Photos from the Field

by Ben Wurst / Senior Wildlife Biologist

There aren’t many times when you get to climb to the roof of a courthouse in a major metropolitan area. Except if you’re a raptor biologist! We recently joined NJ Fish & Wildlife’s Chief of the Endangered and Nongame Species Program, Kathy Clark and Union County staff and guests to band the four young falcons produced at a nest atop the Union County Courthouse, home to the Union County Falcon Cam.

Updates from the Field: American Oystercatcher Monitoring on the Delaware Bay

by Emmy Casper, Wildlife Biologist

Welcome back to the second season of American Oystercatcher monitoring on New Jersey’s Delaware Bay beaches! CWF, and our partners at the Wetlands Institute and USFWS, have returned to the Bayshore to continue our research project funded by the National Fish and Wildlife Foundation (NFWF). Last year, the CWF-led team surveyed 29 miles of Bayshore beaches, monitored 19 nesting pairs, banded seven adults and four chicks, and conducted invasive species removal. This year, we’re excited to build on that progress and learn more about this previously understudied oystercatcher population.

This American oystercatcher pair nested in a horseshoe crab shell, perfectly embodying the vibe of the Delaware Bayshore.

Third Grade Students Explore the Fascinating World of Peregrine Falcons

by Rachel McGovern, Director of Education

Peregrine falcons are fascinating to learn about—they are swift, fierce, and intelligent birds. They are a joy to teach about, too! CWF is fortunate to have the opportunity to teach about these amazing birds of prey with students in Linden Public Schools, due to the generous support from Phillips 66 Bayway Refinery.

Each year, CWF visits every third-grade classroom in the Linden Public School District to deliver in-depth lessons about peregrine falcons. These lessons delve into the life history of peregrines, the reason for their decline, and how they are recovering today. Students explore how these falcons have adapted to modern-day landscapes by nesting on manmade structures rather than exclusively choosing their traditional cliffside sites. For city-dwelling students, it’s a revelation to discover that these endangered raptors thrive in environments like their own.

Central to this educational initiative is the Union County Falcon Cam– a live camera on a falcon nest located just a couple miles from Linden’s elementary schools. This camera has been in operation since 2016. It is run in cooperation with Union County and the New Jersey Department of Environmental Protection. A live feed brings the viewer into a nest on the roof of the Union County Courthouse where Frida and Mango, the current pair at this nest, raise young each year. Students learn about the history of the camera and check in with the birds during their lesson. Teachers are also encouraged to check in with the falcons regularly for students to watch them raise their young.

Expanding Conservation with Biotics

by Robert Criollo and Daniel Turcios, GIS Program Managers

In the world of Biotics, it all starts with one upload. An observer can come across the species wandering the forests of New Jersey and snap a photo of it. From there, they upload it to the New Jersey Wildlife Tracker

A few tracked species are: Eastern Box Turtles, Bobcats, Peregrine Falcons, Red Knots, and Pine Barrens Treefrog.

Exploring New Jersey’s Amphibian Migrations

by Leah Wells, Wildlife Biologist

Wood Frogs

 On rainy spring evenings, have you ever encountered large numbers of salamanders and frogs crossing the road? Do you ever wonder where they came from and where they are going? New Jersey’s forests are home to a group of amphibians that breed in small, temporary wetlands called vernal pools. Within northern New Jersey, this group includes wood frogs, spotted salamanders, and Jefferson salamanders. 

These salamanders are elusive, often concealed under foliage, moss, or in burrows created by small creatures.  They belong to the Ambystomatidae family, earning the nickname “mole salamander” due to their subterranean tendencies. Feeding primarily at night on various invertebrates like earthworms and insects, they, along with wood frogs, play crucial roles in forest ecosystems as vital links in the food chain and are indicators of ecosystem health. Emerging from winter hibernation during rainy nights in late winter and early spring, they embark on journeys to vernal pools for mating and egg-laying, marking the onset of the amphibian migration.

Encouraging Development for Tiger Salamanders

By Christine Healy, Wildlife Biologist

In today’s world, it’s pretty difficult to think of a species that scientists are not concerned about in the face of climate change. The reasons are many and diverse, but in a state where 42% of municipalities are considered “coastal”, it comes as no surprise that sea level rise (SLR) is a big threat here- both to people and wildlife. When the average person imagines which species are most likely to be impacted by SLR, it’s likely that beach nesters, including piping plovers, immediately come to mind. Afterall, they occupy the same environments that recreationalists are worried about losing. Valid point- but they are not the only ones. Eastern tiger salamanders, one of New Jersey’s rarest amphibians, also make the list. 

Like our other mole salamanders (spotted, blue-spotted, marbled, and Jefferson), Eastern tiger salamanders require access to temporary wetlands, called vernal pools, to successfully breed. The ephemeral nature of these water bodies is critical because it eliminates fish as potential egg predators and thus increases larval survival. While these salamanders spend much of the year in forested landscapes, adults return annually to their natal pools (in most cases) to reproduce. High fidelity to these sites can put these amphibians in danger if development occurs within their migration corridors or changes transpire within the pools themselves.

Highlights of a Recent Mammal Inventory

by Meaghan Lyon, Wildlife Biologist

In the spring and summer of 2023, CWF set up over 100 field cameras in a variety of habitats along mammal travel paths at the Joint Base in Lakehurst. The study captured a glimpse of what wildlife does when they think no one is watching.

To start, here is an abbreviated species list of most of the wildlife captured on camera. We were not surprised to find that nearly 80% of our captures were of white-tailed deer! Unfortunately, no captures of black bears have been reported in the area in previous years. Check out some of the captures below!

  • White-tailed deer
  • Red fox
  • Grey fox
  • Coyote
  • Striped skunk
  • Opossum
  • Beaver
  • Groundhog
  • Eastern grey squirrel
  • American red squirrel
  • Southern flying squirrel
  • Raccoon
  • Eastern cottontail rabbit
  • Mice species
  • Domestic cat
  • Great blue heron
  • Wild Turkey
  • Owl species
  • Songbird species

Nor’easter and Prey Shortage Impacts Nesting Ospreys in 2023

by Ben Wurst / Senior Wildlife Biologist

In coastal New Jersey, during spring and summer the recovery of ospreys is apparent. They grace the skies of most ocean front beaches from Sandy Hook to Cape May in search of prey. Their nests line our shorelines and can be found in a variety of nest structures. Today there are over 800 pairs of ospreys who nest all across New Jersey. Results from the 2023 nesting season illustrate how the osprey population continues to grow but with reduced reproductive success due to extremes in weather and reduced prey availability.

“Jersey Girl”: 20 Years and Going Strong

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 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.
