Bald Eagles are the earliest nesting birds in New Jersey. Two pairs of eagles laid eggs in December of 2022 and those nests have already hatched. Those pairs are the really early “birds”, so far 73 pairs of eagles are incubating (laid eggs). Nest Monitors are keeping an eye on over 300 known eagle territories in NJ, the bulk of which lay their eggs in February to mid-March. Eagles incubate for approximately 35 days before hatching occurs. The female does most of the incubating the male also takes over the incubation duties so the female can go out and hunt. One hundred and fifty nest monitors keep track of the eagle nests and report on incubation. It can be quite difficult to tell when an eagle is in the nest incubating. Sometimes all the nest monitor can see is just the top of the head pop up every now and then. One way to determine incubation at a nest is to witness a “nest exchange”, where the male and female switch incubation duty.

Over the next few months as the eagles incubate and hatch chicks, they are very sensitive to disturbance. Nest Monitors are trained and experienced and only view the nest from a location that doesn’t disturb the eagles. Monitors use high powered scopes and cameras to determine the status of the nest. While it’s always a great sight to see an eagle, please respect them and view from a distance. To see what goes on in an eagles nest close up check out the Duke Farms eagle cam. The pair is currently incubating two eggs and hatching of the first is expected around February 24th. You can also watch a pair of eagles at The Three Bridges eagle cam. They aren’t yet nesting and we’re not sure where they will nest this season, but they have been making frequent appearances at the nest tower.
The results are in! It wasn’t a great year for upland sandpipers at the McGuire Airfield. Numbers of breeding pairs at this location have decreased to an estimated two pairs. Numbers can be variable from year to year so there is still hope for better news in 2023.
Upland sandpipers typically require a minimum of 100 acres for breeding habitat and so large expanses of open, grassy land is a high priority. Over the past five years, long term efforts have been ongoing to complete a large-scale grassland restoration at the McGuire Airfield. So far, roughly 500 acres have been converted to native warm season grasses with another 100 acres to be completed by next spring. Our goal is to help create and maintain grassland bird nesting habitat for Upland sandpipers and other species.
With 2022 coming to a close, Conserve Wildlife Foundation’s staff took a moment to reflect on what they were thankful for this year at work and with regards to New Jersey’s wildlife.
The CWF team (Board and staff) enjoyed a holiday celebration at Flying Fish Brewery.
I’m thankful for New Jersey’s incredible wildlife and my role in protecting so many at-risk species. I owe my greatest appreciation, however, to the dedicated people who carry out and support CWF’s work to strengthen wildlife populations and educate the next generation of environmental stewards. Our Board and staff are truly extraordinary at what they do, and our contributors, volunteers, and partners make all our success stories possible.

In 2014, we began to band osprey nestlings produced at nests within the Barnegat Bay watershed with auxiliary bands. This was an effort which came about from the interest of Jim Verhagen, a LBI resident and wildlife biographer. He wondered why young ospreys were not banded with color, field readable bands, like some endangered raptors, including bald eagles and peregrine falcons. This spawned Project RedBand, an osprey banding and re-sighting project. The goal of the project was to learn more about ospreys when they are alive while engaging coastal residents in their management. Just under 500 young ospreys were banded with red auxiliary bands from 2014-2020 from nests all along the Barnegat Bay estuary.
When CWF biologists encounter an injured bird while doing field work, we usually turn to Tri-State Bird Rescue and Research for help. A recent visit to the Tri-State Bird Rescue and Research facility located in Newark, Delaware provided great insight into the efforts that go into ensuring that injured and oiled birds have a second chance in the wild. Their mission is to provide professional, compassionate rehabilitation to native injured and orphaned wild birds and contaminated wildlife, and to promote their stewardship through education and humane research.
The facility has two programs, the Wild Bird Clinic and Oiled Wildlife Response. With more than 40 years of experience, the Wild Bird Clinic provides expert medical care, housing, and diets to injured, orphaned, and oiled native wild birds.
Inside the Oil Response Center you see large buckets to wash birds and other wildlife. Hoses hang from the ceiling to provide easy access and to avoid hazards.

Since 2018, CWF has partnered with the USFWS New Jersey Field Office in completing summer mist netting surveys for bats in the Pinelands. The goal of these surveys is to capture the federally threatened Northern long-eared bat and track these bats to maternity roosts.
Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, is having another record year for piping plovers. A total of 49 pairs have nested at the site this year, up from 46 pairs in 2021, which was also a record, by far, from the previous high for the site. Since Superstorm Sandy devastated much of the New Jersey coast in October 2012, the number of piping plovers nesting at Holgate has increased fourfold.
Hurricane Ida. Hurricane Irene. Superstorm Sandy. These weather events represent three of the four most devasting storms recorded in New Jersey history. Though data dates back 218 years, all 3 have occurred within the past 11, substantiating concerns over the effect of climate change on tropical cyclone severity. Therefore, taking measures to safeguard communities from devastating floodwaters is more important now than it ever has been. But who said helping people can’t, in turn, help wildlife?
Since 2003 Conserve Wildlife Foundation has been coordinating the Delaware Bay Shorebird Stewards. Shorebird Stewards are posted at the beaches with restricted access during the shorebird season. This is done so that the shorebirds can feed undisturbed on horseshoe crab eggs. The beach restrictions are from May 7th to June 7th. The Delaware Bay is an important stopover for these birds on their way north to their breeding grounds. Stewards educate the public about the need for the beach restrictions. Once most people learn about the connection between the horseshoe crabs and shorebirds, they are more than happy to accept the restrictions. This season there were thirty-one stewards on 10 beaches in Cape May and Cumberland Counties. They are dedicated and on the beaches despite the weather, bugs and sometimes lack of shorebirds. Stewards are on beaches through Monday, so stop by and say “hello”.
Thank you Shorebird Stewards
