In late 2024 we closed out our third year of comprehensive monitoring and management of nesting and migratory birds at Horseshoe Island. The recently formed island, situated just outside the southern edge of Little Egg Inlet, has quickly become one of the most important beach nesting bird sites in New Jersey. 

Each year has presented new challenges and changes on the island and in 2024 there were a number of “firsts” to report. Piping  plovers had previously utilized the island to rest and forage during both the migration and breeding seasons, this was the first year that they nested there. Adding any new nesting site for piping plovers in New Jersey is big news, adding three pairs was even more exciting. Although all three pairs hatched young, no chicks successfully fledged from the island, but we hope to build on that initial success next year.

Horseshoe Island is home to the northernmost royal tern colony in the hemisphere and the colony has grown in size each year. In 2024, CWF joined New Jersey Fish and Wildlife (NJFW) and The Wetlands Institute (TWI) to band royal tern chicks, the first time that royal terns have been banded in the state. With their newly minted blue field readable bands, we are now able to track movements and longevity of “our royals.”  Under NJFW’s direction, adult piping plovers were also banded at Horseshoe for the first time this year. Lastly, led by TWI, black skimmer chicks were once again banded on the island.

The island grew exponentially this year, it is now at least twice the size it was when monitoring began in 2021. The birds took advantage of the expanded habitat, upwards of 1400 state endangered black skimmers nested there in 2024, easily making it the largest skimmer colony in the state. And nearly 600 skimmer chicks fledged from the site, making it the most successful year to date for skimmers on Horseshoe Island. Large least and common tern colonies were also present. And American oystercatchers have increased from 6 to 16 breeding pairs since 2021; 2024 being the most productive year yet with 24 fledglings being recorded. Nearly every part of the island was in use, even more so if you factor in migratory and staging shorebirds that often crowd the tidal zones on the outer edges of the island and the interior lagoons for foraging.

Monitoring and management of the island is done as a partnership between CWF, NJFW, and Edwin B. Forsythe National Wildlife Refuge. For more information about the island, read the recently released 2024 report.

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!

Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, is having another record year for piping plovers. A total of 49 pairs have nested at the site this year, up from 46 pairs in 2021, which was also a record, by far, from the previous high for the site. Since Superstorm Sandy devastated much of the New Jersey coast in October 2012, the number of piping plovers nesting at Holgate has increased fourfold.

It’s officially chick season for the beach-nesting birds of New Jersey, and some of the first, fuzzy babies of the year were hatched at National Guard Training Center in Sea Girt. Piping plovers, Joey and Hamlet, laid their third nest together after first nesting at NGTC in 2019. The pair both had different partners that year, but got together in 2020 and fledged three chicks together for two years in a row. This year, the pair had the first confirmed nest in the state and diligently incubated their eggs during the entire month of May. The nest was anticipated to hatch over Memorial Day Weekend.

Just a couple days before the chicks made their appearance, tragedy struck. Hamlet was not seen for a couple days, and fear started growing that something had happened to her or she abandoned the nest, which would be very unlikely for such a devoted and successful veteran mother. When the chicks finally hatched from their eggs on May 29^th and only Joey was seen tending to them, some investigating was done into Hamlet’s disappearance. Her body was found at the edge of NGTC property, likely predated by an owl or other bird of prey, as evidenced by the condition of her body. As tragic and sad as her death was, it’s a wonder that her body was found at all. In many cases, there’s no closure for piping plover disappearances. Joey was left to raise his chicks as a single father, receiving praise and encouragement from everyone following his story. 

The chicks have reached the 10-day mark as of June 8^th, and appear healthy and strong. Only two have made it this far, but Joey is doing an excellent job on his own protecting them from threats and keeping them in line. We’re keeping our fingers crossed that both chicks make it to fledging, and Joey can keep up his excellent fatherhood record. It’s unknown if Joey will seek a new mate next year or retire from parenthood, but for now, we are saddened by the end of the era of Joey and Hamlet. 

Monitoring of beach-nesting birds takes time and commitment from our team of biologists and seasonal technicians. The largest piping plover breeding population in New Jersey resides at our Holgate site, where pairs, nests and hatched chicks are observed and tracked nearly every day during the nesting season. Nests north of that site are sparser and face many threats from human disturbance and high predator presence. While the coastal piping plover population is still struggling, CWF continues to fight to protect our state’s rare species and educate the public about the importance of respecting wildlife.

Since 2003 Conserve Wildlife Foundation has been coordinating the Delaware Bay Shorebird Stewards. Shorebird Stewards are posted at the beaches with restricted access during the shorebird season. This is done so that the shorebirds can feed undisturbed on horseshoe crab eggs. The beach restrictions are from May 7th to June 7th. The Delaware Bay is an important stopover for these birds on their way north to their breeding grounds. Stewards educate the public about the need for the beach restrictions. Once most people learn about the connection between the horseshoe crabs and shorebirds, they are more than happy to accept the restrictions. This season there were thirty-one stewards on 10 beaches in Cape May and Cumberland Counties. They are dedicated and on the beaches despite the weather, bugs and sometimes lack of shorebirds. Stewards are on beaches through Monday, so stop by and say “hello”.

Thank you Shorebird Stewards

For the past eight years, CWF has been contracted by the U.S. Fish and Wildlife Service through a cooperative agreement to provide monitoring and management of beach nesting birds at the Edwin B. Forsythe National Wildlife Refuge. The Refuge nesting sites – both the Holgate and Little Beach Island Units – provide some of the only habitat in the state closed to the public and free of human disturbance and detrimental beach management practices. The habitat at the sites is especially suitable for the state endangered piping plover as a result of optimal nesting conditions created by Superstorm Sandy and largely sustained since then through winter storms. As of the 2021 season, the Refuge sites had the highest concentration of piping plovers in the state, with Holgate having by far the most pairs (46). Furthermore, on average in recent years, Holgate has produced a higher fledgling rate than many sites in the state.

Our infamous Piping Plover pair, Joey and Hamlet, officially have a nest!

Joey (the male), and Hamlet (the female) were seen exhibiting breeding behavior for weeks since arriving back to their nesting grounds. The pair had been favoring a spot recently improved with habitat enhancements that included removing dense American beach grass and adding shell cover.

Something unusual and exciting has happened just off the coast of New Jersey; a new island that has become a haven for birds has formed. Located on the southern edge of the Little Egg Inlet, the island is about 1000 feet offshore of Little Beach Island, a Unit of the Edwin B. Forsythe National Wildlife Refuge (Refuge). Of course, it didn’t form overnight, an emergent shoal has been noted in that location since about 2018, and it has slowly been growing, likely as a result of the longshore drift of sand from Long Beach Island. The island, dubbed Horseshoe Island because of its distinctive shape, provides incredibly valuable habitat for nesting and migratory birds, including many at-risk species.
