Tag: black skimmer

by Todd Pover, Senior Wildlife Biologist

New Jersey Fish and Wildlife has released their annual reports for the 2024 beach nesting bird season and the results were mixed. Piping plovers had one of their worst seasons on record in New Jersey since federal listing in 1986. Least terns also fared poorly, while black skimmers and American oystercatchers posted more promising breeding results.

According to the state report, piping plovers recorded their lowest population in New Jersey in 2024, at just 89 pairs, and statewide productivity was poor, as well, at just 0.54 chicks fledged per pair, third lowest on record. The state’s piping plover population has fluctuated greatly in the past five years, reaching 137 pairs in 2021, close to the peak of 144 pairs, only to now fall to the historic low. While the low pair count is concerning enough in its own right, this year’s poor productivity also doesn’t bode well for next year, as productivity is often strongly linked to short-term population changes for piping plovers. Productivity during the 2024 breeding season was well below both the long-term New Jersey average (1.01) and the federal recovery goal (1.50). Furthermore, productivity has been poor over the past several years, putting future population increases at risk.

Pair counts dropped along nearly the entire Jersey coast, with Sandy Hook having one of the most dramatic losses from 34 pairs in 2023 to 14 in 2024. The population loss there is especially troubling given Sandy Hook was once a stronghold for the state, its piping plover population has been trending downward from just over 50 pairs about a decade ago. Productivity was also very poor at Sandy Hook in 2024, just 0.50 chicks per pair, again this site used to be one of New Jerseys’ productivity hotspots for piping plovers. Holgate, a Unit of the Edwin B. Forsythe NWR, and one of the sites monitored by CWF, continued its recent trend of having the most breeding plovers in the state, with 48 pairs or 54% of the state’s population in 2024. Unfortunately, it experienced especially bad productivity, producing just 0.35 chicks per pair. One of the notable highlights in the state was the Barnegat Light Habitat Restoration Area, a site CWF has had a lead role in creating and maintaining, where 5 pairs produced 10 fledgling or 2.00 per pair.

Although New Jersey’s least tern population was surprisingly robust this year with 1,436 total adults recorded, two concerning recent trends for this colonial species continued in 2024. The number of colonies dropped to just 11, the lowest since 1976. Productivity for the state’s least terns was poor, only 146 fledglings were recorded. The highlight was the TNC South Cape May Meadows site, where 80 fledglings were produced.

Black skimmers were also only present at just a few colonies in New Jersey in 2024 – three known active colonies at Holgate, Horseshoe Island, and Stone Harbor Point – the lowest number of colonies documented since 1976. On the other hand, their population, with 2341 adults, was on the high side of the past 20-year range and they had a very good season productivity-wise. Strong results were seen at all three colonies, resulting in nearly 1000 fledglings produced overall. Horseshoe Island had the state’s largest colony with 1,347 breeding adults, helping demonstrate the importance of the recent conservation efforts at this relatively new site.

American oystercatcher data are more difficult to assess, as only a portion of the state’s breeding population is monitored, with most of the marsh nesting breeders, which account for a significant portion, left unmonitored. At 155 pairs in 2024, those oystercatchers regularly monitored – primarily the sandy beach strand population – continued their steady long-term growth trend over the past two decades or so since regular monitoring began in New Jersey.

Productivity was also strong for the oystercatchers in New Jersey in 2024, clocking in at just over 0.50 chicks fledged per pair, which is the recovery target. As a long-lived species, annual productivity goals are lower for American oystercatchers, compared to the shorter-lived piping plovers. Among the highlights for American oystercatchers in New Jersey this year were Holgate with 53 pairs, the most in the state, producing 0.79 fledglings per pair and Horseshoe Island recording an average of 1.50 fledglings from 16 pairs, both of these being sites CWF helped monitor and manage.

This year was an especially challenging one for beach nesting birds in New Jersey. Most of the species fared poorly on a statewide basis, and even though they can withstand periodic down years, several trends are worrisome to biologists and wildlife managers.

The state’s piping plover breeding population remained the same as last year with 118 pairs, which is also about the same as the long-term average since federal listing. However, productivity was just 0.53 chicks fledged per pair, the second lowest since federal listing and well below the levels believed necessary to grow the population. Of particular concern, productivity has been low for three consecutive years after a number of years of above average success. Productivity is one of the main drivers of population (up or down) and small populations are especially sensitive to even small changes, so it is expected that the population is likely to drop over the next few years, further stagnating plover recovery in the state.

Meanwhile, there was a record number (53) of breeding pairs of piping plovers at Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, that is monitored by CWF through a cooperative agreement with the Refuge. This positive trend, almost a four-fold increase has occurred since Superstorm Sandy enhanced the habitat for plovers at the site, has been an ongoing highlight for the state in recent years. Nonetheless, it has not been accompanied by similar increases elsewhere in the state, so it has not led to any statewide recovery. Productivity for the large concentration of piping plovers at Holgate was above the statewide average in 2023 but the lowest level over the past decade, so it was also a down year for this site, where expectations typically run high that it will help boost statewide productivity.

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.

As we approach the official, and unofficial, beginning of summer, many warm-weather loving citizens of New Jersey are pulling out their swimwear, purchasing their SPF and preparing to flock to the Jersey Shore and contribute to some of the worst traffic seen around the country. It’s important, however, to take a step back and remind oneself to be certain that their beach activities will not affect the livelihood of other creatures that are just trying to survive in the only habitat that can support them. Both Memorial Day Weekend and July 4^th holidays occur during the season that beach-nesting birds are incubating eggs and raising chicks. This makes for some conflict between beachgoers and coastal wildlife, so it’s necessary to bring more awareness to the presence of the birds and the importance of giving them space.

Beach-nesting birds are called just that because they depend on undisturbed, sparsely vegetated, and stabile coastline to breed, lay eggs, and raise their young. They nest directly in the sand and their eggs are sand-colored and camouflaged against predators. This also makes them difficult for people to see, and without proper monitoring and protection measures, they can wind up being run over or stepped on. Small chicks, like those of the piping plover, are tiny and very mobile shortly after hatching. While the parents do their best at corralling their chicks and keeping them away from people, sometimes the chicks wind up under a beachgoer’s umbrella seeking shade or wandering too close to potential danger. Anyone with small children would understand the difficulty in keeping their kids from running off somewhere they’re not supposed to go, especially when they can have up to four of them at once. The chicks must forage to feed themselves, so being very mobile increases the likelihood of them finding small invertebrates to eat.

Earlier this year we announced that Horseshoe Island, which recently formed just offshore near Little Egg Inlet, would be seasonally closed to the public to benefit nesting and migratory birds. The closure from March 1 to September 30 is part of a plan put forth by New Jersey Fish and Wildlife and the Edwin B. Forsythe National Wildlife Refuge, who were granted rights by the state to manage the island and its adjacent intertidal waters. CWF played a key role, helping monitor bird activity on the island this year through a cooperative agreement with the Refuge. With the closure period coming to an end, we are happy to report that it was a successful season, especially for colonial nesting species such as the state endangered black skimmer. A full report of the results will be issued later this year but in the meantime, NJFW has released a video about Horseshoe Island. The video features CWF biologists Todd Pover and Emmy Casper, who helped lead the on-the-ground monitoring effort.

NEW, WEEKLY UPDATES FROM NEW JERSEY’S BEACH NESTING BIRD PROJECT TEAM

by Todd Pover, Beach Nesting Bird Project Manager

There are many ways to gauge success for our beachnesting bird project. We look at how well our management tools work, the effectiveness of our partnerships, and how well our educational efforts work, to name a few qualitative measures we use. At some point, however, it comes down to cold hard numbers, how well did the birds do in a particular season and over the long-term. We are at that point in the season, and for the most part, I am happy to report it has been an excellent breeding year. I will caution that these are still preliminary figures, some quality checking of the data needs to be done before they are final, but the trends are clear.

First up are piping plovers. We will come in at ~115 pairs statewide, up modestly from the 108 pairs in 2015, and the second consecutive year of an increase after hitting our historic low of just 92 pairs in 2014. So, we have climbed back closer to our long-term average, but there is still room to improve. The really good news is our productivity this year – close to a statewide record at 1.37 chicks fledged per pairs – puts us in the position to continue our population increase. If trends hold, because piping plovers demonstrate high site (or region) fidelity, when we produce a lot of fledglings, our breeding population rises in the next year or two. With three straight years of well above average fledgling rates for New Jersey now in the books, our prospects look good in the short term for our breeding population levels.

Least terns and black skimmers, which nest in colonies, sometimes numbering hundreds (or even thousands), are more challenging to count and assess, but we had at least modest success this year for both species. As is typical, our least tern colonies were variable, with some completely failing and others being highly productive. The Monmouth County region, one of our strongholds for least terns in New Jersey, didn’t have one colony that was a standout but most of them had at least some success. In South Jersey, our two largest colonies at Holgate (EB Forsythe NWR) and Seaview Harbor were very successful and helped make up for losses and failures at other colonies. The majority of our state’s black skimmers are concentrated in one large colony at Seaview Harbor, and although skimmers are our latest nesters (so the season isn’t quite over for them), they appear to have been very successful there, which means a good season overall for the state.

We also track American oystercatchers, although only for the portion that nest on the barrier beaches and spits. Because the biggest percentage of oystercatchers in the state nest on back bay and marsh islands, we cannot determine true statewide population or productivity levels, but the population on the beach habitat appears to be rising in recent years. Typically breeding success is lower for oystercatchers on the beach habitat due to high levels of human disturbance and predators, but productivity has been relative high the past two years. Of particular note this year was Stone Harbor Point, where a record number of 27 pairs nested and produced over 30 fledglings.

The reality is our beachnester staff works just as hard in years when the birds do poorly, as when they do well like this year, but it is SO much more rewarding when we have a good season. So as we wrap up the season, we are all feeling in a bit of a celebratory mode now!

NEW, WEEKLY UPDATES FROM NEW JERSEY’S BEACH NESTING BIRD PROJECT TEAM

by Todd Pover, Beach Nesting Bird Project Manager

 

For this week’s installment, I thought it would be fun to have you tag along with me on a day in the field, so you can get a sampling of what goes into our beach nesting bird program. Let’s call it, “A Day in the Life of a Beachnester.”

 

Today it is an early 4 am rise to beat the beach crowds and heat, as we are banding black skimmers at our Belmar colony. This is the first time our program has banded skimmers –  it is a collaborative effort with other organizations/agencies in both New York and New Jersey – we hope to find out more about their survival, longevity, and movement, both local and long distance. Everything goes well, we are able to corral and band about 35 chicks in less than an hour. This part of the day represents the science portion of the beach nesting bird project, science for the sake of study and a better understanding of our birds, but more importantly to gather information to help us manage and recover endangered species.

 

With no time to spare, it is now off to Leonardo along Sandy Hook Bay where CWF is hosting a summer wildlife experience for kids. No surprise, I am the guest today to teach the kids about beach nesting birds. I explain why piping plovers and American oystercatchers are at risk, and then give them a chance to use a high powered birding scope to try to read bands I have placed on decoy birds. We definitely have some budding biologists in the mix. Education is key to our project, unlike other endangered species that mostly live out of sight or reach, beachnesters spend the breeding season on the same beaches visited by millions of tourists and residents. If they are going to learn to “share the shore” with our endangered birds, outreach is essential.

 

Next up is a stop at Seven Presidents Oceanfront Park, one of our important nesting areas in Monmouth County. For most of the season we are erecting and adjusting fence to protect nesting areas, but today we are working with the park to reduce the fence, as many of our birds have successfully nested and started to leave the area. First we count and locate any remaining least terns – these surveys are the base of our project – we need this data to track population trends and seasonal productivity as metrics of progress towards recovery. Before we remove any fence at this site, we also conduct surveys of sea beach amaranth, an endangered plant that shares the beach with our nesting birds. We locate a few plants and that dictates how we readjust the fence, the plants need protection from trampling by beachgoers or vehicles used by the park to maintain their beach.

 

 

Coordination with municipalities or other land owners that host beach nesting birds is a critical part of our project, as their activities can impact nesting success as much as beachgoer’s recreational use of the beach. So there is one more stop today to assess whether a maintenance request can be granted in a way that won’t put birds at risk. That done, it is time to start the two hour drive back to our office in Cape May County. I am ready for a nap, but no luck, as the truck becomes a mobile office to take care of other unattended business (while someone else drives of course). There are calls with several other towns, check-ins with our seasonal staff members that are spread out all along the coast, and finally dealing with a broken down vehicle (not ours fortunately) and a person who refused to take their dog off a nesting site.

 

Back at the office, it is one last check of email, entering a little bit of the data we collected today, and finally time to head home. Every day is a little different, but this day has been a good cross-section of the range of things we do on the project. It is tempting to think we just pop up fence and signs and hope the birds do well, but protection and recovery of our endangered beach nesting birds requires a comprehensive strategy addressing all the factors that impact nesting success.

CONGRATULATIONS, FRANCESCA BUCHALSKI AND BILL DALTON!

by Lindsay McNamara, Communications Manager

Earlier in 2016, Conserve Wildlife Foundation launched the “For the Love of Wildlife” Photo Contest. Our photography contest was meant to showcase the love for and need to protect the endangered and threatened wildlife that call New Jersey home. We encouraged youth and adult photographers across the Garden State to submit photographs in the following categories:

• New Jersey’s Rarest Residents: Endangered, Threatened, and Special Concern Wildlife Species Only
• The Garden State: New Jersey Landscapes
• Experiencing Nature: People Enjoying the Outdoors
• Wild New Jersey: All Animals in the Garden State

We were blown away by the amount of submissions we received! Over 1,470 entries were counted! New Jersey wildlife photographers, CWF board members and staff poured over the entries to choose our winners. Today, we are thrilled to announce both first place winners.

First Place: Francesca Buchalski
Allentown, New Jersey
Praying Mantis

Francesca was so happy to have won our contest! She shared more about the image and her passion for photography with CWF: “I took that photo at the Cape May Meadow during last year’s fall hawk migration festival. My mom and I are avid birders, and we love going to the migrations in Cape May! We were bringing up the rear on a guided walk, and just as we started walking down the path through the reeds, I heard ‘Wows!’ and ‘Cools!’ up ahead. As we caught up, we saw that everyone was looking at a praying mantis perched on a man’s telephoto lens! I had my camera with me to photograph birds, but that was an opportunity that couldn’t be missed! I thought it was pretty interesting and ironic that the man couldn’t photograph the praying mantis, even though it was on his camera (he couldn’t stop laughing), and it posed there for a long time. It was a great way to start the walk!

 

“I’ve only been photographing wildlife for about 3 years, just for fun. I started off by taking pictures of the birds that came to our feeders, and now I bring my camera on all of my birding adventures. As for my favorite New Jersey species…that’s a tough one! I think I would have to go with the osprey; they’re so charismatic in their coloring, hunting habits, and cool ‘opposable’ talon. I also really enjoy how easy it is to observe them by boat; whenever I think about the wetlands or the back bays of New Jersey, I automatically think ‘osprey.’ They also have such a great comeback story, its almost impossible not to love them!

 

“A close second would be the horseshoe crab; I find it simply incredible that they have remained unchanged for millions of years, and that so many migrating shorebirds depend on them. And who can forget their incredible immune system and blue blood! I also love how you can learn about and help horseshoe crabs by participating in hands on counting, tagging, and flipping walks (my mom and I have done some of those, and they’re such great experiences!)

 

“New Jersey has such an amazing array of wildlife, and sadly, so many people miss it amid all of the big cities; big thanks to everyone at Conserve Wildlife [Foundation] for helping to promote New Jersey’s wildlife and keep them around for years to come!”

First Place: Bill Dalton
Interlaken, New Jersey
Black Skimmer

Bill was so pleased to have won our contest. He said he is “truly honored to have [his] ‘Sky Skimmer’ photo selected as the grand prize winner from such a prestigious organization.”

 

Bill explained to CWF, “I once read that a photographer’s definition of luck is: Preparedness over opportunity = LUCK! That was certainly the case when I photographed the skimmers at Forsythe on a early spring morning. On a previous visit, I saw a mature peregrine falcon perched at sunrise not far from the observation tower. I returned a day or two later with the proper equipment for low light, high speed photography, with hopes to get early light shots of the peregrine. The falcon was there but I noticed 6 to 10 black skimmers feeding about 50 yards from my location. The light from the predawn sky and clouds reflected perfectly on the windless water’s surface. I took about 50 shots but one shot caught the skimmer in exactly the right position. The line between sky and water vanished! The camera should get all the credit, I just pushed a button! I’ve been a nature photographer (hobby) for decades. My first camera back in the 70’s was a Minolta SRT 101. Boy has photography come a long way since the days of only film!

 

“I love to kid people by telling them I’m an endangered species. By that, I mean, I was born and raised in Monmouth County. One of the most important goals in [CWF]’s mission statement is, ‘educating everyone who lives in New Jersey about our shared wild heritage and our shared responsibility to protect it.’ We’ve come a long way in accomplishing those goals but so much more has to be done.

 

“I must admit being a born and raised Jersey Shore boy that my favorite species is the osprey. I vividly remember back in the 1950’s asking my dad while driving down a shore road in Monmouth County, why the power company men were knocking down bird’s nests that were atop of the poles! Those nests were ospreys and the nests on the poles were considered a nuisance! Years later I am proud to have been partly responsible for one of the first osprey nesting programs in Monmouth County. I convinced the company I worked for to enter into an agreement with the NJDEP to relocate a nest from the Keansburg pier to our location in Union Beach. At that time ospreys were on the threatened and endangered species list.

 

“The transfer of the nest was successful and at that time (1987) it was the most northern osprey nest in Monmouth County. Now I see nests in dozens of locations throughout the county! The osprey is truly an example (along with many other species) on how educating the public about our wildlife heritage worked!

 

“My work has been wildly published over the years including leading magazines, books and educational publications. National Geographic has published my work several times, most recently in their book, ‘Sublime Nature: Photographs That Awe and Inspire.’ Once again, thanks to the judges and staff of the Foundation for this wonderful award.”

Conserve Wildlife Foundation Partners with National Wildlife Refuge to Collect Data on Beach Nesting Birds

Posted by: Lindsay McNamara, Communications Manager

 

Did you know barrier island beach makes up approximately 2% of the Edwin B. Forsythe National Wildlife Refuge? This area is the most productive for beach nesting birds. The federally threatened piping plover and other species such as least tern, black skimmer, and a species of special concern, the American oystercatcher, nest on Holgate Beach. The refuge closes the Holgate unit from April 1st to September 1st every year to provide undisturbed nesting habitat for these important species.

 

Not only is it important to protect nesting habitat for the birds, but it is also important to provide education opportunities to the public. Each summer, the refuge relies on volunteers during the summer months to talk to the public about the beach closure and bird management, and answer any general questions about Forsythe Refuge.

 

This year, Conserve Wildlife Foundation of New Jersey partnered with the refuge to assist in the collection of nesting data. “In the past, refuge staff has done all the beach nesting bird monitoring,” said Refuge Manager Virginia Rettig. “This year we are very excited to be working with our partners to monitor the population status of these birds. The work they are doing, combined with the data they collect, will improve our understanding of beach nesting birds on Forsythe Refuge.”

 

“Holgate provides highly suitable undisturbed natural habitat for at-risk beach nesting birds, especially piping plover – a rarity along the otherwise highly developed and recreated New Jersey Coast,” said Todd Pover, CWF Beach Nesting Bird Project Manager. “Maximizing productivity at this site is a high priority for regional and range-wide recovery efforts.”

 

Edwin B. Forsythe National Wildlife Refuge protects more than 47,000 acres of sensitive wetlands, marshes, and coastal habitats along the New Jersey shore. It is one of the most important habitats for migrating waterfowl and shorebirds east of the Mississippi River.

Assessing the damage to coastal wildlife and their habitat

By Stephanie Egger, Wildlife Biologist

As we all know Hurricane Sandy caused severe damage and devastation to New Jersey residents, homes, and their businesses, but we must not forget that wildlife can also suffer from the impacts of a hurricane.  CWFNJ’s Beach Nesting Bird Project Manager, Todd Pover, Alfred Breed, CWFNJ Field Technician, and myself, conducted wildlife/habitat assessments on beaches from Brigantine to Cape May after the storm.  Our nesting sites further north in Ocean and Monmouth Counties were still not accessible at that time to evaluate.  We assessed nesting habitat for beach nesting bird species, especially Piping Plover as well beach/inlet habitat used by migratory shorebirds, particularly American Oystercatchers.

As expected, many of our nesting sites and sites that are also used by migratory shorebirds for roosting were hit hard by Hurricane Sandy, losing a great deal of sand and suitable habitat.  However, in some locations such as Stone Harbor Point and North Brigantine Natural Area, the storm scoured out areas with too much vegetation which is good for beach nesters as they prefer sparsely vegetated areas. Sand was also pushed back into the dunes to create blowouts and overwash areas that may serve as additional habitat.  Many of the areas seem to be very low lying now from the loss of sand and might be more flood prone which could impact the beach nesters in the spring.

We also observed migratory songbirds, golden-crowned kinglets, which were taking shelter and flittering through the back dune/bayberry habitat right after the storm.  This was a good reminder of the value of New Jersey coastal habitat for songbirds as they migrate down the coast.

As part of our assessment, we conducted American Oystercatcher surveys as a significant number use New Jersey beaches for roosting during the fall and winter.  Luckily, approximately 900-1,000 American Oystercatchers were still using our southern coastal inlets after Sandy, about the same number of birds observed the week before the storm.  Thanks to funding from the National Fish and Wildlife Foundation we were already conducting fall surveys for American Oystercatchers and in the position to compare their numbers before and after the storm.

Only time will tell if the habitat will build back up enough in time for the spring as the birds begin to arrive for the nesting season or if it will have lasting impacts on migratory bird species. We hope to conduct further assessments to gain a better understanding of the short- and long-term impacts to wildlife from Hurricane Sandy and how that may affect conservation and recovery effort for these species moving forward.
