NJ Bald Eagle Nesting Season Underway
by: CWF Senior Biologist, Larissa Smith
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.
