Up until now the focus of our weekly reports has been on breeding activities – for good reason as that is the main purpose of our beachnesting bird management and recovery program here in New Jersey. However, the past two weeks have been a good reminder that piping plover migration is already well under way.
The idea of “fall” migration is a bit of a misnomer for piping plovers and other shorebirds since they begin moving south for the “winter” as soon as nesting is complete. For piping plovers that can be in early July. In fact, last week we had our first report of piping plovers already back on their wintering grounds in the Bahamas. And yesterday we received word of 164 piping plovers in Ocracoke, North Carolina, many of them individuals that had bred in states further north. We know that from the bands and flags placed on the birds as part of various research projects.
Meanwhile, back in New Jersey we resighted our first Canadian piping plover on July 12. Then last week we had another very exciting visitor from Canada – a flagged bird with the alpha/numeric code of E4. CWF’s very own Todd Pover had spotted this bird on its wintering ground in January 2014 in Spanish Wells, Eleuthera, the Bahamas. In the spring of 2014 Todd traveled up to this bird’s breeding location at White Point Resort in Nova Scotia, Canada, where he was able to spy the bird with its mate as they started to set up their nest. Having it now show up during migration in New Jersey completed the circle.
Although Todd didn’t see it himself in New Jersey this time, there is some pretty amazing “dots being connected” with this individual bird. One of the important issues brought up by the resightings of E4 is just how connected the sites are all along the flyway. It is important that we focus on breeding success here in New Jersey, but we also play an important role in protecting shorebirds during different phases of their lives as well. Long term survival and recovery of piping plovers depends on full life cycle conservation, not just during the breeding season. And with many shorebirds moving thousands of miles annually, that is an effort that needs to reach across partners and even countries.

Meet Bob. He is a piping plover who received this nickname while being banded by CWF Wildlife Biologist Emily Heiser in 2012 as part of a SUNY-ESF research project in New Jersey. This past weekend was a big day for Bob. Three of his chicks reached the fledgling state – this milestone of flight is the metric for a successful breeding season.
Things have not always gone so well for Bob. In 2012 his mate was killed by a predator and he couldn’t incubate their eggs alone, so the nest was abandoned and he didn’t find a new mate. In 2013 Bob and his new mate (Kelly) were down to their last remaining chick when a ghost crab snatched and dragged it down its burrow. We dug the chick out, but it died soon after in rehab. In 2014 Bob and Kelly’s chicks died quickly at the hands of an unknown predator. In 2015 a nest camera painfully showed Bob’s chicks being eaten by a fox just after they hatched and were still lying in the nest bowl.
Flash forward to this year and Bob was part of the last piping plover pair left nesting in Avalon, once a thriving breeding site with as many as eight pairs. His long-time mate Kelly left him for another male at Stone Harbor Point, but he found a new mate and finally they have met success. Given all that has happened to Bob, you can see why we are happy for him (and Emily) today!
Sadly, this five year “drama” is not an especially unusual story for piping plovers. Their existence, especially here in New Jersey, is seemingly “against all odds”. In addition to the predators, they face a multitude of threats, direct and indirect, such as human disturbance as a result of heavy recreational use of beaches, habitat loss and degradation, and flooding, to name a few. Each year CWF and a host of partners throughout coastal New Jersey mount an extensive effort to protect piping plovers and other endangered beach nesting birds such as least terns and black skimmers. Without this active protection and management these birds would probably disappear from most of our state’s beaches.

So far our weekly beach nesting bird updates have focused on statewide trends, but this week we are going to feature one special pair of piping plovers.
The story actually starts in the summer 1989…Ronald Reagan had just left the White House and the Berlin Wall would fall a few months later. It was also the last time a piping plover nested on the miles of oceanfront beaches at Island Beach State Park. That all changed in May of this year, when a pair of plovers was observed exhibiting breeding behavior at the southern portion of the park close to the inlet jetty. Eventually they laid four eggs, a cage was erected around the nest to protect it from predators, and right on schedule over the July 4th weekend, four itty-bitty chicks emerged. A week later, three chicks have survived the daily battles with predators (i.e. fox, crows, gulls) and a heat wave. The story isn’t over yet, we won’t know for another 3 weeks or so if they survive to the stage where they can fly, which is our metric for success.
Regardless of the outcome, this pair being at Island Beach State Park symbolizes an interesting point in New Jersey’s conservation efforts to recover this federally threatened and state endangered species. 2016 marks the 30th anniversary of federal listing for the Atlantic coast population of piping plovers, and with it extensive management to aid recovery. Those management efforts have led to varying results in New Jersey; our population has swung from a low of 92 pairs to a high of 144 pairs, but mostly settling in around 120 pairs. We are currently in a slight upswing, but the bottom line is New Jersey is a tough place for piping plovers to successfully breed – it represents a convergence of all the significant threats the birds face.
Why did piping plovers suddenly show up at Island Beach State Park again this year? Well, we may never know for sure, but we do think Hurricane Sandy probably had a part in it. While it was wrecking destruction up and down the Jersey Coast, Hurricane Sandy was also creating the kind of sparse, open habitat where piping plovers prefer to nest. Some of that was created at Island Beach, and soon after Sandy, we noted some “prospecting” plovers at the park. Nothing came of that, but meanwhile piping plover action was heating up just a little bit south on LBI at the Holgate Unit of the Edwin B. Forsythe NWR and just across the inlet at Barnegat Light. The storm created especially good conditions for piping plovers in those locations, including a giant “overwash” at Holgate, which in turn attracted more and more plovers, which produced a “bumper crop” of young fledglings. Barnegat Light only had one remaining plover, but it produced well above average numbers of fledglings for several years in a row.
Quick biology lesson…piping plovers exhibit very strong site fidelity, so the adults tend to come back to the same site year after year, often the same patch of beach. That includes their young, but they have to forge their own territory as existing pairs fiercely defend their established territory. This year we have seen a bump from one to four pairs in the Barnegat Inlet area and one of the new breeding birds was born last year at Holgate (we know that from bands now being placed on the birds by researchers). With Holgate reaching capacity, the returning young are looking nearby for other places to nest. The Island Beach plovers are not banded, but the banding in this area is new in our state, so they might also be young from previous successful nests at Barnegat Light.
At the moment New Jersey has high concentrations of piping plovers at Sandy Hook and the Forsythe NWR, over three-quarters of the state population occurs at these federal properties. They are performing well at these sites for now, but habitat conditions change quickly along the coast and real recovery has to happen over a wider geographic area. For any significant population rebound to occur, new sites need to be colonized, so the piping plovers at Island Beach State Park this year may be a small sign of that starting to happen.

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!
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!

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.
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.
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’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.

As we begin to wrap up our third year of the Shorebird Sister School Network, we are able to reflect on how far we have come in just a short time. In our first year, we started with just one class at Amy Roberts Primary School (Green Turtle Cay, Abaco, The Bahamas), led by teacher Jan Russell, which was paired up with a class at Ocean City Intermediate School (Ocean City, New Jersey), led by teacher Deb Rosander. We presented the students with information on the full life cycle of the Piping Plover, commonly referred to as “our birds” in New Jersey. Really they are residents of The Bahamas, spending over half their life on the warm sandy beaches surrounded by turquoise water. Piping Plovers in The Bahamas, in most cases, see less disturbance than what is experienced by plovers on their breeding grounds in the United States and Canada.
We not only focus on breeding, migration, and wintering of the plovers, but the importance of their habitat to a suite of species. In The Bahamas, the tidal flats used by the Piping Plovers are of huge importance to the ecological value and economy of The Bahamas, as the flats are also used by bonefish, conch, and shark species. We had both classes conduct similar projects — interpretive signs placed on the breeding and wintering grounds — using their writing skills and original artwork. The students also participated in field trips where they learned how to use spotting scopes and binoculars to find and identify shorebirds.
Three years later, we still are teaching our core lessons, but have vastly expanded on the curriculum and projects, as well as extending the program onto another island, Eleuthera, which is just south of Abaco. We now are working with Cherokee Primary in the settlement of Cherokee Sound (Abaco) and Deep Creek Primary (Deep Creek, Eleuthera). We have continued working for the last three years with Amy Roberts Primary School and Ocean City Intermediate School. Back in the United States, we have added a second class from Ocean City, as well as the Leeds Avenue Elementary School Environmental Club (Pleasantville, New Jersey) led by Mary Lenahan. We’ve added new components to the curriculum such as bird anatomy, foraging differences between species of shorebirds, invasive species, habitat assessments (including macroinvertebrates) and marine debris.
We continue to implement interpretive signs as a project with classes that are in their first year of the program, but have come up with new and exciting projects to keep the students (and teachers) motivated and engaged to continue participating as a sister school. For example, during the second year we worked with Amy Roberts, we removed 1,500 Australian pine (Casuarina spp.) from Green Turtle Cay as it degrades the habitat for piping plovers and other species. We created a Piping Plover activity book complete with crossword puzzles, word searches, and mapping activities designed mainly by the students at Ocean City Intermediate School, Leeds Avenue Elementary School, and Amy Roberts Primary School. Because Cherokee Primary and Deep Creek Primary are new to the program this year we hope to have their students create interpretive signs, while the second and third year students in the Program may develop PSA-type videos this year and pen pal letters to their respective sister schools in the United States.
Throughout the year, each class receives one or two classroom lessons and a field trip. We keep busy during the few short weeks we have in The Bahamas; coordinating the field trips, conducting surveys, presentations, and working to continue to build and strengthen our existing relationships with partners, such as Friends of the Environment and local citizen scientists. This year, we’ve reached over 120 students in the program, both from the Bahamas and in the United States.
One of the most rewarding aspects of the Shorebird Sister School Network is that we are able to provide lessons to the some of the same children throughout multiple years in the program, which strengthens the conservation messages we are trying to instill in the upcoming generations. We hope to foster a greater appreciation for wildlife, especially for the Piping Plover and its habitat, and inspire students to help now — and later on in their lives as adults — ensure the recovery and survival of the bird for years to come.

The wintering segment of the 2016 International Piping Plover Census has just wrapped up in the Bahamas. This marks six winters of my own involvement with piping plover conservation work in the Bahamas – starting with the last international census in 2011 – so I thought it would be a good time to reflect on the changes I have observed in the years between the censuses.
First and foremost, we now know much more about how many piping plovers winter in the Bahamas and where they are located, including some areas where there are particular high concentrations of piping plovers and other shorebirds. This knowledge is due to the significant increase in survey effort put forth by partners in the Bahamas during the census, but also surveys conducted by Bahamas National Trust and National Audubon Society, as well as our own work at Conserve Wildlife Foundation of New Jersey (CWF), in the years since 2011 to supplement the earlier surveys and better understand how piping plovers use the sites.
This is demonstrated by the results of the 2016 census. As just one example of how this extra research paid off, in 2011 when we visited Casuarina Point on Abaco for the census, we knew from local birders and e-Bird that piping plovers were frequently seen there, but not that it was only for a narrow window during low tide to forage, nor that depending on wind conditions or disturbance, they could be at another more remote flat across Cherokee Sound. So in 2016, we had surveyors in place at the correct tide AND in both locations at the same time, thus allowing us to record 26 piping plovers, instead of 0 in 2011. Using similar information gathered across the island we found 178 piping plovers in 2016, compared to 76 in 2011 (and 82 on Eleuthera in 2016 vs. 30 in 2011).
Even with some oversights like those, the 1066 piping plovers tallied in the 2011 census revealed that the Bahamas was one of the most significant wintering locations for piping plovers, second only to Texas. And with band resight data, we now know that the Bahamas is THE most important winter location for the Atlantic coast population (as compared to the Great Lakes and Great Plains populations). Although the final count for the 2016 census is not complete yet, it has already topped the 2016 figure and will account for a good part of the remaining unknown wintering birds and locations. New surveys in the Turks and Caicos, more intensive surveys in Cuba, as well as the Southeast/Gulf Coast U.S. (which is critical for all three populations of piping plover) should make this the most comprehensive and informative survey to date.
While improved census results are important, one may reasonably still ask how the census is going to translate into better conservation. The Bahamas is a good example of what can be done with the data — last year the Bahamas government set aside the Joulter Cays as one of a series of new national parks, to a large degree based on its importance for shorebirds, especially piping plovers, as a result of information initially gathered from the census and follow-up surveys. This marked the first time shorebirds played a significant role in such a designation, so this is a watershed event for shorebird conservation in the Bahamas (and the Caribbean).
I have noticed other “sea changes” in attitude on a smaller scale. When I first visited the Bahamas (Abaco) during the 2011 census, aside for some birders, piping plovers were little known by the public there. Now when I come, I am recognized as the plover guy and piping plover bumper stickers can be spotted around the island on golf carts and trucks. There is even a new post card, entitled “Birds of the Bahamas” that has a piping plover side by side with a flamingo, the national bird. And there is refreshingly little of the rancor we sometimes have in the states over their protection – the habitats piping plovers use in the Bahamas, especially tidal flats, are also important for valuable resources, such as conch and bonefish, and other marine species, so protecting them is less of a conflict.
The important role the Bahamas plays in the piping plover life cycle is now much better known by the public and other stakeholders. Many of the participating partners have not only provided technical shorebird expertise during the surveys, but worked hard to provide education and outreach towards a long-term conservation goal. One area my colleague Stephanie Egger and I are most proud of in this realm is our Shorebird Sister School Network, where we pair up schools and students in the Bahamas and in New Jersey, using piping plover migration as the link. Now in its third year, this project is working to create a new generation of young conservationists (and piping plover lovers)!
This is not to say our work is done. There is still more to learn, a banding study is being conducted to help us better understand survival compared to other wintering (and breeding) regions, more detailed aspects of site fidelity, and how birds move around sites within islands. Still, piping plovers are no longer a novelty in the Bahamas as was largely the case when I first came in 2011. The challenge over the next five years will be how to harness the increased awareness and knowledge to aid recovery of this endangered species.
A special thanks to Friends of the Environment, who have been our piping plover partner on Abaco from the beginning, please check out all the great work they do! Also to the Disney Conservation Fund and The National Audubon Society for funding, as well as Bahamas National Trust for other support and the conservation work they do in the Bahamas in general. Thanks to the U.S. Geological Survey, sponsors of the International Piping Plover Census, for supporting CWF’s inclusion in the surveys. Thanks to Rolling Harbour Abaco for setting up the Abaco Piping Plover Watch this winter to help us keep track of piping plovers and raise local awareness. Thanks to those who participated in the CWF led 2016 census on Abaco and Eleuthera: Brendan Toote, of the College of the Bahamas, Michelle Stantial, of SUNY – ESF, Pam Prichard, and CWF’s own Stephanie Egger and Emily Heiser. And finally, thanks to our local citizen scientists on Abaco who participated in or provided valuable knowledge for the 2016 census, especially Ali Ball, our “super” volunteer!
