One of my favorite things about working with the NJ Eagle Project is when we receive resighting’s of New Jersey banded eagles. Especially when that eagle is in a pair and nesting. One eagle that we’ve been following over the years, is fondly named “Jersey Girl” due to her NJ origins. She was reported to us in 2014 by Linda Oughton, who has been keeping track of her and her mate since 2010.

Jersey Girl and her mate nest in Montgomery County, Pennsylvania. She was one of three chicks banded May 10th 2004 at the Hopewell West, nest which is located in Cumberland County along the Cohansey River. She was banded with green band B-64. That means that this May “Jersey Girl” will be twenty years old!

Since 2010 the pair has successfully raised and fledged a total of 20 young eagles. The pair is not yet incubating this season and Linda reports that they usually start on Valentine’s Day. The pair is well loved by neighbors and people who walk along the Perkiomen Creek, where the pair often fishes.

It’s so wonderful to know that an eagle I helped band almost 20 years ago has survived and raised 20 chicks of her own.

Emmy Casper, Wildlife Biologist

Emmy grew up on the Jersey Shore, where she developed a strong passion for coastal wildlife conservation. In 2020 she joined CWF as a beach-nesting bird technician and spent three seasons monitoring populations of piping plovers, American oystercatchers, and colonial bird species at Edwin B. Forsythe National Wildlife Refuge. During her third season, she served as the crew leader and helped lead the first official season of bird monitoring on Horseshoe Island. Since joining the full-time staff in 2022, Emmy has traded the Atlantic Coast for the Delaware Bayshore, where she manages CWF’s new American oystercatcher and salt marsh restoration projects. She holds a B.S. and an M.S. in Biology from Fordham University, where she conducted her thesis on the molecular analysis of shorebird diet during spring migration in Jamaica Bay.

What’s your favorite species and why?

It’s almost impossible to choose, but piping plovers are so special to me. They jump-started my career in conservation, and their resilience in the face of many challenges inspires me to persevere in my own life.

What’s the most surprising or unusual thing that has happened to you while doing field work?

I was pretty flabbergasted when a piping plover pair laid a seven-egg nest during my first field season at Holgate. The pair’s original four-egg nest had been flooded, so we re-assembled it with the hope that the birds would resume incubating the eggs. Instead, the pair decided to lay three new eggs in the same nest! Unfortunately, the eggs were depredated before they could hatch, but I think a brood with 7+ chicks would have been a sight to behold.

2023 NJ Bald Eagle Project Report

The NJDEP Fish & Wildlife’s Endangered and Nongame Species Program and Conserve Wildlife Foundation of New Jersey have published the New Jersey Bald Eagle Project, 2023. The NJ eagle population continues to thrive. During the 2023 nesting season, 286 nest sites were monitored of these 255 pairs were active (laid eggs). This is a slight increase of 5 active nests from 2022. This season 309 young eagles were documented to have fledged, this number is a down from 2022’s high of 335 young fledged. The productivity rate of 1.28 young per active nest is above the 1.0 young per nest needed for population maintenance.

Fifty-four nest failed to fledge young this season, this means that the pair laid eggs, but the eggs failed to hatch or the chicks did not make it to fledging. There could be many reasons for nest failure including weather events, nest/tree collapse, disturbance by humans or intruder eagles. The NJ eagle population is doing well but they still need monitoring and protection. There is constant pressure for development in NJ and if we don’t know about a nest we can’t help to protect it. Eagles are nesting in all 21 NJ counties, from remote marshes in southern New Jersey to suburban neighborhoods. How the ENSP and CWF protects these nests is on a nest by nest basis. We couldn’t do this without the dedicated group of 150 NJ Eagle Project volunteers who not only monitor the eagle nests, but help minimize disturbance to nests by educating the public about NJ’s eagle population.

The 2024 NJ Bald Eagle season is underway with eight pairs currently incubating. A great way to see what goes on in an eagles nest is to watch the Duke Farms eagle cam. The female should be laying the first egg any day now.

Celebrating 50 Years of the Endangered Species Act

Posted on January 2, 2024 by Rachel McGovern

by Meaghan Lyon, Wildlife Biologist

This year, we celebrate fifty years of one of the most critical conservation laws in the United States. On December 28^th, 1973 the Endangered Species Act (ESA) was passed by Congress. The ESA has prevented 99% of all fish, wildlife, and plants under its protection from going extinct – an incredible feat. Scientists estimate more than 200 at risk species would have gone extinct if not for the development of the ESA. The ESA provides a legal framework to conserve and protect listed species and has safeguarded the biodiversity across the nation, supported the recovery of imperiled species, and conserved the critical habitats they depend on.

Piping plovers are just one at-risk species listed under the ESA.

Currently there are over 1,600 endangered and threatened species listed under the ESA in the United States. Once a species is listed, a full range of protections available under the ESA goes into effect, including prohibitions on killing, harming, or otherwise “taking” a species. To see a complete list of listed vertebrates and invertebrates click the button below:

Listed Species

The ESA is fundamental to our work at Conserve Wildlife Foundation of New Jersey and has allowed us to be better ambassadors for New Jersey’s threatened and endangered wildlife.

Band Resighting Sheds New Light on Delaware Bay Oystercatcher Population

Posted on December 14, 2023 by Rachel McGovern

When CWF began monitoring American oystercatchers nesting on the Delaware Bay this past spring, we also set out to place field-readable bands on as many oystercatcher adults and chicks as logistically possible. Band resights allow biologists to collect a wealth of information about site fidelity, habitat use, dispersal, and migration, especially when data is collected over many years. Since the Delaware Bay population of oystercatchers was previously unmonitored, we have a lot to learn about their life histories and how they may differ from other oystercatchers in the state, if at all. Where are these birds staging and wintering? Do breeding adults return to the same mates and nesting locations each year? Where do fledged chicks disperse, and will they return to their natal grounds on the Delaware Bay to breed upon reaching sexual maturity? Banding efforts, combined with resight data reported by biologists, dedicated volunteers, and the general public will help answer these questions (and more) as we increase the number of marked individuals on the Bayshore.

The color of the field-reable bands on the upper legs represents which state the bird was banded in (New Jersey and New York use orange), while the alphanumeric code on the band is unique to the individual bird. All handling of birds is conducted by trained individuals under proper permits.

New Jersey’s Beach Nesting Birds Struggle in 2023

Posted on December 11, 2023 by Rachel McGovern

by Todd Pover, Senior Wildlife Biologist

This year was an especially challenging one for beach nesting birds in New Jersey. Most of the species fared poorly on a statewide basis, and even though they can withstand periodic down years, several trends are worrisome to biologists and wildlife managers.

The state’s piping plover breeding population remained the same as last year with 118 pairs, which is also about the same as the long-term average since federal listing. However, productivity was just 0.53 chicks fledged per pair, the second lowest since federal listing and well below the levels believed necessary to grow the population. Of particular concern, productivity has been low for three consecutive years after a number of years of above average success. Productivity is one of the main drivers of population (up or down) and small populations are especially sensitive to even small changes, so it is expected that the population is likely to drop over the next few years, further stagnating plover recovery in the state.

Meanwhile, there was a record number (53) of breeding pairs of piping plovers at Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, that is monitored by CWF through a cooperative agreement with the Refuge. This positive trend, almost a four-fold increase has occurred since Superstorm Sandy enhanced the habitat for plovers at the site, has been an ongoing highlight for the state in recent years. Nonetheless, it has not been accompanied by similar increases elsewhere in the state, so it has not led to any statewide recovery. Productivity for the large concentration of piping plovers at Holgate was above the statewide average in 2023 but the lowest level over the past decade, so it was also a down year for this site, where expectations typically run high that it will help boost statewide productivity.

NJ Eagle Cams: Ready For The 2024 Nesting Season

Three Bridges Eagle Cam

The Three Bridges eagle cam went live for the 2024 nesting season on December 1st. A pair of eagles made an appearance that morning. The Three Bridges nesting platform was used by eagles in 2021, when they successfully raised two young. During the 2022 and 2023 nesting seasons, the pair were seen at the nest platform but ended up using a nest in a tree. We will see if the pair decides to use the nest platform this season. For now we believe that the Three Bridges pairs territory is both the nest tree and platform. As the numbers of nesting Bald Eagles continues to increase New Jersey there is the possibility that a second eagle pair could nest at the platform. Last nesting season there was lots of eagle action at the tower, eagles of all ages stopped by along with many different avian species. A pair of Osprey’s took interest in the nest platform but didn’t end up laying eggs. An American Kestrel perched at the platform on the first day the cam was live. It’ll be interesting to see what activity occurs at the tower this season.

“Howls for Owls” Draws Wildlife Fans to Screamin’ Hill Brewery

CWF’s “Howls for Owls” event at Screamin’ Hill Brewery in Cream Ridge, New Jersey was certainly among our most fun fall activities. Owl enthusiasts flocked to this 170-acre farm for an evening of family-friendly activities in celebration of barn owls. Children and adults alike enjoyed dissecting owl pellets, creating owl masks, making adorable pinecone owls, and participating in three rounds of owl-themed trivia. Many attendees even came dressed in owl costumes!

Activities were designed to be fun and to teach attendees about owl adaptations. Owl pellet dissection was one of the most popular things to do. Children and their parents often worked together to extract all the bones found within a pellet and figure out what the owl had consumed.

Kids also made special owl masks with tubes around the eyes to mimic the oblong shape of an owl’s eye. Owl eyes are fixed in place and shaped more like a doorknob or tube than a sphere. When the mask is on, kids discover that they can only see in front of them and must rotate their heads around to look from side to side- just like an owl. Because owls cannot move their eyes, they are adapted to turn their head about 270 degrees around!

“Howls for Owls” had activities for everyone! Crafts, trivia, owl pellet dissection, and other activities kept visitors busy.

Expanding CWF’s Turtle Portfolio

Etiquette tells us that we shouldn’t have a favorite child. I sometimes wonder if the same rules apply to biologists with regard to our study species. If so, my manners fall woefully short, at least where reptiles are concerned.

Conserve Wildlife Foundation has been partnering with the United States Fish and Wildlife Service (USFWS) on bog turtle conservation initiatives for years. We do this using a multi-faceted approach. We connect landowners with qualifying habitat with federal funding opportunities and technical support that can preserve and restore significant wetlands. We assist the state and nonprofit partners with visual surveys to better understand the status of historic populations. Finally, we suit up with USFWS personnel each fall and winter to remove invasive species and woody vegetation that are shading out nesting spots, rendering bogs and fens inhospitable to turtles. We applied to continue this work for the next few years but decided to shake things up a bit by adding in tasks targeting the protection of the bog turtle’s closest living relative… the wood turtle, a state threatened species that is currently under consideration for federal listing.

Birds and Powerlines

Posted on November 14, 2023 by vinyldev

Larissa Smith: CWF Senior Biologist,

Nesting pair of eagles near Atlantic City@ Bill Reinert

Last week I attended the APLIC (Avian Powerline Interaction Committee) workshop hosted by PSE&G. APLIC is a group that leads the electric utility industry in protecting avian resources while enhancing reliable energy delivery. We all use electricity and power lines are needed to distribute the power to where it’s needed. Powerlines and transmission towers have become a normal part of the landscape and we don’t pay much attention until our power goes out. All different species of birds, from bald eagles to starlings, interact with powerlines, poles and towers daily, including perching and nesting on them.

With these interactions come issues, birds can be injured or die from electrocution and collisions which can cause power outages. Nests on poles and transmission towers can create problems with outages and fires as well as risk to chicks or adults. One part of my job is keep track of all reported injured or dead bald eagles in New Jersey. In 2023 there have been fifteen confirmed eagle electrocutions. Any recoveries that are a suspected electrocution or collision with a powerline are reported to the appropriate utility company. CWF and the NJ ENSP have a good relationship with the Utility companies in New Jersey. Each utility company has biologists that work on environmental issues including avian. There are a whole set of issues that they need to be taken into consideration when deciding how best to minimize negative avian interactions. The solutions require time, money and often scheduled power outages. When an area of lines or poles are identified as a risk for bird electrocution/collision, they are made as avian safe as possible. When new distribution lines are rebuilt, avian issues are taken into consideration and the appropriate measures are implemented.

There are quite a few bald eagles and ospreys that nest on poles and transmission towers throughout New Jersey. Most of these nests don’t cause problems, but if they need to be removed, the utility company works to obtain the proper permits and replace the nest with a new nesting structure in close vicinity. One example is the Three Bridges eagle nest. PSE&G needed to replace the entire distribution line where an eagle pair had been nesting on one of the towers for years. After much planning and coordination the nest was removed and placed on a nest platform installed on one of the new towers.

I certainly learned a lot at the workshop and gained a new appreciation for everything that goes into keeping our electricity flowing at the flick of a switch and making sure that avian species stay safe at the same time.
