While the July 4th holiday weekend is the celebratory peak of the summer season for beachgoers, it is not a joyous time for beachnester staff or beach nesting birds. The holiday brings an extra crush of people out on the beaches at the most critical time for our endangered nesting shorebirds. Nearly all the species – piping plover, least tern, black skimmer, and American oystercatcher – are at the peak of their breeding seasons in late June/early July so the holiday is sometimes a “make it or break it” day or in the case this year a long weekend.
So our beachnester staff went into overdrive this weekend, working extra hours to guard and monitor nesting sites, both day AND night. Fireworks, the symbol and heart of any July 4 celebration, are especially problematic. The disturbance from the fireworks themselves can be an issue, but the extra large crowds (and typically extra boisterous behavior) on the beaches at night can be a deadly combination for the beach nesting birds. Personal fireworks in proximity to nesting colonies also have to be “policed” by our staff and volunteers.
With this year’s holiday now just passed, it looks like our efforts largely paid off. There were areas where protective fence was vandalized and had to be restored, and some minor bird losses were documented this weekend, but it was fortunately minimized this year. With that in mind, we are sending an extra special thanks out today to the dedicated beachnester staff members and volunteers, not just in New Jersey but across the entire breeding range, for their hard work this weekend and throughout the season.
The bird’s still have several weeks to go before we’ll know if the season was a success overall (stay tuned for that news), but “holding down the fort” on July 4 is one more challenge that is now in the books for this year.

Piping plovers tend to garner most of our attention on the beach nesting bird project because they are so critically endangered. American oystercatchers and black skimmers are visually striking and very charismatic, so they are popular with the public, as well. That sometimes leaves the least tern as the “forgotten stepchild” of our beachnesters.
Their protective behavior of dive-bombing and even pooping on beachgoers who get too close to their nests or young doesn’t help their reputation. Yet, they are a fascinating species to watch and their chicks rank high on the cute scale.
Because they are a colonial species, and the colonies often take up large areas of the beach, they are a special challenge to manage and protect. But they do need protection – they are listed as endangered in New Jersey. Over the past decade, their population has remained low but stable. On one hand that is good, it means they aren’t declining further, but it also means they aren’t recovering either.
This week, we completed the latest of our bi-monthly surveys with a total of about 1200 individuals counted. This is below our peak a little earlier in the month, but in line with our typical statewide population. To date, we have recorded 24 active colonies along the coast from Sandy Hook to Cape May this year. That is within our average annual range of 20-25, although several of those colonies have already failed due to intense predator pressure.
It is too early to say whether this will be a good or bad year for least terns. We are in the peak period for chicks, so the next two weeks or so will determine if we successfully produce enough young to the fledgling stage. In the meantime, now is the time to get out to see these cuties, but remember to view them from a safe distance and share the shore with all our beach nesting birds.

Amazing transformation of a piping plover from tiny chick to fledgling in just 25 days. Both photos by Northside Jim.
The highlight of this past week was our first piping plover fledglings of the season. This means the first group of chicks has reached the stage where they can fly, which is our metric for success. Hatching the chicks is always great, but our goal is population recovery and the primary way we can increase our low population in New Jersey is to produce more fledglings to come back in future years to breed here.
The doubly exciting news is ALL four of the chicks that hatched at Barnegat Light reached the flying stage. This is notable because typically, on average, we only fledge about one chick per pair in New Jersey. This is not enough to grow or sustain our long-term population. Population modeling tells us we need to fledge about 1.5 chicks per pair range-wide to grow the population and about 1.25 chicks per pair to sustain it.
Of course, not all our piping plover pairs will fledge four chicks, in fact, some may not fledge any. So the Barnegat Light news was a good way to kick off our fledgling season and hopefully it is a sign of above average productivity this year.

The beach nesting bird field staff is firing on all cylinders now, frantically trying to keep up with nesting activity. In some regions of the New Jersey coast, piping plovers and American oystercatchers are still laying eggs, while at other sites there are chicks on the beach, even one site (Barnegat Light) where the chicks are already approaching their “fledgling” stage when they will be able to fly.

Most of the least tern and black skimmer colonies are now established, with least terns starting to hatch chicks and black skimmers just laying eggs. Counting the colonies is one of the most challenging parts of the job, imagine trying to count 1,000-1,500 birds at a time in some instances!
After helping with the winter segment of the International Piping Plover Census in the Bahamas, CWF switched gears this week to help conduct the breeding portion in New Jersey.
All the normal beachnester tasks are keeping us busy, but the main focus this past week was the annual piping plover “window” census, where field biologists all along the Atlantic coast count the number of birds present between June 1-9, so we can get a range-wide breeding population estimate. As for New Jersey, it looks like our population will go up, at least slightly, for the second year in a row. Although this is still a very preliminary estimate, it looks like we have weathered the statewide low in breeding pairs we recorded in 2014, thanks to good productivity the past two years.
Of special note is a spike in Monmouth County (outside Sandy Hook), where we have gone from 2 pairs the past several years to 12 pairs this year. Although a smaller bump, we also went from 1 pair to 4 pairs within Barnegat Inlet, an area we have long hoped for more pairs. It takes a tremendous effort to realize even small gains in our piping plover recovery effort, so we are especially excited about this news!

New, weekly updates from New Jersey’s beach nesting bird project team

American oystercatcher Chick
It has been a busy week on the beach nesting bird project! We had our first least tern nests of the season, as the brief spell of warmer weather (finally) made for a burst of breeding activity. The first American oystercatcher nests hatched, so we have chicks on the beach now, as well.
Least Tern Nest
And there was a big spike in new piping plover nests all along the coast, so we were busy erecting “predator exclosures” to protect the eggs from predators, such as crows, cats, gulls, and foxes. While they are not effective or viable to use on every nest, these wire cage structures are one of our best management techniques to increase hatch success by deterring predators.
Piping Plover Exclosure
This week we will be even busier, as we make a mad scramble to protect the nests and colonies before the crowds of beachgoers arrive for the Memorial Day weekend!
CWF is Celebrating International Migratory Bird Day all Week Long
by Lindsay McNamara, Communications Manager
CWF’s blog on the piping plover is the second in a series of five to be posted this week in celebration of International Migratory Bird Day (IMBD). IMBD 2016 is Saturday, May 14. This #birdyear, we are honoring 100 years of the Migratory Bird Treaty. This landmark treat has protected nearly all migratory bird species in the U.S. and Canada for the last century.

The piping plover – a small sand-colored shorebird that nests in New Jersey as part of its Atlantic Coast range from North Carolina up to Eastern Canada –weighs only one to two ounces and is about six to six and a half inches long. These tiny shorebirds migrate all the way to their wintering grounds along the coast of eastern Mexico and on Caribbean islands from Barbados to Cuba and the Bahamas.
Migrants can be seen in New Jersey from early March to late April and again from mid-July to the end of October. Females are the first to leave the breeding grounds, followed by males, then juveniles. Breeding plover “hot spots” in each coastal county of New Jersey are Gateway National Recreation Area – Sandy Hook Unit, Barnegat Light, North Brigantine Natural Area and Stone Harbor Point.
We see a number of migratory piping plovers in New Jersey because the Garden State is roughly in the middle of their breeding range. Todd Pover, CWF’s beach nesting bird project manager, reasons that we have a high number of Eastern/Atlantic Coast Canadian breeders that stop in New Jersey — based on band resights — albeit usually for just a day on their way north to breeding grounds. Therefore, New Jersey may play an important role in the piping plover life cycle not just for breeding, but for migration as well, which emphasizes the importance of protecting shorebirds in all phase of their lives or “full life-cycle conservation”.
Piping plovers face a number of threats, including intensive human recreational activity on beaches where they nest, high density of predators, and a shortage of highly suitable habitat due to development of barrier islands and extreme habitat alteration. Sea level rise and increased storm activity related to climate change will also likely lead to more flooding of nests.
Federally listed as a threatened species in 1986, piping plovers have since recovered in some areas of the breeding range. Yet piping plovers continue to struggle in New Jersey, where they are listed by the state as endangered. For more information about piping plover nesting results in New Jersey, please read Conserve Wildlife Foundation’s 2015 report.

CWF, in close coordination with NJDFW’s Endangered and Nongame Species Program, oversees piping plover conservation throughout New Jersey. Staff and volunteers help erect fence and signage to protect nesting sites, monitor breeding pairs frequently throughout the entire nesting season from March to August, and work with public and municipalities to educate them on ways to minimize impacts. Although conservation efforts on the breeding ground remain the primary focus, in recent years, CWF has also begun to work with partners all along the flyway, in particular on the winter grounds in the Bahamas, to better protect the at-risk species during its entire life-cycle.
We are working hard to link students across the piping plover’s flyway through our Shorebird Sister School Network, where we pair up schools in New Jersey and the Bahamas, one of the most important wintering areas for Atlantic Coast piping plovers. Now, we are hopefully recruiting some Canadian students as well.
Conserve Wildlife Foundation will continue to find innovative ways to save the small migratory shorebird. In 2015, 108 pairs of piping plovers nested in New Jersey, a 17% increase from 2014. What will 2016 bring? Follow us on social media to learn more about the tireless efforts of a team of passionate, dedicated biologists working to save the iconic coastal species.
CWF Releases its First Annual Report Ever Using a Story Map Format: “2014 Annual Report“
By David Wheeler, Executive Director
Technology has proven to be vital to Conserve Wildlife Foundation’s work protecting rare wildlife species over the years. Our biologists depend greatly on modern technologies to band, track, and share online the journeys of wildlife. Our webcams broadcast the most intimate behaviors of nesting birds and bats across the web. And we seek out ever-evolving communications technologies to spread the word about the inspiring stories of wildlife, from social media and infographs to e-books and Story Maps. These technologies offer newfound abilities to share complex data on multiple levels, while still incorporating the awe-inspiring photography and videos that bring wildlife’s stories to life.
Conserve Wildlife Foundation of New Jersey is excited to offer our 2014 Annual Report in a unique format that utilizes one of those technologies – Story Maps. In the past year, we have explored the wonders of American oystercatchers with our first Story Map – and now the annual report allows all of our projects to be highlighted in this interactive format.

CWFNJ AND MONMOUTH UNIVERSITY PARTNER IN THE BAHAMAS

We totally shifted gears for the second half of our week here on Eleuthera, The Bahamas. Piping Plover surveys took a back seat as we focused on working with 20 students from Monmouth University (MU), who were taking part of in a two-week Tropical Island Ecology course during their winter break.
We settled into the Cape Eleuthera Institute, who hosted the students at their world class facilities for an intense (but fun) regimen of hands-on science research, typically marine based, but a Piping Plover unit was added for the MU students. It was particularly exciting to work with the MU students here in the Bahamas because back in New Jersey we have partnered with MU for over ten years on a beach nesting bird internship program during the summer months.
First up was an evening primer for the students on Piping Plovers, including a brief summary of our efforts in NJ on the breeding grounds and recent work by CWFNJ and others on the wintering grounds in the Bahamas. The next morning we were up early to kick off our trial research project; benthic macro-invertebrate sampling at Piping Plover wintering sites in the Bahamas to try to develop an inventory of their potential prey items, and eventually determine what constitutes a highly suitable foraging site. This was spurred, in part, by field observations of tidal flats that appear to be highly suitable, but have no piping plovers present, whereas similar adjacent flats are covered with shorebirds. Perhaps not all flats are created equal and prey availability is the key.
Students collecting and processing the sediment samples as part of the research to assess foraging quality.
For our field work with the students we chose two sites in Eleuthera where Piping Plovers have been observed; Savannah Sound, a classic low-tide flat in a sheltered area, and Winding Bay, an oceanfront, high-energy beach. The students extracted core sediment samples (20 cm deep) at each site along prescribed transects (10 samples per transect) for two consecutive days. Then it was back to the lab to sift the sand, sort the samples, and identify any invertebrates found. As part of the analysis, the students compared the species abundance and diversity between the two different sites, as well as between different transects within a site.
The results are yet to come and this was just a preliminary test of the methods and logistics involved. We were learning along with the students and while we were happy with the overall outcome, many questions were raised that will have to be addressed if we decide to develop a larger more robust study moving forward. In the meantime, the students got to learn a bit about Piping Plovers in the context of a research project, and inaugurate what we hope is another long-term partnership in the Bahamas.

A special thanks to the staff at Cape Eleuthera Institute for their hospitality and for letting us be part of their innovative learning experience. Thanks to John Tiedemann and Pedram Daneshgar at Monmouth University for setting the wheels in motion and now helping us implement this partnership. And finally, “shout-out” to Taylor Rodenberg for stepping up to assist us with the field work – Taylor was one of our MU interns in New Jersey last summer and happened to be one of the students visiting the Bahamas this winter, so she is part of a small group of lucky people to see (and work with) Piping Plovers on both their breeding and wintering grounds!
CWF RESEARCHERS EXPAND SURVEYS TO ANOTHER ISLAND IN THE BAHAMAS
By Todd Pover, Beach Nesting Bird Project Manager and Stephanie Egger, Wildlife Biologist
Todd Pover, CWF Biologist, surveying for Piping Plovers using the final minutes of daylight.
Our experience so far this week in Eleuthera is a reminder why we do so much pre-trip “recon” for our Bahamas Piping Plover Project. Prior to the trip, we poured over Google Earth maps to try to identify the most suitable habitat for plovers. We read (and reread) the report from the 2011 International Piping Plover Census, the last time any significant surveys were conducted here. Finally, we “huddled” with our partners from Monmouth University so they could help us with logistics, as they have a history of marine-based research here.
Without this preparation we would have been ill prepared, of course, but we still faced many challenges right out of the gate. First and foremost, Eleuthera is more than 100 miles long, with two coasts, so covering even a small portion of the island is difficult in a short period of time. Once we decided which sites were the top priority, we quickly found out that reaching those locations is difficult. There are few official signs to the shoreline on the Atlantic side along the one main “highway”, and many of the “roads” are difficult to traverse, even with a 4WD. A number of turnoffs ended as dead ends or too overgrown to continue.
Piping Plover “Gry E4” was banded as a chick at White Point Beach, southern Nova Scotia in June 2014. Resighted on Spanish Wells and the first time reported after the breeding season.
It also quickly became apparent that Eleuthera’s rocky coast, especially along the western side is not nearly as suitable for piping plovers as we had experienced on earlier trips to Abaco and Grand Bahama. And some of the beaches on the Atlantic side were too narrow to likely support piping plovers. Not surprisingly, the initial day of surveys ended with a lot of lessons learned, but NO piping plovers.
Day Two we took an entirely different tack. We left our vehicle on the mainland and headed out on small ferries to two islands off the northern coast of Eleuthera; Spanish Wells, a residential community with a commercial lobster port and Harbor Island, a resort town known for its famous Pink Sands Beach. Our luck turned around, as we observed 20 piping plovers (with relative ease) including four that were marked with engraved flags that denoted they were Canadian breeders. This was one of the highlights of all our Bahamas trips to date.
We were also able to track the movement of 18 plovers from a high tide roost on the ocean side beach to a low tide flat on the other side of the island as the sun set. From what we learned on Abaco on previous trips to the Bahamas, this type of information is some of the most critical we can collect to help inform future surveys. We definitely earned our celebratory Kaliks that evening!
On the road to nowhere – locating piping plover sites on Eleuthera was a logistic challenge at times.
Our goals for the surveys this week are modest. We are trying to confirm some of the site information our colleagues Pat and Doris Leary gathered during the 2011 International Census, as well as add some additional sites to the survey inventory. We also are trying to visit high value sites, such as Savannah Sound, to determine which tide or portion of the tide is most productive for the surveys. With this information in hand, we hope to do our small part to help make the 2016 International Census next winter the most productive and accurate to date.
We talk quite a bit about “site fidelity” in connection with our beach nesting bird project. And for good reason, whether it be on the breeding or wintering grounds, these birds, like most wildlife, are strongly connected to specific places and types of habitats. Not just in the general sense; many piping plovers return to the same precise site year after year.
Aerial view of one of several hundred Bahamas islands and cays, with tidal flats, highly suitable piping plover habitat, visible stretching around the island.
We were reminded of this the last several days as we made our way around Abaco, The Bahamas, in search of wintering piping plovers. Having made a number of trips to Abaco since 2011, we have started to narrow down where it is likely we will be able to find them: the Green Turtle Cay Gillam Bay flat at low tide or the adjacent upper beach hummocks at high tide, Casuarina Point to forage at low tide, a number of the main island’s southern oceanfront beaches for roosting, to name a few. We are still finding new sites, not previously surveyed or documented, but we now have a much better idea of what to look for and on what tide or wind condition.
The catch is, this only works if the habitat remains intact and suitable. Back in New Jersey, we know this well, as many of the formerly suitable sites for beach nesting birds are lost forever to development or are highly disturbed by recreational activities so the likelihood of reproductive success is low even if they do choose to nest at those locations. Sadly, our breeding pairs of piping plover are relegated to a limited number of suitable sites, which is not a good recipe for recovery of this endangered shorebird.
With its hundreds of islands and cays, many undeveloped or lightly settled, we may be inclined to think this is less of an issue on the wintering grounds in the Bahamas. And relatively speaking, this might be true to some extent, but it would be unwise to believe this will always be the case. Economic forces are a driving factor there, as in anywhere in the world, so the lure of development and commercial use of resources is strong in the Bahamas as well.

Fortunately, there is also a strong incentive to protect shorebirds in the Bahamas. The tidal flats and shallow water habitats that shorebirds use are also important for bonefish, conch, and other fisheries that are important to the local economy and provide jobs. Furthermore, birding and wildlife-based activities are increasing an important part of the tourist sector. However, In order to sustain those activities and opportunities, ecosystems must remain intact and pristine.
A number of organizations, local and from abroad, are diligently working to designate more protected areas in the Bahamas. One of the top priorities now, an effort being led by the Bahamas National Trust and National Audubon Society, is to protect the vast flats area in the Joulter Cays, Andros, which are especially important for shorebirds such as the piping plover. On Abaco, where we have been focusing our piping plover work, Friends of the Environment is strongly advocating for protection of East Abaco Creeks, Cross Harbour, and more recently The Marls.
During a survey this past week on Man-O-War, one of Abaco’s offshore cays, we were able to locate a banded piping plover that had originally been marked on its breeding grounds in Canada. In discussing the bird with a local resident who had first spotted it, she was surprised that the bird was remaining in the same spot ever since she saw it two months ago. This was site fidelity illustrated in its truest sense, and in the same vein, the researchers in Canada are already anticipating it will return to the same site to nest next spring. From what we know about piping plovers that is highly likely…as long as we remain committed to protecting the habitat they use.
