain at the nest and bring fish to both of the juveniles. "Finding Foster" was the best experience of this osprey nesting season!

07/28/2018 by baygirl
natal chick was flushed off nest today when I placed a foster chick rescued thru Tristate Bird rescue from a snag nest in Dagsboro. I am doing the foster project with the mentoring of USFW Poplar Island Team. the fledgling may have been flying a day or 2 before i flushed it. the foster is a runt but same age as fledgling. will document the fosters story here.if the foster fledges I will add her to this nests count.

07/24/2018 by baygirl
one on favorite sign post, one on platform t perch and chick self feeding in the nest today. should be flying soon

07/22/2018 by baygirl
one adult visible on the platform from a distance this evening, could not see a chick

07/16/2018 by baygirl
one growing chick on the nest corner with adult female shading from the corner board of platform and adult male on nearby duck blind

06/16/2018 by baygirl
female perched on nest rim with one chick visible

06/10/2018 by baygirl
one feeding with second adult on nest rim today around 2:30 pm

06/05/2018 by baygirl
chicks probably hatched within past few days but today i finally saw one adult on nest rim appeared to be feeding and one on fave sign post eating fish. white debris still in nest

06/03/2018 by baygirl
still have not confirmed feeding behavior due to bad weather and distance from land but i can see the female deep in the nest and the male perched on his fave pole, will try to confirm chicks this coming week

05/19/2018 by baygirl
I check this nest platform often, and tho its from a distance I can always see one deep in the nest and usually the second on the nearby pole eating a fish as I saw today.

04/25/2018 by baygirl
4-23-18 was first day I could confirm one deep in the nest showing incubating behavior with second spending time on the favored sign pole.

04/16/2018 by baygirl
one picking around in the nest with the other on the sign pole eating a fish.

04/11/2018 by baygirl
Female fussing in the nest and another osprey on the new duckblind nearby. I sure hope that is the mate and he is not interested in nesting on the duckblind!

04/07/2018 by baygirl
female has been busy at the nest with the male often eating a fish on the nearby sign post. incubation should be very soon....

04/02/2018 by baygirl
I have been seeing both on the nest or most often the male on his favorite sign post and the female on the nest. today just one was fixing the nest but as last year the nest seems sparse.

03/25/2018 by baygirl
Today around 5 pm I finally saw both adults at the nest area. It appeared the female was in the nest and the male was eating a fish on his favorite near by sign pole.

03/24/2018 by baygirl
1 osprey on the platform eating a fish yesterday and today.

09/26/2017 by baygirl
9-23-17 one adult male on pole used by the adults from this nest site

09/21/2017 by baygirl
update today - no osprey at nest site but one adult on a pole at other end of the island.

09/21/2017 by baygirl
end of season: last adult female seen 9-06-17, last adult male seen on sign post 9-17-17. one juvenile may still be lingering. will update if I see it again.

07/30/2017 by baygirl
I pulled the boat in view of this island nest and watched as one chick was helicoptering like a ping pong ball across the nest. Mom and sibling ducked out of the way and then suddenly the chick took off and made 2 passes around the nest, sort of swaying in the heavy wind and then it made a beeline for the nest and grabbed the high platform T-perch in a clumsy landing but a successful landing nonetheless. There is a funny sound osprey make when they are learning to fly from the is unmistakable and very gleeful. My heart feels the same way when I watch them!

07/29/2017 by baygirl
2 large chicks on the nest due to fledge...

06/22/2017 by baygirl
I saw chick feeding behavior on June 10 but surely hatchling (s) arrived before then. On June 18 I saw one chick getting fed at the nest as I drove by in my boat.

06/08/2017 by baygirl
still have not confirmed hatchlings at this nest but one adult is always in the nest and one on the pole when I check on the birds. hope to spend enough time tmr to observe via boat until I get my confirmation!

05/25/2017 by baygirl
hard to get a good view of this pair today but one osprey deep in the nest and one on the pole. will take out boat tomorrow and will be much closer to see how they are doing with increasing boat traffic.

05/07/2017 by baygirl
same note, one incubating and one eating a fish on the pole:) life is pretty good on the island.

04/26/2017 by baygirl
finally, one incubating and one eating a big fish on nearby pole. also the pair on marsh nest nearby is not around after high tides and 2 days of rain. I assume the nest was flooded. I hope they move elsewhere.

04/24/2017 by baygirl
the pair at the platform show no signs of incubating and most times I check the platform I see just one in the nest, they are not yet using the perch but seem to prefer the corner boards of the platform. the pair deep in the marsh west of this nest are back to incubating again but we are having few straight days of rain and high water so will see what happens to them.

04/18/2017 by baygirl
one on the nest today. the nearby marsh pair seem to have gotten flooded off their marsh nest and they were on 2 2X4's.

04/17/2017 by baygirl
There is another osprey pair attempting to nest directly on the marsh on the same island as this pair, but they are using a sign post to the west and nesting under it. Their presence is causing some territorial disputes but otherwise the Cliffs island pair seem to be adding to the nest. I do not see them copulate or use the nest perch. this may not be the original pair, perhaps that pair is the pair deep in the marsh.

04/10/2017 by baygirl
I am seeing one osprey at the nest daily, usually on a corner board of the platform and the second osprey sits on a nearby posted sign post. very little activity otherwise.

04/07/2017 by baygirl
the platform ospreys were present and after a few days of flooding I could see the marsh ospreys still on the nest and possibly incubating!

04/04/2017 by baygirl
This is a little disconcerting- now there is a second osprey pair building a nest directly in the marsh on this island. They are busy building near a posted sign on the far north/west side of this very low and popular osprey island. I have seen extra pairs do this in years past and of course they get swamped. But I can not be certain the pair in the marsh isn't the same pair that was on the duck blind in 2016! Without color banding we can never be sure who is where! So now there is a pair on the platform and one in the marsh. Some scuffling over air space daily too.

04/02/2017 by baygirl
Both birds at nest today, one on perch and one in nest

03/28/2017 by baygirl
The pair is officially on the platform!!! I watched them yesterday and did see 2 osprey on the near-by guard poles the pair used last season but waited to confirm they have chosen the new platform and today they were on it for some time and came and went to the poles they like on the marsh edge at the main channel into Beach Cove. Happy to see them no longer on the ground!! They are now named Dixie and Cliff after the original landowners.

03/21/2017 by baygirl
First day I see an osprey on the new platform! one osprey perched on the platform t-perch at noon! the hunter took the old duck blind away sometime in late Feb so the returning osprey pair should have a much safer summer nesting

10/26/2016 by baygirl
Here is the story of the duck blind nest: I only seriously began monitoring the nest mid season after I was certain it was active. I believe the adult pair re-nested because they were building up a substantial nest on an old duck blind frame and they were directly in the marsh at high water line. Certainly they had been washed out a few times at this location! A bad storm came through the area 9-3-16 and I watched nervously as the lone chick was exercising its wings and helicoptering at the nest but still not fledging with high water at the nest line. 9-4-16 during the storm with white caps licking the nest the chick finally fledged in front of my eyes. Relief!!! I continued to check the family and 9-18-16 all 3 were near the nest. They perched on old private property signs around the island with the fledgling usually on the nest eating or crying. 9-19-18 was the last day I saw the fledgling. It can be hard to track young osprey when their nest sites are in barren marsh areas as they must leave the area for sheltering. The last time I saw the adult male was 9-23-16 when he was sitting on his favorite sign perch. 2 weeks from fledging is a short period for a young osprey to be independent but with such late nesting this may well be the norm and a risk for late fledgers. 9-30-16 high water destroyed what was left of the nest and now just a single wood piece and few feet of fencing are all that remain of the duck blind just like in years past. We got permission from the land owner and 10-26-16 we erected an osprey platform approx. 100 feet from the duck blind. Landowner has requested the hunter remove the duck blind frame for the 2017 osprey nesting season to hasten the pairs acceptance of the 8ft and safe new nesting platform. stay tuned :)
