Just a few hours after landing on the island of Abaco in the Bahamas in early February, I had my scope focused on several dozen piping plovers scurrying across an expansive sand flat. This was good news; the foraging flat still supported a healthy number of wintering plovers. The last time I had been at this site was almost exactly three years ago. A lot has happened since then.

On September 1, 2019, a major Category 5 storm, Hurricane Dorian, struck and lingered over the island of Abaco, and then Grand Bahama, bringing with it sustained winds of 185 MPH and gusts of 220 MPH, the strongest storm on record to hit the Bahamas. As expected from a storm of this intensity, lives were lost and devastating damage occurred to buildings and infrastructure. The natural environment took a beating too. As just one example, the pine forests, typical of these two Bahamian islands, that were in the direct path of the storm were nearly entirely destroyed – even today, 2 ½ years later, the sight of a “ghost forest” as far as the eye can see is a shocking sight.

Habitat Enhancements for Rare Species at the Sea Girt National Guard Training Center

by Meaghan Lyon, Wildlife Biologist

Although the Sea Girt National Guard Training Center (NGTC) has just a small section of beach to manage, their efforts there with threatened and endangered species has been big. Conserve Wildlife Foundation of New Jersey has been a partner in these efforts, monitoring the piping plovers that nest on this beach during the breeding season and assisting in the planning of habitat enhancements. The protection area at the NGTC has been the nesting site of a piping plover pair for the past three breeding seasons and it is likely they will return again this spring, all while supporting the military and recreational missions of the New Jersey Army National Guard.

CWF Assists the State with Wintering American Oystercatcher Survey

by Todd Pover, Senior Wildlife Biologist

American oystercatcher winter flock.

Most people are surprised to hear that American oystercatchers are present in New Jersey in the winter. They usually associate the charismatic shorebird as a breeding species here. Our state’s wintering oystercatchers, a combination of breeders from further north and our own, are at the northern extent of the Atlantic coast wintering range.

With 2021 coming to an end, we thought it would be fun to look back at this year’s beach nesting bird season in New Jersey, focusing on some of the surprises.

At the top of the list is the huge jump in our piping plover breeding population, up to 137 pairs from just 103 in 2020, an unprecedented 33% increase in one year and the third highest on record for the state since federal listing. This was a much-needed bump, as productivity has been high over the past few years, but we weren’t seeing any sustained growth in the population as a result as would be typical. So, when the final pair number was tallied this year, we were both relieved and surprised at how big it was! The challenge now will be to maintain that higher level or increase it even more, as it has fluctuated up and down quite a bit in recent years.

New Jersey Piping Plover Breeding Population Rises Sharply in 2021

By Todd Pover, Senior Wildlife Biologist

The 2021 New Jersey piping plover breeding season was a classic “good news, bad news” result. According to the annual report released by the state’s Endangered and Nongame Species Program earlier this month, the breeding population increased to 137 pairs in 2021, third highest since federal listing in 1986. That is an unprecedented 33% rise over the previous year and just short of the record high of 144 pairs in 2003. On the downside, the number of chicks fledged statewide was just 0.85 chicks per pair, the lowest since 2013 and about half of the 1.50 federal recovery goal. The low productivity was largely the result of a severe Memorial Day weekend nor’easter and persistent predator activity throughout the season.

Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, hosted 46 pairs, the most in the state. This site, which is monitored and managed by CWF through a cooperative agreement with the Refuge, has seen an astounding increase in piping plover pairs in recent years, up about 2.5 times from the 18 pairs it had in 2018. CWF also monitors Little Beach, the adjacent Refuge-owned site, where another 13 pairs nested in 2021. Combined the two sites had 59 nesting pairs, a new record, by far, for the Refuge. Unfortunately, like the statewide results, productivity was very low this year at both Refuge sites, combined only 0.80 chicks fledged per pair, about half the rate just a year ago. The Memorial Day weekend nor’easter flooded those sites, wiping out most nests, and although most of the pairs nested again afterwards, many of those renests (or hatched chicks) were lost to predators, especially coyotes at Holgate.

CWF also oversaw piping plover breeding at the National Guard Training Center, which had just one pair in 2021, but that nest successfully hatched and fledged three chicks, helping boost the state average. Overall, CWF was responsible for monitoring 44% of the statewide population, giving it a significant role in helping guide conservation of this highly vulnerable state endangered (and federally threatened) species.

Although CWF does not conduct the daily on-the-ground monitoring and management of piping plovers at the Barnegat Inlet nesting site, it was a co-leader of the habitat restoration that was completed there two winters ago, and as such has had a big role in the nesting outcomes at the site. The number of pairs using the site has noticeably grown, up to five pairs in 2021 from just one pair when the project began. Productivity has also been consistently high at the restoration site and 2021 was no different with the pairs exceeding the federal recovery goal and statewide average with 1.6 chicks fledged per pair this year.

With the breeding results for 2021 now “in the books”, we are already looking forward to next year. The biggest question will be whether the state can sustain the progress towards recovery it made this year, especially given the big drop in productivity, which typically drives population. But for now, all we can do is wait until next spring to learn the answer to that question.

The Mysterious Oystercatchers of the Delaware Bay: Results of the 2021 Bay-Wide Survey

By: Meghan Kolk, CWF Wildlife Biologist

The Delaware Bay is well known for the spectacular phenomenon of spawning horseshoe crabs and migrating red knots every May, but in recent years the American oystercatchers (Haematopus palliatus) have also discovered the allure of the Bayshore and made it their home.  American oystercatchers, a State Species of Special Concern, have been monitored and managed by CWF and the NJDFW’s Endangered and Non-game Species Program along the Atlantic coast beaches for nearly two decades, resulting in a steady population increase.  However, the population that breeds along the Bayshore, first documented in 2016, has not received the same attention and had never been fully surveyed until this year. 

CWF’s interest in this newly discovered population led to a small pilot study of a few known breeding pairs in 2018.  Then this past May, we launched a bay-wide survey of the sandy beaches of the New Jersey side of the Bay from Cape May Point up to Seabreeze, the northernmost beach in Cumberland County.  The purpose of the bay-wide survey is to determine a baseline of the number and distribution of breeding pairs along the Bayshore.  The data gathered from this survey will add to the Statewide population estimate and help determine the amount of time and funding needed to fully monitor and manage the Bay’s population.  More monitoring will be necessary to assess risk factors and reproductive success.  Reproductive success can then be maximized by managing for risk factors such human disturbance, predation and tidal flooding.

This survey was made possible due to the efforts of dedicated volunteers and could not have been completed without their help.  Unlike the Atlantic coast, the Bayshore beaches are often difficult to access, and many can only be reached by boat, making this survey more challenging.  In fact, two sites that we planned to survey proved to be too difficult to reach and were skipped for this year.  Each of the 33 remaining sites were surveyed just once within a specific timeframe, giving only a snapshot of the breeding season.  We hope to be able to collect much more information in the future when more funding for this project is available.  Based on the survey that was conducted, 13 pairs were documented at 8 different sites and 8 nests were documented at 5 different sites.

In addition to the formal survey, I was able to collect some observations as I spent every day in May on the Bay working with red knots.  I took notice of the prey items that the oystercatchers were choosing.  I often observed them feasting on oysters, which were plucked off exposed rubble at low tide.  They also spent time at the man-made oyster reefs that were constructed at several beaches to act as breakwaters to slow the erosion of beaches.  They also favored ribbed mussel beds, which become exposed as the tide recedes.  The most interesting foraging behavior I witnessed was an oystercatcher plucking a fresh slipper shell off a horseshoe crab as it came to shore to spawn.  It seems the Bay offers a variety of good food sources for a bird that mainly preys on bivalve mollusks. 

I also noticed that flocks of up to 11 oystercatchers were traveling together up and down the Bayshore.  This is a peculiar behavior since oystercatchers are highly territorial during the breeding season and are typically only seen in flocks once the breeding season is over.  Could it be that the Bayshore is a popular spot for non-breeding young adults to hang out? 

So much more research is needed to answer the many questions we have about the mysterious Bayshore oystercatchers. 

Barnegat Light Habitat Restoration: Measuring Success by More Than Just the Numbers

By Todd Pover, Senior Wildlife Biologist

The success of a habitat restoration project is typically measured in numbers, number of acres restored, the abundance of target species, breeding success of the wildlife using it, that sort of thing. And we certainly have good numbers for the Barnegat Light Habitat Restoration Project… 40 acres restored, including two foraging pond, five pairs of piping plovers using the site this year, a substantial increase from one pair just two years ago, and breeding success above the federal recovery goal and well above the state average for two years running since the project was fully completed.

But there’s more to the success than numbers, it can also be told through names. So first a disclaimer; we name our banded piping plovers in New Jersey. This practice is sometimes frowned upon by other researchers who fear anthropomorphism undermines their scientific credibility or leads to misunderstanding about biological processes.  Point taken, but in the case of piping plovers, we believe naming can potentially lead to better engagement in their conservation through dynamic outreach, much the way Monty and Rose, Chicago’s famous plovers have garnered huge public support. Also, in New Jersey our banded plovers typically have four bands, so it is much easier for our monitoring staff to identify and communicate about a bird named “Major Tom” than orange over light blue (left), orange over black (right). Finally, some people are just plain curmudgeons about this issue, but endangered species recovery work is hard, so having a little fun with it isn’t such an awful thing! So, let’s get to the names and the “stories” they tell.

Meeting Monty and Rose, Piping Plover Ambassadors

By Todd Pover, Senior Wildlife Biologist

Monty and Rose were hardly strangers when I finally met them “in-person”. I had been admiring Chicago’s famous pair of piping plovers for nearly two years. I had read the adoring newspaper headlines about them and followed them closely on social media. I had seen, even hosted a screening for the short film made about their story. I proudly wore a hat emblazoned with their colorful logo.

From a strictly biological perspective, Monty and Rose aren’t much different than any other piping plovers; they have the same distinct markings, exhibit the same behaviors, and face the same threats that have landed plovers on the endangered species list. But there is nothing ordinary about this pair when it comes to the attention afforded them and the excitement they’ve created.

So early this summer I found myself on a plane headed to Chicago to experience the Monty and Rose phenomenon firsthand. Along for the pilgrimage were Kashi Davis and Emily Heiser, who head up New Jersey’s beach nesting bird program, and with whom I’ve share nearly my entire career. With nearly 60 years of “plovering” between us, you wouldn’t think we’d have much to learn from yet another pair of plovers. To be honest, the trip was as much about being inspired by Monty and Rose and the people involved in their story, as it was about anything else. But on the practical side, I was especially interested in how they managed to pull off a dawn to dusk volunteer monitoring program from incubation to hatch to fledge. And I really wanted to know how they generated all that excitement.

The novelty factor accounts for some of the appeal, the first plovers nesting in Chicago in many decades. But interest in Monty and Rose has continued to rage on several year running now, and a second film is scheduled for release in September, so it isn’t just that. Improbability also plays a part, a small pair of shorebirds and their even tinier chicks nesting on a busy city beach in the shadow of skyscrapers. The naming of the birds, a reference to Montrose Beach, where they nest, also seems to play an important role in the connection people feel for them. There is a great sense of pride – they are their plovers. And with just one pair at this site (and in the entire region), all the attention is funneled to them.

You feel the excitement the moment you walk on “their” beach. People constantly pop by to ask how Monty and Rose are doing. The volunteer monitors happily trade personal stories about them or offer a look in their scope to get a closer peak. Strangers wander over to ask what everyone is looking at. We met Bob Dolgan, the creator of the Monty and Rose film (and its upcoming sequel), and Tamia Itani, the pair’s “plover mother”, organizer of the volunteer effort, and now author of a Monty and Rose children’s book. Both had their own take on why the Monty and Rose story has gone viral, although I’m not sure I’ll ever know exactly what that “secret sauce” is. No matter, I left Chicago completely inspired by Monty and Rose and their protectors, recharged and ready to carry on with my own plover projects back home.

A few days after returning from Chicago, I took a day trip up to Gloucester, Massachusetts to meet some members of another piping plover volunteer group. Like the Monty and Rose crew, they annually help shepherd one pair of plovers (actually, they have two pairs this year) through the perils of nesting on a city beach, although Good Harbor Beach is decidedly quieter than Montrose Beach in Chicago, at least on the mid-week morning I visited. This group also manages to staff the beach with monitors from dawn to dusk on most days and has its own Facebook page that it maintains to educate the public and generate enthusiasm for their community’s plovers. They have been doing this longer than the Monty and Rose effort, but quietly out of the spotlight. They proudly wear their Piping Plover Ambassador badges.

Seeing those badges made me realize that although the Monty and Rose story has been invaluable for creating interest in plover conservation – piping plovers are definitely having a “moment” thanks to their story – it’s the hundreds of monitors who are the real piping plover ambassadors. I started my own “plover career” 28 years ago as a volunteer. I was immediately and inexplicably smitten by piping plovers, although I didn’t realize it would completely change my life. I’m just as captivated by piping plovers today and I remain equally inspired by my fellow protectors, paid and volunteer, who steadfastly fight to help maintain a place for piping plovers in our world. And provide them a voice.

Delaware Bay Shorebird Stewards: Protecting Shorebirds

By: Larissa Smith, CWF Wildlife Biologist

Shorebird Steward Tony Natale

There are many aspects to the Delaware Bay Shorebird Project. During the month of May researchers survey, re-sight and band shorebirds as well as conduct horseshoe crab egg counts. Nine beaches in Cape May and Cumberland Counties have restricted access during May, which allows the shorebirds to feed on the horseshoe crab eggs.

Shorebird Steward Bill Reinert@ Dom Manalo

Shorebird stewards are out on the beaches in all types of weather and insect seasons making sure that the restricted areas are respected. They do this through education and explaining to beach goers the importance of allowing shorebirds to have these undisturbed areas to feed. Stewards really make a big difference in shorebird protection on the bay and we thank them for all of their efforts this shorebird season. This season there were plenty of horseshoe crabs spawning with eggs in abundance, but unfortunately the shorebird numbers were down this season. For more details on the 2021 Shorebird season can be found in the article ,Red knot numbers plummet, pushing shorebird closer to extinction.
