Barn Owls (Tyto alba) are one of the most widespread avian species in the world. Despite this impressive distribution, their numbers have been decreasing in parts of their range, and New Jersey is no exception. The barn owl population in New Jersey is in decline due to habitat loss associated with urban sprawl and development of former agricultural lands. Little is known about the Barn Owl population in central New Jersey. Through a grant from the Monmouth Audubon Society, Conserve Wildlife Foundation of New Jersey is partnering with Monmouth County Park System and the New Jersey State Park to construct, install and monitor three barn owl boxes. By providing suitable nest site opportunities we can potentially boost the barn owl population locally within Monmouth County as well as regionally as fledglings disperse to find their own nesting areas.

The first step of the project has been completed. CWF biologist Christine Healy and her Father Jim Healy have constructed three nest boxes that are ready for installation.

Would you like to learn more about the elusive Barn Owl, support the CWF Barn Owl Project and have a fun family night? Join us at Howls for Owls, at the Screamin’ Hill Brewing.

We Hope to see you there. This outdoor event will be cancelled for bad weather, so please stay updated on our website.

When we founded the Great Bay Terrapin Project, our goal was to reduce roadkills of adult female northern diamondback terrapins. This was largely due to personal observations of multiple roadkills during the summer months along roads in Little Egg Harbor Township and past research which accounted for a large number of adults DOR (dead on road). Since 2010, we’ve been able to cut the historic roadkill rate in half, all thanks to our devoted volunteers who patrol area roads and raise awareness for them! This allows adults to grow larger and live longer lives, which helps to ensure their long term survival.

NJ Eagle Project Volunteers monitor nests during the nesting season. Since they spend a lot of time observing the nest and eagles behavior they get to see some pretty interesting things and many of them are able to document with photos. I asked volunteers to send me their three favorite photos from the eagle nesting season. Thank you to all the eagle project volunteers for their dedication

Enjoy the slideshow.

Depending on where you look and who you talk to, the fate of many osprey nests might bring tears to your eyes. Since a nor’easter impacted the coast with strong onshore winds for several days, young ospreys have been dying of starvation in plain sight. Over the past week, several reports of adults who abandoned their nests with young have been received. This year, weather has impacted the availability of fish and outcomes of nests in the Garden State.

This past Monday I joined several partners to release a very special northern diamondback terrapin back into the wild. This adult female terrapin had been illegally collected and sold into the black market pet trade. Over the past couple years we have been working on a plan to get her back the wild.

Each of these partners, including Dr. John Wnek, MATES/Project Terrapin, Kelly Scott, NJ State Park Service, Brian Zarate, NJDEP Fish & Wildlife played an important role in her successful release (you can read about each of their roles in a story by Dr. Wnek below). We gathered in the parking lot of a former marina which CWF & NJDEP Fish & Wildlife converted into suitable nesting habitat for female terrapins. For all of us, I think it’s safe to say that it was bittersweet to see her swim off into the brackish water. She was home.

The Princeton eagle nest collapsed sometime between Friday June 2nd and early Saturday June 3rd. The Princeton pair had two chicks that were ten weeks old and close to fledging. NJ Eagle Project volunteers, Kevin and Karin Buynie monitor this nest and went out as soon as they were notified. When they arrived one chick was perched up in the tree and one was on the ground. The grounded chick was taken to Mercer County Wildlife Center for evaluation. The next day Kevin returned to the nest site and found the second chick now on the ground, so that chick was also captured and taken to MCWC. Both chicks were found to be uninjured and ready to return to the nest. A plan was formed to build a new nest in the tree and renest the two chicks. On June 11th, a group of volunteers and staff from Mercer County Wildlife Center met at the nest site. John Heilferty, retired ENSP Chief, climbed the nest tree and built the nest as volunteers helped to send up the needed materials. Diane Nickerson with the MCWC brought the two chicks, which were banded with Green NJ band H/39 and H/38 and silver federal bands. The chicks were then placed back up in the nest. One of them decided to fledge and the other perched on a branch near the nest. The recently fledged chick did return to the nest that evening and the second chick fledged June 16th. Thank you to Karin and Kevin Buynie, Diane Nickerson and volunteers Daniel and Hope with Mercer County Wildlife, John Heilferty, Kim Korth, and Roger Smith.

In the May 16th blog, Shorebird Stewards On the Bay in May, it’s mentioned that some beaches along the Delaware Bay have restricted access every year from May 7th to June 7th. This is due to the migratory shorebirds that travel thousands of miles and need a place to stop to feed. Our beaches contain excellent food sources to help birds gain weight to continue their journey- horseshoe crab eggs. They are filled
with fat and protein. The Delaware Bay is the largest spawning area for horseshoe crabs in the world!

Now what do the Shorebird Stewards, such as myself, do all day? We monitor our assigned
beaches and educate the public about this incredible phenomenon! My favorite beaches are
Roosevelt Blvd. beach and Cook’s Beach because I see the most active flocks of shorebirds at
these locations.

On a quiet day with not many people to educate, there are many things for us Stewards to do.
Some Stewards read their books, watch movies, listen to music/podcasts, color/paint, take
walks, research, etc. I do all of the above! Since we have a love for these special shorebirds,
most Stewards also birdwatch! It’s a must to bring your binoculars or scope to observe these
beautiful birds. Sometimes, you observe other interesting animals, too!

Another activity to do in the down-time is to flip the spawning Atlantic Horseshoe crabs, Limulus
polyphemus, back onto their legs so they can crawl back into the bay. When the tide rise, these
crabs get overturned by the waves and have no way of returning back to their feet! Personally,
this is my favorite activity to do. When you return after your “crab walk”, you get to see the
tracks of their feet traveling back into the bay where they belong. Below on the left is a picture of
flipped and rescued crabs: the one on the left is a male who decided to bury himself in the sand
to preserve water until the tide comes back in, and the one on the right is a male who decided to
make the trek back into the bay. When the tide comes in, the horseshoe crabs come up
and begin spawning. Pictured below in the middle is an example of how crowded the beaches
get with these creatures! On the right, is a photo of a tagged crab I found, and reported it to
the US Fish and Wildlife Service so that they can collect data on the tagged crabs.

You can also get involved with helping these critters! “Return the Favor” is an organization
dedicated to conducting beach walks to flip overturned horseshoe crabs on the NJ beaches of the Delaware Bay. You can join public walks that are held by walk leaders or sign up to be a volunteer
and conduct your own walk (until July 15th, 2023 or next year). I am a volunteer and walk leader
and it is one of my favorite things to do. Flipping horseshoe crabs is such a special event
because that means you’re saving those crabs so they can continue to spawn and produce eggs
for the shorebirds. With your help, you could help save hundreds of crabs just by flipping
them over! Of course I had to capture this special moment of me flipping a crab (picture below)!

On these walks, you experience much more than just crabs. You get to see other wildlife that
emerges during dusk or dawn. You can also go on the closed beaches to save the crabs that
can’t be rescued during the day. During my walk, I got to see thousands of horseshoe crab
eggs!

Every May the Delaware Bay is host to the largest concentration of spawning horseshoe crabs in the world. The shorebirds come to feast on these high-energy eggs, fueling up for their journey north to their breeding grounds. Since the 1990’s the number of horseshoe crabs has been in decline which has led to a decrease in the shorebird population.

There are many different organizations that have been researching these species and trying to protect and help increase the numbers of both the horseshoe crabs and shorebirds. One way to help protect the feeding shorebirds is to restrict access to beaches, May 7th-June 7th, where the birds concentrate in high numbers when feeding. Trained Shorebird Stewards are posted at these restricted access beaches in Cape May and Cumberland counties, to help educate the public and answer questions about the birds and horseshoe crabs. So far this season the horseshoe crabs have been spawning and the shorebirds are slowly trickling onto the beaches. Over the next two weeks the numbers of shorebirds arriving should be increasing. It’s a great time to stop by one of the bay beaches.

For the second year in a row there haven’t been eagles nesting on the Three Bridges platform in view of eagle cam. The pair used the platform when it was first installed in 2021 and viewers got to watch the two chicks grow up and fledge. In 2022 & 2023 the pair have nested in a tree nest instead of the platform. While it’s disappointing that the pair didn’t use the platform, there was still plenty of avian action at the tower this season. There were several immature eagles visiting the platform this season, perhaps in the next few years one of these eagles will pair up and use the platform.

Slideshow: Highlights from the 2023 Three Bridges Eagle cam season

The eagle cam will be turned off April 1st.

Thank you to all the viewers who watch and enjoy this eagle cam. During the 2023 season there were 22,981 views of the cam. Thank you to the the eagle project volunteers, especially Mary Ellen Hill, who grab screenshots from the cam. We also thank PSE&G for hosting and supporting the eagle camera.

See you next season!

I recently attended my first career fair at Stockton University. When asked if I would attend, I felt like I couldn’t say no, as I am currently seeking at least 5-6 student interns or seasonal field technicians to assist with several wildlife conservation projects. At first, I wasn’t sure what I could display to draw attention to our table and prospective summer jobs working with rare wildlife.. Then it hit me. I bring what I use when working with wildlife in the field!
