Results from 2019 Osprey Nest Surveys highlight another productive year.

Surveys of osprey nests in New Jersey have occurred annually for the past forty five years. They are conducted to help determine the overall size and health of the population. The first aerial survey over Barnegat Bay counted only five active nests. Ten years earlier there had been over 50. The combined effects of DDT and habitat loss had taken their toll. No osprey nests were productive and the population at risk of being extirpated from the state.
“In 1974 there were only five active osprey nests on Barnegat Bay. Today there are approximately one hundred and fifty.”
After ospreys were listed as endangered an innovative effort to transplant viable eggs from the Chesapeake Bay to Barnegat Bay began. In addition, to help replace natural nest sites that were lost to development, man-made nest platforms were designed and installed away from human disturbance. Slowly osprey pairs became productive thanks to the die hard effort of State biologists like Pete McLain, Kathy Clark and many volunteers and partners. It’s encouraging for us to look back to see how far we’ve come in the statewide recovery of ospreys in New Jersey.

Conserve Wildlife Foundation has been a partner in the reTURN the Favor (RTF) program since its establishment in 2013. This multi-partner program organizes a large group of trained and dedicated volunteers who collectively spend thousands of hours covering miles of Delaware Bay beaches to rescue stranded horseshoe crabs.
This year RTF was honored with a New Jersey’s Governor’s Environmental Excellence Award, New Jersey’s premier awards program for recognizing outstanding environmental performance, programs and projects throughout the state, in the Healthy Ecosystems & Habitats Category.

Amphibians are among the most vulnerable and rapidly declining wildlife groups in the world. Do you want to get out in the field and help frogs here in New Jersey?

This past summer I was lucky enough to work with Conserve Wildlife Foundation as a volunteer student intern. I worked alongside Ben Wurst, CWF’s Habitat Program Manager, helping with the New Jersey Osprey Project. My internship consisted of assisting with osprey surveys, banding young, and recording data so that we can estimate the health of the population in New Jersey.

Conserve Wildlife Foundation of NJ in partnership with the
NJ Division of Fish and Wildlife’s Endangered & Nongame Species Program, is
releasing results of the 2019 NJ Bald Eagle nesting season.
2019 was a record year for NJ eagles with the highest number
of active nests and young fledged in the history of the project. This year, 238 eagle nests were monitored, of
which 189 were active (laid eggs) and 248 young fledged. This is the highest number of fledges ever,
surpassing the previous high of 216 in 2016.

We owe the incredible amount of information about NJ eagle success
to the NJ Eagle Project nest watchers. An
extremely dedicated group of approximately 85 volunteers monitor nests during
the season, recording the important dates and watching for possible issues at
nest sites.
This season two eagle cams were available to watch on the CWF website: one at Duke Farms and another at Mercer County Parks. The Duke Farms nest produced two chicks, and one was outfitted with a satellite transmitter; the movements of this eagle are on CWF’s Eagletrax website .
More details on the 2019 nesting season will be available in
the annual eagle report to be posted by December. The report will include individual nest data, state
totals, and eagle recoveries and resightings.
CWF partners with PSEG, the Mercer County Park Commission, Mercer County Wildlife Center, and Wildlife Center Friends and Duke Farms to protect bald eagles in New Jersey. Thank you to the Wakefern Food Corp./ShopRite Markets, Wells Fargo, Chemours and the American Eagle Foundation for additional eagle program funding.
There is a hole in my heart this week after hearing about the passing of my friend Pete Bacinski. I met Pete many years ago when he used to lead NJ Audubon Sussex County weekends jointly with the Weis Ecology Center.
The Conserve Wildlife Foundation of NJ in partnership with the NJ Division of Fish and Wildlife, Endangered and Nongame Species Program, has released the 2018 NJ Bald Eagle Project Report.
“Two hundred-four nest sites were monitored during the nesting season, of which 185 were documented to be active (with eggs) and 19 were territorial or housekeeping pairs. Thirty new eagle pairs were found this season, 20 in the south, nine in central and one in the north. One hundred-twenty-one nests (66%) of the 182 known-outcome nests produced 172 young, for a productivity rate of 0.94 young per active/known-outcome nest. The failure rate was well above average with 61 nests (33%) failing to produce. The Delaware Bay region remained the state’s eagle stronghold, with roughly half of nests located in Cumberland and Salem counties and the bayside of Cape May County.”
The number of active nests has increased while the number of young eagles fledged has decreased since a high of 216 young fledged in 2016. During the 2018 eagle nesting season there was an abundance of cold, wet, windy and snowy weather which was the cause for a portion of the nest failures. As the eagle population increases, there are more eagles competing for territories. This can also be a contributing factor in nest failures. NJ is still in the range of 0.9 to 1.1 young per nest which is needed for population maintenance with a productivity rate of 0.94 young per known-outcome/active nest in 2018. The 2018 NJ Eagle Project Report has all the details on the project including telemetry, re-sightings and recoveries.
The success of the eagle project is due to the tremendous dedication of the NJ Eagle Project Volunteers. They monitor the nests in all types of conditions and education people about the eagles with enthusiasm.
On a brisk November morning, a couple dedicated NJ Osprey Project volunteers joined myself and CWF Biologist Larissa Smith to install an osprey platform on the coastal saltmarsh of New Jersey. The new platform was installed to replace a very old and unstable platform that fell this summer. The new structure is more than twice the size of the old one and will give the nesting pair, who return in the spring, a much more resilient nest site. As you can see from the video above, it takes a bit of strength to raise up a 16′ tall wood nest platform. We decided to slow it down when WCC Volunteer, Wayne R. gives it a final push.
