Shorebird stewards may not wear capes but they are superhero’s to the multitude of shorebirds stopping along the Delaware Bay in the spring.  During May, the beaches in New Jersey are an important stopover for these migratory birds who are mainly feeding on the horseshoe crab eggs, deposited during the annual horseshoe crab spawn.  The shorebirds, which include the red knot a NJ endangered species, have a short window to reach their ideal weight before leaving on the next half of their journey north to breed.  Eight beaches in Cape May County and two in Cumberland County have restricted access during the migration so that the shorebirds can feed undisturbed.

Since 2003 Conserve Wildlife Foundation has coordinated the Shorebird Stewards, who help protect the feeding shorebirds by educating the public.  This season thirty-one stewards were stationed at beaches between May 10th to May 26th.  While most stewards are from New Jersey, we have stewards from Pennsylvania, Delaware and Maryland. Some of the stewards volunteer for a day, while others work the entire season and many return year after year. No matter how often someone has been a steward, they have a made a difference and we have definitely seen a positive change in peoples attitudes over the years.  Visitors come from all over to view the shorebirds and horseshoe crabs and one of the main questions the stewards get asked is, “where are the shorebirds today”?

Some days the beach where the steward is assigned has only few shorebirds, while other days the beach is covered with the feeding birds.  While the majority of beach goers have a positive attitude about the beach restrictions, there will always be those that want to go on the beach.  While these situation aren’t always pleasant, the stewards are trained to handle them calmly and with education.

 

Thank you to 2025 shorebird superheroes!

This marked the second year that CWF worked in close partnership with New Jersey Fish and Wildlife and Edwin B. Forsythe National Wildlife Refuge (EBF) to monitor and manage birds on Horseshoe Island. The island, located just offshore on the southern edge of the Little Egg Inlet, has quickly become one of the most important sites for beach nesting birds in the state, as well as a critical resting and feeding site for migratory shorebirds.

Horseshoe Island hosted the state’s largest black skimmer (state endangered) colony this year with just over 1400 total adults or about 700 pairs. Although flooding and some avian predators impacted the overall nesting success at the island, at least 225 skimmer chicks “fledged” from the site. Horseshoe’s skimmer fledglings, along with those from nearby Holgate, a unit of EBF, and especially from Stone Harbor Point in Cape May County, made 2023 a moderately good productivity year for black skimmers in New Jersey.

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!

Conserve Wildlife Foundation’s research with scientist Dr. Larry Niles was highlighted in today’s New York Times feature detailing the 80 percent decline in red knots in New Jersey’s Delaware Bay this spring.

A sudden drop in the number of red knots visiting the beaches of Delaware Bay during migration this spring has renewed concern among scientists about the survival of the threatened shore bird’s Atlantic Coast population.

According to biologists, the number of knots that stayed to feed at the bay in May declined by about 80 percent from the same time last year. The Delaware Bay is one of the world’s most important sites for shorebird migration.

Direct Flight to the Arctic or Stopover?

A migratory stopover for arctic nesting shorebirds must provide each bird the energy necessary to get to the next stopover or to the ultimate destination, the wintering or breeding area. Delaware Bay stands out among these shorebird refueling stops because it delivers fuel in the form of horseshoe crab eggs giving birds options. Our telemetry has shown that Red knots, the species we best understand, may leave Delaware Bay and go directly to their Arctic breeding areas, or stopover on Hudson Bay. The choice of going straight to the breeding area or stop at another stopover may be critical to understanding the ecological dramas now underway on Delaware Bay.

reTURN the Favor Honored with 2019 New Jersey Governor’s Excellence Award

By: Meghan Kolk, Wildlife Biologist

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.

With the stopover period winding down, we can say the red knot and other shorebird species left the bay in better condition than the disastrous condition of last year. So what does it mean?

First, the last four years have been a sort of ecological roulette for the birds. Horseshoe crab numbers remained at only 1/3 the potential population possible on Delaware Bay leaving birds at the mercy of good conditions to get enough eggs. Last year, water temperatures stayed low during the mid-May depressing the spawn and the density of eggs. Although the average was 8000-eggs/square meter, there were less than 2000 eggs/ meters square in the month of May.
