South Reeds Beach Oyster Reef Event Filmed by Local Delaware Bay Producer
By: Lindsay McNamara, Communications Manager
A record number of Red Knots were counted on New Jersey’s Delaware Bay this year, in part because of innovative restoration projects like our South Reeds Beach oyster reef.
Over 130 volunteers and veterans worked alongside Conserve Wildlife Foundation and American Littoral Society to establish a near-shore whelk shell bar at South Reeds Beach in Cape May Court House on the Delaware Bayshore in early April.
Shorebirds, like the federally listed Red Knot, depend on an uninterrupted supply of horseshoe crab eggs when they stopover in Delaware Bay during their migration. In recent years, countless horseshoe crab eggs have been lost because of the devastating storms that swept away the beaches they depend on.
The oyster reef was built to prevent sand loss from wind-driven waves. The approximately 200-foot project will test whether the reef bars help reduce beach erosion and create calmer water for spawning horseshoe crabs.

Researching the Causes of Chick Loss in Piping Plovers
By: Emily Heiser, Biological Assistant
Double the fun! We were able to capture both birds in one try at this nest!
I often find myself contemplating the lives of Piping Plovers. What happened to that nest? Why did they choose that exact spot to lay their eggs? Why did those chicks disappear? Where will they go for the winter? As wildlife biologists and conservationists who spend hours and hours each summer watching them, we tend to question every aspect of the Piping Plover’s life cycle. These questions also push us to work harder and do more for this species, which is so imperiled throughout its range.
This summer, thanks to the extraordinary support of the US Fish and Wildlife Service, the New Jersey Division of Fish and Wildlife, and along with the blessings of Conserve Wildlife Foundations’s own Beach Nesting Bird Project Manager Todd Pover, the State University of New York College of Environmental Science and Forestry (SUNY-ESF) received the green light to proceed with a chick mortality study of Piping Plovers along New Jersey’s coast.
Funded by the National Fish and Wildlife Foundation, SUNY-ESF’s Jonathan Cohen and Michelle Stantial have teamed up once again to make some plover magic happen here in New Jersey. Having had the great privilege of working for this dynamic duo in the past, I am over the moon to be able to assist them once again.
Nest camera being readied so it can keep a watchful eye on the nest for predators at all times.
The big question of this study is simple on the surface: what are the causes of chick mortality? The methods of finding those answers are much more complex. On April 15th, we kicked off another fantastic field season collecting data from Barnegat Light to Cape May. In order to determine the causes of chick loss we first need to locate nests, determine nest fate, track the adults, and then finally track the chicks. We hit the ground running and so far there are 26 active nests between all of our study sites! One of the most interesting parts of this study pertains to the cameras we are placing at a number of nests.
Our high tech plovers are now enjoying a 24/7 monitor that never bothers them, but is always watching. On more occasions than I can count, I have come across a nest that was lost in the past 10-24 hours.
We make our best guess as to what happened based on the evidence…Was it a flood? An avian predator? A mammalian predator? What happened?! It’s frustrating, but now we can know with certainty and we can learn much more about the threats Piping Plovers face on their breeding grounds.

Another important component of this project revolves around the banding and nano-tagging the adults. It is essential to the study that we are able to determine survival and movement of the adults. So far we have been able to band 24 adults, with 10 of those also receiving a transmitter. There are two telemetry towers between our study sites. These towers are able to pick up multiple radio-tagged birds and track of them day and night.
Interestingly, in a previous study developed by SUNY-ESF adult female Piping Plovers spent much of the evening away from the nest and leave the males to do all of the nocturnal incubating! The most advantageous part of these towers will, in theory, be able to tell us what happens to the chicks. Each chick will receive a tiny transmitter and as depressing as it may seem, those towers can tell us the speed and trajectory a chick was carried away from the site by a predator.
My vote was to give the chicks an iPhone and shoot me a text when they were in danger, but that doesn’t seem to be possible…yet.
I am not sure there will ever come a day when I am not pondering the lives of Piping Plovers, but I believe that science and research will continue to supply more answers. I believe that this particular study will contribute to a greater understanding of these birds, and on a personal level, I believe it will enable me to become a better steward and manager of all New Jersey’s beach nesting birds.
We look forward to bringing spectacular photos and updates whenever we can, so stayed tuned for more pondering of plovers!
Conserve Wildlife Foundation Releases New Story Map: “The Return of Bald Eagles in New Jersey”
By: Brian Henderson, GIS Specialist
Today, Conserve Wildlife Foundation of New Jersey (CWF) announced the release of “The Return of Bald Eagles in New Jersey” a Story Map that provides a new way to visualize the increasing number of bald eagle pairs nesting in New Jersey over time.
For years, CWF has worked closely with the New Jersey Endangered & Nongame Species Program (ENSP) to track and restore the bald eagle population within the state. It has been a rewarding experience for all involved to witness the return of bald eagles to the garden state, and now the public can appreciate the scope of their return as well.
The recovery of bald eagles nationally and in New Jersey is fairly well known, but some may not realize that as recently as the mid-80’s there was only a single pair of nesting bald eagles in all of New Jersey. The ban of DDT, combined with restoration efforts by ENSP biologists, resulted in population increases to 23 pairs in 2000, 48 pairs by 2005 and 82 pairs in 2010.
In 2014, there were a record 146 active bald eagle pairs nesting in New Jersey. This year, 190 nesting territories are being monitored and currently 88 chicks have been reported at 52 nests; it is still early in the season so we don’t have a count for all nests yet.
“The Return of Bald Eagles in New Jersey” Story Mapdisplays the locations of all the known active bald eagle nests in New Jersey from 1985-2014. Users can choose to view the nests active in a single year or over a longer period of time. By choosing a one year interval and beginning in 1985, it’s possible to watch as nests multiply from a single nest in Bear Swamp to densely populating the Delaware Bay coast and spreading across the southern portion of the state and eventually into almost every county of New Jersey. In 2014, the only counties in New Jersey without an active bald eagle nest were Essex and Hudson.
The Story Map also highlights “featured” nests, or nests of special significance, including the Duke Farms nest which has been featured on a webcam since 2005 and the Millville nest where a juvenile eagle was fitted with a GPS tracking device in 2014. These featured nests include more information, pictures and links to pages that explore related projects in greater depth.
As the bald eagle population has reached record numbers in New Jersey, the raptors have expanded into non-traditional parts of the state, providing more and more people with a chance to glimpse this iconic species. This map highlights the ongoing success of conservation efforts and illustrates that whether you realize it or not, you’re never very far from a bald eagle nest in New Jersey!
Another Season of the Delaware Bay Shorebird Project Underway
By: Dr. Larry Niles, LJ Niles Associates LLC
Our 2015 Delaware Bay Shorebird Project began on one of the hottest early-May weekends in memory. Clive Minton, an English-expatriate Australian, and I began the project with an early morning survey of each bay beach – Reeds, Cooks, Kimbles, Pierces, Rutgers, Norburys, Villas – dripping sweat and swatting biting gnats as though it was early June, not early May. The sudden burst of summer weather warmed the bay waters, triggering our first horseshoe crab spawn providing sufficient eggs for newly arriving birds.
The birds, on the other hand, followed a more normal schedule. We counted only 400 knots, a smaller number of ruddy turnstones and, surprisingly, no sanderlings. We know the birds are en route; Pat Leary in Florida and Fletcher Smith in Georgia report good numbers of knots, but the birds appear stuck because of the unsettled weather and the rare occurrence of a tropical storm making landfall in North Carolina over the weekend. Soon enough they will come.

The warm weather and the abundant crab spawn bode well for the birds – we want the early bird to gets eggs. But they point to one of the many difficulties facing the red knot and other shorebirds. Will the insidious effects of climate change unravel this elegant machine that provides horseshoe crabs eggs just at the time Arctic-nesting shorebird need them to fly on to their breeding areas?
Horseshoe Crab EggsHorseshoe Crabs Spawning
Our project is 19 years old and so provides a perspective virtually unique among wildlife projects. A long-running project of this kind has many advantages, not the least of which is the human family that has formed around our love of birds. We have nearly the same core team in 2015 as we did in 1997, losing and gaining a few team members as time marches on, but always maintaining an esprit de corp, a common purpose, a lasting bond. The shorebirds, the crabs and the many people who love the Delaware Bay owe a debt of gratitude to this team of intrepid researchers.

The project’s longevity also creates a perspective rare in the world of bird study. Over 19 years we have seen the collapse of the horseshoe crabs; the dramatic free fall of the red knot that resulted this year in a federal listing as Threatened; the rise of irresponsible commercial exploitation of the natural wealth of the bay; a devastating hurricane and more. And yet each year the birds arrive, the crabs spawn and our team coalesces from every corner of the world. Despite the problems and all the concern, the system persists.
But how long will the system persist?
The challenges faced by the birds grow every year. They cling to this amazing migratory bird like barnacles on a wooden boat. Crabs have not recovered from the devastating overharvest of 15 years ago. The international drug cartels still drain the blood of crabs for the valuable chemical lysate without any responsible management. All the while shorebirds, the red knot in particular, face growing threats from climate change: more frequent storms, destroyed coastal habitat, rapidly-changing arctic tundra habitats.
Herein lies the value of a long-term study. This season’s unprecedented early spawn and warm weather could be good or bad. Either way, by season’s end, the team’s dedication, skill, and plain hard work means we will know what happened and what it means compared to 18 other years.
Restoring Critical Delaware Bay Habitat for Migratory Shorebirds

Saturday, May 9 is International Migratory Bird Day (IMBD) 2015! It is time to celebrate and bring awareness to the spectacular event that is bird migration. Since 1993, IMBD has been serving as a celebration as well as a call to action for migratory bird conservation.
Conserve Wildlife Foundation of New Jersey has been doing their part for bird conservation. We have developed a range of programs to increase the numbers of endangered migratory birds, like the Red Knot, since their decline in the late 1990’s.
Red Knots use New Jersey’s Delaware Bayshore as a stopover for feeding after their long journey from the Arctic and South America. Delaware Bay plays a major part in the Red Knot life cycle, so we’ve focused our efforts on restoring this critical habitat. The Red Knot migration is timed to take advantage of the spawning of the horseshoe crabs that use the same beaches as breeding grounds. Their eggs provide a rich food source for the Red Knots at a time when they are in desperate need of nutrients.
We have been working to benefit both horseshoe crabs and the migratory shorebirds that feed on their eggs, like the Red Knot, through our beach restoration projects, oyster reef construction and monitoring projects. Since Superstorm Sandy, we have successfully restored over a mile of impacted horseshoe crab habitat. We’re working to further protect these beaches from erosion and to create calmer waters for horseshoe crabs through our oyster reef construction experiments. To learn more about our restoration work in Delaware Bay, visit RestoreNJBayshore.org.
Of course, we haven’t been able to do this work alone. Volunteers are one of the reasons why these projects are possible!
Celebrate International Migratory Bird Day by getting involved in migratory bird conservation:
Grey Flag EP, a marked Canadian piping plover and one of the stars of the weekend.
My trip to Canada this past weekend, completed a circle of sorts for me. Over the course of my two decade career studying and protecting Atlantic Coast piping plovers, I have traveled to nearly all of the breeding states in the U.S. More recently, I have expanded my work to their wintering grounds, visiting states in the southeast U.S. and extensively in the Bahamas. But there was one big gap in my piping plover conservation work beyond New Jersey – Atlantic Canada, which, by itself represents an entire recovery unit in the federal recovery plan.
“So you chase plovers around the world,” someone said to me in Canada this weekend. Well, not for the sake of just seeing them in different locations. What I am “chasing” is knowledge and partners. I am seeking information about to how we can improve our breeding program in New Jersey by observing what works (and doesn’t work) in other parts of the range and developing partners to help further conservation across the range.
The story of how I finally ended up in Canada illustrates just how connected piping plover conservation is on an international scale. This past winter, CWF’s Stephanie Egger and I resighted a number of marked piping plovers in the Bahamas. Among those were plovers with engraved flags indicating they bred in Atlantic Canada, marked as part of a long-term research project to try to determine survival, site fidelity, and wintering distribution, among other things. One of the plovers we observed was Grey E4, seen on a small quiet beach on Spanish Wells, Eleuthera. I dutifully reported the band the same evening we observed it and in a few hours the researchers responded it was banded as a chick the previous season in Liverpool, Nova Scotia. When I returned from field work the next day, I had an inquiry about the sighting from a small newspaper back in Nova Scotia, an unusual occurrence, especially so soon after reporting the band. A nice article resulted, a little excitement was generated, and that was the end of story for us on that banded bird.
At least it would normally be the end of the story. Over the course of the next few days and then weeks, I noticed that White Point Beach Resort, the breeding site where “E4” originated from, was frequently posting about the Bahamas resighting and in general about their plovers. After sleeping on it awhile, I finally decided to reach out to them; my curiosity was peeked about what was driving their enthusiasm. What I found out was that they genuinely love their plovers (of course, they do), but they are also interested in marrying conservation and commerce. Instead of it being an adversarial situation as often happens, a fear that having an endangered species would limit activities on their beach, the resort viewed the plovers as “value added” – something their guests would be interested in and maybe even come to the resort to experience.

And they recognized the bands as a way to tell and sell the story. I couldn’t agree more, the bands provide a means to promote piping plover conservation on a personal level through storytelling. Piping plover banding projects are never undertaken lightly; trapping and marking birds involves some risk, and the prime motive for banding always has to be in the name of research to aid management and recovery. But once the birds are marked, we have an opportunity to use them for other purposes as well.
Post and sign designating a piping plover breeding sites in Canada.
Having instantly bonded over our shared connection to E4, one thing led to another, and we decided to try to partner…in Canada, no less. It started small, but White Point Beach Resort reached out to the local piping plover community and research network, and eventually a whole weekend of activities was planned. May 3 was declared International Piping Plover Day and billed as a day for “banding together to celebrate partnerships.” Working in coordination with Bird Studies Canada, which oversees and implements the piping conservation and research projects in this region, an informative program, including updates on the Canadian banding project and breeding success in Nova Scotia, was presented as part of the weekend.
My role was to tell a little more of E4’s “story” and provide a big picture perspective that included the wintering and migratory portions of the piping plover’s life-cycle. Other highlights for attendees (and me) was a chance to view White Point’s resident pair of piping plovers, including Grey EP, who had just returned to the site to nest once again this year and is the “father” of E4. We even posted and fenced the nesting area of the resort’s beach.
Now that I have completed my travels across the piping plover’s entire Atlantic coast range, I have a flyway scale perspective of the conservation efforts and the challenges we all share. Ironically, the wider my view has become, the more I realize that in the end it comes back to the local view. Conservation works most effectively at the local level, the “stories” connect us on the local level, and we care most passionately about our local piping plovers. Another way of saying Think Globally, Act Locally.
It was an honor to be part of International Piping Plover Day in Nova Scotia this past weekend. I consider it something of a piping plover “diplomatic mission.” A special thanks to Donna Hatt and Wendy Coolen of White Point Beach Resort for organizing and hosting the event and to Sue Abbott of Bird Studies Canada for her coordination, as well as everything she does for piping plover conservation in Atlantic Canada.

Bayshore Regional Watershed Council Looking for Volunteers to Help Out Four Nights in May and June
By: Lindsay McNamara, Communications Coordinator

The Bayshore Regional Watershed Council (BRWC) is looking for volunteers to help monitor and tag horseshoe crabs in Sandy Hook and Raritan Bay this May and June. Since 2009, BRWC has been collecting hard data through their volunteer-driven monitoring and tagging program. This data is used to help analyze the population of horseshoe crabs in the region and better inform conservation efforts to protect them.
Lately on the Bayshore, the Council has seen a ratio of about 35 males per 1 female, which is a cause for concern. Why are there so few females? How will the population continue to survive in the region with such a low number of mature, female horseshoe crabs?
BRWC investigated the issue and found that New York State is harvesting about 100,000 horseshoe crabs a year from the Harbor. Female horseshoe crabs are frequently harvested because their eggs are used as bait for fishermen. Horseshoe crab numbers have dropped dramatically in New York area waters, BRWC thinks in part because of the harvest. According to the Council’s website, over the last 150 years, horseshoe crab populations have declined 90%. What can concerned citizens do to help protect the current population of horseshoe crabs in Sandy Hook/Raritan Bay from further decline?
Volunteering with Bayshore Regional Watershed Council is a great place to start. Volunteers monitor and tag horseshoe crabs on four nights (alligned with the new and full moon and the tides) through May and June on Sandy Hook/Raritan Bay. The volunteers record clusters, single females, single males, swimming pairs, and other data points on tally sheets at five different locations on the Bayshore. The recordings function as a sampling of the population; volunteers monitor an area of 1,000 feet by 6 feet on the beach. BRWC volunteers can see anywhere from 10-125 horseshoe crabs a night, depending on the site.
Adult horseshoe crabs are also tagged. The tag displays a New Jersey Division of Fish and Wildlife phone number that can be called if the horseshoe crab is seen again. These tags and calls by the general public help biologists to better understand horseshoe crab behavior and where they go when they are not spawning. BRWC suspects that older horseshoe crabs return to the ocean out past the continental shelf, while younger horseshoe crabs stay in the bay. Volunteering will help the Council collect more data to analyze these observations and trends.

Today, Friday, April 17 is Bat Appreciation Day 2015. Join Conserve Wildlife Foundation in celebrating the beloved bats of New Jersey today and every day.
Bats are one of the most beneficial animals to humans. They provide important economic and ecological benefits from eating the bothersome pests like mosquitoes, to devouring the insects that also destroy our agricultural and forest land.
Bats save us millions of dollars in damage each year and play essential roles in keeping populations of night-flying insects in check. Just one bat can eat up to 3,000 insects in a short period of time, and large colonies catch tons of insects nightly.
Unfortunately, these amazing animals continue to face many threats including habitat loss and the devastating disease, White-nose Syndrome. White-nose syndrome, alone, can kill 90-100% of bats in affected caves.
Conserve Wildlife Foundation works hard to protect New Jersey’s bats through on-going research, education and outreach. We provide homes for evicted bats with our Bats in Buildings project as well as collect and record valuable data about the state’s bat population with our Summer Bat Count project, and our acoustic bat surveys.
New in 2015, Conserve Wildlife Foundation will conduct surveys to learn more about the summer distribution and habitat of Northern long-Eared Bats, a species listed under the Endangered Species Act this month.
Also this month, the Bat Cam bats have returned for the spring and summer! We are excited to follow this colony throughout the season and highlight special moments of their lives.
Today, on Bat Appreciation Day, consider supporting Conserve Wildlife Foundation’s Bat Project. Help us help New Jersey’s bats not only survive, but thrive in the Garden State.

Oyster Reef Build on South Reeds Beach a Huge Success
By: Lindsay McNamara, Communications Coordinator
Photo by: Lindsay McNamara
Over 130 volunteers and veterans worked alongside Conserve Wildlife Foundation of New Jerseyand American Littoral Society to establish a near-shore whelk shell bar at South Reeds Beach in Cape May Court House on the Delaware Bayshore on Saturday, April 4, 2015. The shell bar was built to prevent sand loss from wind-driven waves. During the “Shell-a-Bration,” an approximately 200-foot oyster reef was constructed offshore to test whether the reef bars help reduce beach erosion and create calmer water for spawning horseshoe crabs.
“We are rebuilding the habitats of Delaware Bay to strengthen its ecology, its communities and its economy. This reef approach will be a key technique which we will try to expand around the Bayshore,” stated Tim Dillingham, American Littoral Society Executive Director.
The South Reeds Beach Oyster Reef is one of the many projects that American Littoral Society and Conserve Wildlife Foundation are working on to restore the ecology and economy of the Delaware Bayshore, thanks to generous funding by the National Fish and Wildlife Foundation.
“The project focuses on creating resiliency in Delaware Bay beaches while improving their usefulness to horseshoe crabs. We have a great challenge: how do we create a reef to protect against damaging Bay storms without stopping horseshoe crabs from getting ashore to breed,” said Dr. Larry Niles, a biologist who leads the beach restoration efforts for Conserve Wildlife Foundation of New Jersey and American Littoral Society, and has studied Red Knots for three decades. “This project is an experiment to help us do both,” he added.
Shorebirds, like the federally listed Red Knot, depend on an uninterrupted supply of horseshoe crab eggs when they stopover in Delaware Bay during their migration. In recent years, countless horseshoe crab eggs have been lost because of the devastating storms that swept away the beaches they depend on.
“The time-honored migration of Red Knots to reach the eggs of these ancient horseshoe crabs is a wildlife spectacle of global significance right here in Delaware Bay,” explained David Wheeler, Conserve Wildlife Foundation of New Jersey Executive Director. “Red Knots come to New Jersey’s Delaware Bay from as far away as the southernmost tip of South America to feed on horseshoe crab eggs. It is vital that we promote coastal resiliency projects like this one to support the largest population of horseshoe crabs in the world, and the human communities of the Delaware Bayshore alike.”
The new oyster reef will attenuate waves but still allow for horseshoe crab breeding. In existing areas where crabs can breed without interruption, like creek mouths protected by sand shoals or rock jetties, egg densities can exceed ten times the egg densities on unprotected beaches.
The projects are being funded by National Fish and Wildlife Foundation (NFWF) through their Hurricane Sandy Coastal Resiliency Grants Program, and are being developed in partnership with U.S. Fish and Wildlife Service and New Jersey Division of Fish and Wildlife.
“The Delaware Bayshore is a perfect location to demonstrate how communities benefit from their connection to a healthy natural resource base – for fishing, boating, wildlife watching and tourism,” said David O’Neill, National Fish and Wildlife Foundation Vice President of Conservation Programs. “The economies of Bayshore towns have historically been intertwined with the bay. And with the NFWF Hurricane Sandy grant, American Littoral Society and Conserve Wildlife Foundation of New Jersey are already restoring shorelines to make Bayshore natural resources and communities more resilient for the future.”
Event guests enjoyed a barbecue and oysters, and family-friendly activities like a “Green Eggs in the Sand” Easter Egg Hunt. In addition, local leaders and biologists spoke to the attendees about the oyster reef project at a mid-day “Whelk-come.”
