Three Bridges Eagle Cam Nesting Season Update Archives / 2021-23

These are updates that were posted during the 2021-2023 nesting seasons on the Three Bridges Eagle Cam webpage.

March 7th 2023 - Last update of the season

There aren’t any eagles nesting on the platform but there has been a lot of activity at the tower.

We think that the Three Bridges pair is using the same nest in a tree that they used in 2022. This season the pair began incubation on February 19th. NJ Eagle Project nest monitors work closely together to monitor the tree nest while also watching the cam and comparing notes. We believe that the tower is in the Three Bridges pairs territory so they do visit it now and then.

The tower is being used by other eagles and raptor species. On February 25th, there was quite a bit of activity. An immature eagle was on the tower with an adult.

At one point another adult buzzes them. Then another immature eagle comes into the nest. We don’t know if this was an “extra” adult or one from the Three Bridges pair.

The closeups of the immatures give a great look at the different plumage immature eagle have until their 5th year, when they get the white head and tail feathers. While plumage on individuals vary these birds are between 2- 3 years of age.

Nest Monitor, Mary Ellen Hill has seen a pair of kestrels on the tower daily. On March first a pair of adults, an immature eagle and a red-tailed hawk all stopped by the platform.

While it is disappointing that the platform isn’t being used for nesting this season, it is still neat to see the birds that do use the tower and platform. As the NJ eagle population continues to increase, at some point in the future there will most likely be a pair that will use this platform for nesting.

February 7th, 2023

The pair were seen spending time at the platform nest in the morning and afternoon today. They copulated and chased an intruder eagle away. There have been no eggs laid at the tree nest so we're still waiting to see where they choose to nest this season.

February 2nd 2023

Today a pair of American Kestrels were seen on the cam copulating. Both of the birds were banded with silver leg bands. In 2012 Kestrels were listed as a NJ Threatened species due to a decline in their population since 2000. Kestrels naturally nest in cavities, but will also nest in man-made nest boxes.

One of the kestrels expelled a pellet as can be seen in the series of two photos below. Pellets are the indigestible materials such as fur, bones and feathers from their prey.

The view from the cam was stunning at sunrise. A kestrel visited the tower as well as an immature eagle.

January 20th, 2023

An adult eagle brought a fish to the nest platform today. We still don't know where the pair will nest. They have been seen at the tree nest they used last season. In 2022 they laid their first egg January 19th. So they should be choosing their nest any day now.

A pair of American Kestrel's perched at the platform today. These are the smallest falcon's in North America with beautiful plumage.

The pair was back at the nest yesterday and the female was seen bringing in a stick.

Today there was more eagle activity at the nest platform. Two eagles were at the platform and buzzed again by a red tailed hawk. The pair then copulated. Nest Monitor Mary Ellen Hill was able to zoom in and get some great closeup views of one of the eagles.

December 27th

Cam viewers witnessed some interesting activity at the nest platform. A pair of eagles was seen on the platform. They were buzzed by a Red-tailed hawk and the pair defended the nest. A pair of eagles has also been seen working on the tree nest that we assumed the Three Bridges pair used last season. Since non of the eagles are banded we can't know 100% that it's one or two pairs. But most likely it is the Three Bridges pair using both the nest tree and platform as their "territory".

This afternoon a Peregrine Falcon visited the tower to eat its lunch.

Eagle nest monitor Mary Ellen Hill reports that she hasn't seen the pair on the nesting platform, but she did see them perched on the arm of the tower December 4th.

The Three Bridges eagle cam was deactivated for the season on March 31st at 5pm.

Thank you to everyone who has supported and viewed this eagle cam!

It looks like the Three Bridges pair has chosen another location to nest this season. The camera still captures some interesting wildlife. On Monday March 7th there was alot of activity at the nest platform; a pair of mating kestrels, an adult and an immature eagle both visited the nest platform. The camera will be turned off the end of March if there continues to be no nesting activity.

February 25th

No eggs have been laid at the nest and the eagles are being seen infrequently. There is a strong possibility that the pair is nesting in another location. Yesterday 2/24/22 an adult eagle was seen on the cam and one was even defending the nest from a red-tailed hawk. If the pair is nesting somewhere else, then they could still consider the tower their territory. We don't know for certain if this eagle was from the 3B pair. We will have to wait and see what happens over the next few weeks.

February 17th

After not being seen on the cam for a week, the pair showed up early this morning. They mated twice and worked on the nest. They were there for a little over an hour. Hopefully we'll see them more over the next few days as they get closer to laying eggs.

February 10th

On Tuesday February 8th the Three Bridges pair brought grass to the nest and mated several times. But were not seen at the nest on Wednesday or Thursday. We are still two weeks out from when they laid eggs in 2021.

January 28

eagle project volunteer Diane Cook, put together this video from earlier today, showing an adult flying and perched at the tower.

The Three Bridges eagle monitors have been kept busy the past few weeks. The pair has made only a few appearances on the nest cam. There is another nest in the area and eagles have been seen at that nest.

We aren't sure if the Three Bridges pair is the pair seen on the second nest or not. The nest monitors report seeing other eagles both adults and immatures in the area. Nest monitor Mary Ellen Hill got this photo of an adult with a pheasant near the second nest.

Last season the Three Bridges pair didn' start incubating until Feb. 24th. If they are on the same schedule this season then we are still a few weeks away from egg laying. Two adults were seen on the eagle cam Jan. 27th.
