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.

A Visit to Tri-State Bird Rescue and Research

Thursday, November 17th, 2022

by Meaghan Lyon, Wildlife Biologist

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.

Fact or Myth? The Ecological Importance of Bats

Tuesday, November 1st, 2022

by Meaghan Lyon, Wildlife Biologist

It’s that time of year again, the days are getting shorter, temperatures are dropping, and creatures of the night are lurking behind shadowy corners. As Halloween approaches one animal comes to the forefront of everyone’s mind – bats.

Bats have been misunderstood by humans for many years and are still among the most persecuted animals on earth. In many parts of the world, bats are killed due to fear or harmful myths that make them seem scary or even dangerous. However, the fact is that bats are one of the most beneficial animals to humans.

Photo Caption: Bats are in the order Chiroptera, meaning “Hand-wing”. This skeleton shows how the wing of bats has a very similar structure to that of the human hand.

Leave The Leaves This Fall

Once leaves fall to the ground, leave them be! Deciding not to rake, blow, and dispose of your leaves not only benefits native wildlife but provides nourishment to your garden and lawn. 


A Kestrel Story

Friday, August 26th, 2022

Diane Cook, CWF volunteer

As a volunteer for Conserve Wildlife Foundation of NJ and NJ’s Wildlife Conservation Corps I monitor bald eagle, osprey, and kestrel nests for the state. Kestrel monitoring is new to me this year. They are North
America’s smallest falcon. I enjoy watching them hunt, hovering over the grasslands
and open fields. Monitors watch and record milestones of the nesting season. Fledge
Day is the end of our season and what we hope to witness.
Friday – I knew the chicks would be fledging soon, and hoped I had not missed it. I sat in
my vehicle and watched for just over 3 hours! I could hear noise from inside the box as
wings were being flapped and exercised. For the longest time, I thought one had
already fledged since I was just seeing one perched in the box opening.
