19,077 Red Knots Counted – The Most Seen in New Jersey in a Decade

An Update on the 2015 Delaware Bay Shorebird Project

By: Dr. Larry Niles, LJ Niles Associates LLC

Despite the threatening forecast of a cold drizzle and strong winds, our team persevered to complete the first bay-wide count of this season. On the New Jersey side of Delaware Bay, we counted 19,077 red knots – the most seen in the state in a decade. With Delaware’s shorebird team recording 2,000 knots along their entire shoreline, the total knot count of 21,077 is not far from the 24,000 seasonal maximum of the last three years.

This is good news in either of two completely different ways. One explanation is that perhaps most of the knots have already come to the bay. If so, they are in good time to make weight and are getting close to an on-time departure for the Arctic. The alternative is that even more will arrive and we will exceed our counts of the recent past. Good weights promise good Arctic production; more knots offer new hope.

The numbers of ruddy turnstones (12,295) and semipalmated sandpipers (56,788) are also close to the seasonal maxima counts of the recent past, so they too may soon brave the long flight to their Arctic homes. Our cannon-net catches of turnstones, sanderlings and knots point to weights building quickly.

The weather conditions play with our expectations. For the last few days, high westerly winds have generated beach-pounding waves all along the Cape shore. Its north/south orientation is perfectly perpendicular to the strong winds, and the wind-generated waves shut down horseshoe crab spawning. This forces the birds to seek shelter and better egg densities elsewhere.

 

Right from the start, the disappearance of the shorebirds we had been seeing intrigued us, for a good wildlife mystery gets consumed in this team like a good bottle of beer. Within hours, Mark Peck and Gwen Binsfeld found the knots south of where we would have expected. The knots, turnstones, sanderlings, and semipalmateds were comfortably riding out the wind storm on the vast, sandy intertidal flats in front of Sunray Beach and Villas. We haven’t seen birds gathering in numbers here since the early 2000’s.

But back to the count. We found shorebirds all along the Bayshore with three areas of concentration. The first was the aforementioned Villas flats. The second was in the Pierces Point to Reeds Beach area, with most in the more southerly portion of the sector. “Not-knots” (mostly semipalmated sandpipers) were seen there in big numbers during the boat survey by Yann Rochpault, Christophe Buidin and Tom Baxter. They saw 12,000 shorebirds along this mostly unpopulated shoreline.

But the real shorebird wonderland of the bay continues to be Egg Island. Few people see this this vast intertidal marsh, and fewer still appreciate its wonder. Egg Island – actually a peninsula – juts miles out into the bay, nearly to the shipping channel. The marsh cradles one of the most diverse bird faunas of the mid-Atlantic. All along its mucky eastern flank, short-billed dowitchers, dunlin, semipalmated sandpipers, black-bellied plovers, and semipalmated plovers comb the eroded banks for crab eggs drifting in the water column from better crab breeding sites. The crabs themselves attempt to breed in the overhanging edges of the spartina marsh, a lost cause; however, because the muck lacks oxygen and the eggs cannot develop. This is bad for crabs but good for shorebirds because most of the eggs end up on the sod banks, easy prey for shorebirds.

But this week, the wonders of Egg Island overwhelmed us. Our team – Humphrey Sitters, Phillipa Sitters and this blog’s author – wove along the shallow shoreline in our intrepid 17-ft Carolina skiff, counting thousands of shorebirds – 8,226 knots, 4,125 ruddy turnstones, 3,000 sanderlings, and 21,000 semipalmated sandpipers. The flocks swirled around the   peninsula’s sandy western shore, alighting, then flying, and then alighting again. It was a shorebird dance that was a wonderful sight for increasingly tired-out shorebird scientists.

13,000 Red Knots on New Jersey’s Delaware Bay

An Update on the 2015 Delaware Bay Shorebird Project

By: Dr. Larry Niles, LJ Niles Associates LLC

We had about 13,000 knots on the New Jersey side of the Delaware Bay (an additional reported 2,000 on the Delaware side of the Bay). Yesterday, we suffered strong NW winds in excess of 20 kts and the birds virtually disappeared. Our daily survey turned up about 6,000 knots, the rest we suspect, finding refuge in Egg Island and Goshen Marshes or with a flyover to Delaware.

 

We will know where they went today. The team will comb the Bayshore for shorebirds with a coordinated ground, boat and aerial survey. The birds gain weight in good time and we expect the first Arctic lift-offs by the 26th. At the current rate, most of the Bay’s population will be off to the Arctic by the 30th.

2015 Horseshoe Crab Spawn and Shorebird Migration on Delaware Bay

An Update on This Season’s Horseshoe Crab Spawn and Shorebird Migration, Ten Days In

By: Dr. Larry Niles, LJ Niles Associates LLC

Thousands of shorebirds now fill Delaware Bay’s beaches and marshes in a determined effort to regain lost reserves with free-for-the-taking fatty eggs of the horseshoe crab. The crab spawn began ten days ago and has gained momentum over the last week as the volume of eggs grows like a well-funded savings account. The eggs surface as each new female crab digs up egg clusters laid by other crabs or as wind-driven waves pound the always-fluid sandy beaches. At least 8,000 red knots slowly get fat on the eggs scattered on New Jersey’s Delaware Bay beaches.

Both crabs and birds are the beneficiaries of the increasing number of beaches that are highly suitable for egg-laying. In October, 2012, Hurricane Sandy ravaged two-thirds of New Jersey’s best crab-spawning beaches, its strong westerly winds lifting sand and spreading it far from the sea’s edge. Left behind was a jagged sod bank, completely unsuitable for horseshoe crab breeding. The mucky sod starves eggs of oxygen or gasses them with hydrogen sulfide, the by-product of decaying mud.

 

The American Littoral Society, Conserve Wildlife Foundation of New Jersey, the U.S. Fish and Wildlife Service and the National Fish and Wildlife Foundation came to the rescue, restoring many of these beaches to a condition superior to that before Sandy. The restoration team even repaired damages that predated Sandy — beaches with tons of rubble that entrapped crabs in nasty concrete, killing them by the thousands. Now beaches like Thompson’s Beach and Fortescue Beach join the growing number of delicate sandy strands that provide excellent spawning habitat.

Thompson’s Beach Before and After Restoration

This week, eggs can be found in many places on the New Jersey side of Delaware Bay, and the birds have the freedom to move to those that best suit them. Earlier this month, strong northwest winds drove red knots from the Reeds Beach area to other, more northerly, beaches that saw good crab spawning — beaches that also provide shelter from the winds. Now that the wind and sea have calmed, the birds have returned to the Reeds Beach area, less than 20 miles away, and have resumed gorging on the plentiful eggs that built up in their absence.

If one were to look for any cloud on the Delaware Bay shorebird horizon, it would lie in the lack of any evidence of horseshoe crab recovery. The current, reduced, population of crabs spawned eggs in great numbers early this May because of a spike in the water temperature, a consequence of unusually warm weather.  So far the promise of this early spawn is holding, and crabs continue to spawn in good numbers. But will it hold until the end of May?

Crabs in Slew

If not, the readers of this blog will witness the outcome. The graph below, developed by long-time team-member Dick Veitch tells the story of a past egg failure. In the early 2000’s, although the population of shorebirds had not yet declined to its current number, the crab population had already fallen to its current number, crushed by the onslaught of a poorly regulated fishing industry.  In those years, all the horseshoe crabs that could spawn had finished by the third week of May and egg densities on the bay plummeted. The birds crammed into the few beaches with eggs like Mispillion Harbor, Delaware, so densely that the beach reeked of off-gassing urinary ammonia.

 

But the number of eggs there was not sufficient to feed the still-large shorebird populations and birds failed to reach a weight – about 180g for red knots — suitable for their journey to the Arctic and subsequent breeding. Where once 80% reached the “good” weight, only 5% did in 2003 (see the second graph).

Percentage of Red Knots Reaching 180 Grams
Percentage of Red Knots Reaching 180 Grams

The percentage has improved thankfully, but only because the number of shorebirds have fallen over the last 10 years, bringing a balance of sorts. Hopefully, with the new beaches, the new protection afforded by the red knot listing and the growing number of volunteers taking part in conservation of the crab and birds, this kind of disaster is behind us.

We shall see.

2015 Delaware Bay Shorebird Project Continues!

Another Season of the Delaware Bay Shorebird Project Underway

By: Dr. Larry Niles, LJ Niles Associates LLC

The value of a shorebird stopover like Delaware Bay can be seen in the shaky cam movie by this author.  Red knots – some recently arrived after a grueling 6,000-mile flight over 6 days of continuous flying – arrive on the Bayshore desperate for food. Over the last 10,000 years, the species has evolved to fly directly to the Bay to feed on the eggs of the horseshoe crab.

The 450-million year-old crab – which is actually in the spider family – crawls ashore and lays pin-sized eggs about 6 inches deep in the sand. When there are many crabs, as here on Delaware Bay, one crab often unearths the eggs of another. Thus they leave millions of fatty eggs on the surface, offering an energy-rich, soft feast for the starving birds. In turn, we get to watch the birds racing for an egg ‘hot spot’!

The birds often arrive beyond depleted. A normal weight for a knot is 130 grams.  Many arrive on Delaware Bay below 100 grams, the equivalent of a human in the throes of profound starvation. But when the birds fly north from the coast of northern Brazil, there’s no turning back. Once they go, they must go all the way.

This year, migrating shorebirds faced a freak tropical storm that could have forced them out to sea, far off-course.  In severe cases, some birds with no remaining fat reserves even metabolize their own muscles, like airplanes throwing out vital equipment to stay aloft. Storms can also prevent birds from lifting off on migratory flights. They are capable of detecting atmospheric pressure changes and can just stay put until a storm passes. We think this is what happened this week when a storm, followed by a strong cold front and consequent northwest winds, prevented a movement north.

The sum of these challenges was lower than normal shorebird numbers during the first week of the stopover. The Heislerville impoundments support a good number of short-billed dowitchers and dunlin, but these species usually arrive earlier than the others and probably came in ahead of the adverse winds. Yet there are very few ruddy turnstones, sanderlings and semipalmated sandpipers on the Bay.

The one exception on the Bay is the red knot. At first, we thought that only about 1,000 red knots had arrived in and around Reed’s Beach. Then Jerry Binsfeld and Peter Fullagar, Canadian and Aussie members of our team, found an amazing 7,000 knots at Gandys Beach on the northern Bayshore in New Jersey. Very likely, these are short-distance migrants, coming in from wintering areas in Florida, Georgia and the Caribbean.

Our catch results support this working hypothesis. The knots we caught at Fortescue were at higher weights than normal for this early part of the season, which would be expected if fewer very thin long-distance migrants were part of the average.

The Return of Bald Eagles in New Jersey

Conserve Wildlife Foundation Releases New Story Map: “The Return of Bald Eagles in New Jersey”

By: Brian Henderson, GIS Specialist

Bald Eagle Story Map

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 Map displays 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!

2015 Delaware Bay Shorebird Project Begins!

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?

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.

Lysate Industry

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.

Celebrate International Migratory Bird Day 2015!

Restoring Critical Delaware Bay Habitat for Migratory Shorebirds

By: Kelsey Lawler, Spring 2015 Intern

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!

Traveling the Flyway in Search of Piping Plovers

CWF BIOLOGIST HEADS NORTH TO CANADA ON CONSERVATION MISSION

By: Todd Pover, Beach Nesting Bird Project Manager

 

Grey Flag EP, a marked Canadian piping plover  and one of the stars of the weekend.
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.

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.

Horseshoe Crab Tagging and Monitoring in Raritan/Sandy Hook Bay

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.

 

Take action to help protect these over 250 million year old creatures:

Bayshore Regional Watershed Council is recruiting volunteers at:

  • Cliffwood Beach in Aberdeen Township
  • Conaskonck Point in Union Beach
  • Leonardo Public Beach in Middletown Township
  • The mouth of Many Mind Creek in Atlantic Highlands
  • Plum Island at Sandy Hook National Recreation Area

Dates and times for the 2015 monitoring program are:

  • Monday, May 4, 2015 at 8:30pm
  • Monday, May 18, 2015 at 8:30pm
  • Tuesday, June 2, 2015 at 8:30pm
