Three Bridges Eagle Cam
This project is a partnership between multiple organizations to determine the effects of upgrading electrical transmission equipment on nesting bald eagles.
Bald eagles have made an inspiring recovery against overwhelming odds in New Jersey and across the eastern United States. From just a single nesting pair at a failing nest through the early 1980s, eagles have rebounded to over 300 pairs in 2020!
The return of our national symbol has been cheered by New Jerseyans young and old. One site that has been a local favorite has been found at Three Bridges, a community in Readington Township in Hunterdon County. Eagles have nested on top of an electric transmission tower since 2015 and have successfully raised 14 young.
The line of towers was replaced by monopoles, PSE&G worked with Conserve Wildlife Foundation, NJDFW Endangered and Nongame Species Program, and US Fish and Wildlife Service to ensure that the Three Bridges eagles would have every opportunity to continue nesting here. PSE&G designed and installed a nest platform on the new monopole and placed the original nest on the platform once it was erected. The pair returned to the tower and used the new nesting platform in Feb. 2020. The pair raised two young that were banded, H/04 & H/05. The eagle cam was fixed at the time of banding. Both young fledged the end of June, but H/05 was found grounded July 4th. He was taken to The Raptor Trust for rehabilitation and after healing, he was released back at the nest site.

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.

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.

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".
