To help reduce disturbance to young bald eagles we are using satellite transmitters to identify and protect communal roost sites.
Immature bald eagles do not acquire the typical white head and tail until they are four to five years of age.
Bald Eagle Project
We help manage and protect bald eagles to ensure their long term survival. In 2020, there were 248 pairs of bald eagles monitored in New Jersey. 220 of these nests were active (laid eggs) and produced 307 young.
In the 1970s and early 80s there was only one lonely bald eagle nest in New Jersey. With the banning of DDT, federal and state protections, and a huge number of hours invested by volunteers of the Bald Eagle Project, eagles numbers have soared to the triple digits in our state.
As eagle numbers rebounded, so did the demands to monitor nests. Almost every nest in New Jersey is closely monitored by a dedicated volunteer who visits the nest throughout the entire season to help biologists keep track of their attempt at nesting. They observe nesting behavior to determine egg laying, hatching, and fledge dates.
The Bald Eagle project would not be possible without these dedicated volunteers or our state and corporate partners. CWF biologists work closely with their counterparts at the Endangered and Nongame Species Program and corporate partners like Wakefern/Shoprite Stores and P&G provide crucial financial and outreach resources to help keep bald eagles soaring above New Jersey.
Historically, New Jersey was once home to more than 20 pairs of nesting Bald eagles (Haliaeetus leucocephalus). As a result of the use of the pesticide DDT, the number of nesting pairs of Bald eagles in the state declined to only one by 1970 and remained at one into the early 1980's. Use of DDT was banned in New Jersey in 1968 and federally in 1972 after the book "Silent Spring" by Rachel Carson was published in the early 1960s. Her book highlighted the concern of using agricultural synthetic pesticides on a wide spread basis and started the modern day environmental movement. The ban of DDT combined with early restoration efforts by biologists within the NJ Division of Fish and Wildlife, Endangered and Nongame Species Program (ENSP) has led to the successful re-establishment of them in New Jersey, from only one active nest in 1982 to 220 active nests in 2020.
Today, CWF and ENSP biologists work together to manage and reduce disturbance in eagle habitats, especially around nest sites. Eagles are very sensitive to human disturbance and will abandon their nest sites if people encroach on the area during the nesting season, which begins in January and lasts until July. Education and established viewing areas are important in minimizing disturbance, as are the efforts of project volunteers, who are crucial to their successful nesting attempts each year.
In addition to protecting nest sites, biologists also work to protect suitable habitat in a variety of ways, including working with landowners, land acquisition experts, and through the state's land use regulations.
We also work very closely with power generation and service providers to reduce strikes and electrocutions of bald eagles. To help reduce these interactions with power lines we encourage the public, through outreach and education initiatives, to report birds who they believe were electrocuted or impacted a wire. We then gather that information and then report it to utility companies so that they can make alterations to their equipment to reduce chances of such forms of injury or mortality of bald eagles and other large birds.
To help raise awareness for nesting bald eagles, in partnership with Duke Farms, we host a live streaming nest camera that is situated above an eagle nest inside the Duke Farms estate in Hillsborough, New Jersey.
Protecting Bald Eagle Communal Roost sites
Conserve Wildlife Foundation, in partnership with the NJ Division of Fish and Wildlife, Endangered and Nongame Species Program, have been actively tracking 2+ eagles who are outfitted with GPS transmitters. The data collected from this tracking project is being used to help identify and protect communal roost sites. Communal roosts for eagles play a significant role in the life cycle of non-breeding, sub-adult eagles. These sites are protected under a "disturb" clause of the federal Bald and Golden Eagle Protection Act (16 U.S.C. 668-668c); however, little is known about how and where these young eagles roost. Disturb means "to agitate or bother a bald or golden eagle to a degree that causes, or is likely to cause, based on the best scientific information available, (1) injury to an eagle, (2) a decrease in its productivity, by substantially interfering with normal breeding, feeding, or sheltering behavior, or (3) nest abandonment, by substantially interfering with normal breeding, feeding, or sheltering behavior.”
To help protect sub-adult eagles from human disturbance within these communal roost sites, we began tracking young eagles to study their movements. To view the movements of these birds, please click on the link below to view the location of these birds.
