Nesting Diaries

03/29/2023 by UD Marine Ops
There has been several osprey flying around this nest each day I have walked by. A pair has claimed it and are nest building.

03/23/2023 by UD Marine Ops
There is activity at this nest this week also. I don't see this nest as often, so can't confirm if it is the final pair yet. The sky is full of Osprey this week which is great.

03/23/2023 by UD Marine Ops
A pair has been seen at this nest most mornings since 3/17. Welcome back!

08/23/2022 by UD Marine Ops
This nest has had no activity in several weeks.

06/14/2022 by UD Marine Ops
This pair and nest is doing well. One large nestling is being tended to.

06/03/2022 by UD Marine Ops
Pair behavior at this nest is also indicative of the eggs hatching recently. I will keep an eye on it.

05/06/2022 by UD Marine Ops
This pair has remained active and built a nice nest. One can be seen hunkered down over the eggs. A nor easter is coming tonight through the weekend so I'm updating the activity to date.

03/21/2022 by UD Marine Ops
This pair is consistently at the nest in the morning. Nest material is building.

03/16/2022 by UD Marine Ops
Nest material accumulating. Some territorial aerial skirmishes today around the nest.

03/11/2022 by UD Marine Ops
Two Osprey resting on the perches and feeding over the past two days.

03/09/2022 by UD Marine Ops
Male seen perched on post yesterday and today. Seems to be resting.

08/12/2021 by UD Marine Ops
Nest has remained empty the last few days I've walked by.

08/03/2021 by UD Marine Ops
Nest was empty this morning. The young one has fledged.

07/04/2021 by UD Marine Ops
One hatchling maturing well. Photo attached.

06/25/2021 by UD Marine Ops
Parenting activity continues. I have seen one large fledgling the several times I was by this week. There may be another but I am becoming doubtful.

06/16/2021 by UD Marine Ops
The head of a large hatchling (maybe a fledgling now?) was seen today (photo attached). I will keep an eye out for another before logging an entry. I suspect only one survivor due to the size and healthy state of the one seen. Good news to have at least one healthy one this year! Male and female are always seen diligently tending to the young and this nest.

06/11/2021 by UD Marine Ops
There are still two adults tending to the nest so I'm guessing at least some of the nestlings are doing ok. Weather remains a challenge between heat and long periods of rain.

06/07/2021 by baygirl
2 adults at nest, appears to be feeding

06/02/2021 by UD Marine Ops
Two seen in the nest today in tending mode more than incubation so hopefully some hatchlings are in there.

05/30/2021 by baygirl
platform needs a predator guard, many in this area do

05/13/2021 by UD Marine Ops
It has been a chilly week. The few times I drove by a head could be seen so incubation continues.

05/04/2021 by UD Marine Ops
One has been in incubation posture the several times I have viewed this nest over the past two weeks.

04/18/2021 by UD Marine Ops
I walked by a few times this morning. One osprey is in incubation position in the center of the nest.

04/13/2021 by UD Marine Ops
Nest is getting well built up. Pair seen flying around or nesting on several of my walk bys.

03/23/2021 by UD Marine Ops
Occupied for two days now. First day of several Osprey flying and chirping around. One flew by with a nice size fish. Welcome Spring!

08/24/2020 by UD Marine Ops
I haven't seen much activity in this nest lately.

08/07/2020 by UD Marine Ops
I have only seen one in the nest since the tropical storm on 8/4.

07/28/2020 by UD Marine Ops
Two healthy fledglings in and out of the nest. Mom gone already or out feeding herself and resting?

07/20/2020 by UD Marine Ops
I'm pretty sure I have seen two fledglings in the nest. One is larger than the other. Male seems to have moved on a week or so ago.

06/20/2020 by UD Marine Ops
One nestling head in clear view today. Possibly another, but am not sure.

06/17/2020 by UD Marine Ops
Nurturing behavior ongoing.

06/11/2020 by UD Marine Ops
This pair seems to be in parent feeding hatchlings mode, but I have not seen hatchlings yet. They have occupied the nest since early Spring.

03/16/2020 by UD Marine Ops
Note, the structure of this nest was repaired by UD facilities personnel several weeks ago. They replaced the box and put two standard perching bars in. There were no perching bars last year. I will get a photo.

03/16/2020 by UD Marine Ops
Last week a pair was seen daily at the Lewes ball field but none on the UD campus. Today (Monday) two nests were observed with pairs!

02/12/2020 by UD Marine Ops
Male seen resting in nest today. Quite early in the season. Maybe will head north. I'll keep eye out for him. Winter has been too warm.

08/28/2019 by UD Marine Ops
Vacant the few times I saw it the last few days.

08/23/2019 by UD Marine Ops
0-1 the last few days

08/21/2019 by UD Marine Ops
0-1 seen in the nest yesterday and this morning.

08/21/2019 by UD Marine Ops
0-2 seen flying in and out yesterday. One perched this morning.

08/14/2019 by UD Marine Ops
One in the nest most of the time I go by it. Sometimes vacant so it is flying.

08/13/2019 by UD Marine Ops
0830 - one last night at 1730. Vacant this morning.

08/07/2019 by UD Marine Ops
0715 - one on the nest

07/30/2019 by UD Marine Ops
~1015 - Two Osprey in the nest. The hatchling is fully feathered but I have not observed flight yet.

07/23/2019 by UD Marine Ops
Two osprey were in nest the two times I observed yesterday and also this morning. I haven't seen flight yet.

06/28/2019 by UD Marine Ops
~0900 - One relatively small hatchling being well cared for by two adults.

06/25/2019 by UD Marine Ops
1700 - Two adults and the hatchling being well cared for.

06/22/2019 by UD Marine Ops
Around 1300 today one adult and the small hatchling (smallest of all the UD nests I observed today) were active. The second adult arrived a short time later. All look well. The hatchling is small and looking fragile. Hopefully will put on more weight soon.

06/16/2019 by UD Marine Ops
Two adults were there when observed today. Female was feeding one small hatchling. No sign of a second during several minutes of observation.

05/31/2019 by UD Marine Ops
Interesting note. There is a nest very close on the USCG range beacon. Their posture as well indicates hatching.

05/31/2019 by UD Marine Ops
I don't observe this nest as much as #3. Based on the positioning of the adults (similar to #3), I think hatching has occurred.

03/27/2019 by UD Marine Ops
Nesting pair seen and the nest is under renewed building. Today was the first siting of the pair. I drive by 2x/day.
