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

by Todd Pover, Beach Nesting Bird Project Manager

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.

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

by Todd Pover, Beach Nesting Bird Project Manager

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.

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

by Todd Pover, Beach Nesting Bird Project Manager

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.

NEW JERSEY’S HIDDEN COAST – EPISODE 4

By Emily Hofmann, Assistant Communications Manager

Periodic storms are an unavoidable fact of life when you live along the coast. In rebuilding after Hurricane Sandy, we realized we needed a new way of thinking about beach restoration on New Jersey’s Hidden Coast – the Delaware Bayshore. Storms like Sandy and Katrina have shown us that the most effective way to control storm surge is to follow Mother Nature’s lead. The restoration of tidal wetlands, or marshes, will help absorb the brunt of coastal storms, acting as a buffer between the beaches and the mainland.

 

 

Learn more about marsh restoration – one of the key components to rebuilding coastal beaches – in the fourth episode of our video series.

 

A new episode of our video series “New Jersey’s Hidden Coast” will air every two weeks throughout the summer! Catch a glimpse of the bay, the horseshoe crab at the center of the bay’s system, and the incredible relationship between horseshoe crabs and migratory birds, like the red knot. We will reveal the real value of horseshoe crabs, the challenges to the ecosystem, and the potential for a thriving regional economy along the Bayshore. We will show Hurricane Sandy as a catalyst for decisive action and the work being done to rebuild the area for both people and wildlife.

 

Over the next several weeks, we will explore the use of “living shorelines” instead of bulkheads and the central importance of marshes to the marine ecosystem. We will discover the on-the-ground, grassroots efforts of the community to build oyster reefs alongside veterans. And we will examine the future of the Bay and the work that needs to be done to preserve our conservation successes thus far.

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

by Todd Pover, Beach Nesting Bird Project Manager

While the July 4th holiday weekend is the celebratory peak of the summer season for beachgoers, it is not a joyous time for beachnester staff or beach nesting birds. The holiday brings an extra crush of people out on the beaches at the most critical time for our endangered nesting shorebirds. Nearly all the species – piping plover, least tern, black skimmer, and American oystercatcher – are at the peak of their breeding seasons in late June/early July so the holiday is sometimes a “make it or break it” day or in the case this year a long weekend.

So our beachnester staff went into overdrive this weekend, working extra hours to guard and monitor nesting sites, both day AND night. Fireworks, the symbol and heart of any July 4 celebration, are especially problematic. The disturbance from the fireworks themselves can be an issue, but the extra large crowds (and typically extra boisterous behavior) on the beaches at night can be a deadly combination for the beach nesting birds. Personal fireworks in proximity to nesting colonies also have to be “policed” by our staff and volunteers.

With this year’s holiday now just passed, it looks like our efforts largely paid off. There were areas where protective fence was vandalized and had to be restored, and some minor bird losses were documented this weekend, but it was fortunately minimized this year. With that in mind, we are sending an extra special thanks out today to the dedicated beachnester staff members and volunteers, not just in New Jersey but across the entire breeding range, for their hard work this weekend and throughout the season.

The bird’s still have several weeks to go before we’ll know if the season was a success overall (stay tuned for that news), but “holding down the fort” on July 4 is one more challenge that is now in the books for this year.

THE “GREAT” WHITE  SHARK: MISTAKENLY BLAMED FOR THE NJ SHARKS ATTACKS OF 1916?

By Michael Davenport, Wildlife Biologist & GIS Manager

The New Jersey shark attacks of 1916, during which four people were attacked and killed and one injured along the New Jersey shore by one or more sharks, are usually blamed on the great white shark. The great white is definitely a dangerous shark and has been responsible for more fatal shark attacks on people than any other species. However, since one of the attacks occurred upstream within the Matawan Creek, another species (the bull shark) has recently received some scrutiny as being, if not the culprit in all the attacks, at least responsible for some. The bull shark, unlike the great white, is known for frequently entering freshwater, traveling far upstream in some rivers.

However, Matawan Creek is actually a saltwater tidal creek and is certainly deep enough for a white shark. Eyewitness accounts of individuals who witnessed a shark within the creek in 1916 also describe a shark which is more similar to a white rather than a bull shark. The white shark (either multiple individuals or one shark) remains the chief suspect for at least some, if not all, of the 1916 attacks.

Regardless of whether this is the species which terrorized the East Coast during the summer of 1916, this can be a deadly species due to their size, power, and sharp serrated teeth. This species specializes in preying on large marine mammals, primarily seals and sea lions. Even a “nibble” or “taste” can be fatal to a human.

THE NURSE SHARK: A SHELLFISH-EATING BOTTOM-DWELLER

By Michael Davenport, Wildlife Biologist & GIS Manager

The nurse shark isn’t your typical-looking shark. It doesn’t have the torpedo-shaped body of the fast swimming mako or great white, nor the large mouth in front. Instead, it has a somewhat flattened body with a small mouth located under it’s head. This species is specialized for feeding on the bottom of the seabed, primarily on shellfish. It’s teeth are not intended for tearing flesh, but for grinding hard prey, such as crabs.

The nurse shark is a relatively docile species which is not generally considered dangerous to humans. They are easily approached and popular with SCUBA divers. However, if they are provoked (grabbed by a diver) they will bite in defense. Their mouth has a powerful suction for catching prey and they have been known to hold on after biting, so it’s best to leave them alone.

THE DUSKY SHARK: LATE TO MATURE & SLOW TO REPRODUCE

By Michael Davenport, Wildlife Biologist & GIS Manager

The dusky shark provides a good example of why shark species and shark populations around the world are in trouble. Dusky sharks have been known to live up to 40 years. Females aren’t ready to start breeding until they’re about 21 years old. Within that 21-year time, they face dangers from other predators, such as larger sharks. In a natural setting, free of human interference, enough sharks survive to be able to reproduce fast enough to compensate for those sharks which don’t reach adulthood.

Due to overfishing, dusky shark populations are only a small fraction of what they once were. They are often hunted for their fins or they are caught as by-catch when commercial fishermen are targeting other species. Due to their slow growth, late maturity, and low rate of reproduction, the species simply cannot replace its numbers fast enough. Because of this, the dusky shark is classified by NOAA Fisheries as a Species of Concern throughout its range and the species has been prohibited in both commercial and recreational fisheries since 2000. Though it has no legal conservation status in New Jersey, it is still illegal to take, possess, land, purchase, or sell them.

THE SAND TIGER SHARK: PREDATORS EVEN BEFORE THEY’RE BORN

By Michael Davenport, Wildlife Biologist & GIS Manager

Sand tiger sharks look ferocious. With a mouth agape with rows of outward-pointing needle-sharp teeth, they are often regarded as deadly man-eaters. However, their appearance doesn’t tell the whole story. Although they have been known to attack humans, they are not man-eaters. Those needle-sharp pointed teeth are very poor tools for cutting through mammal flesh (unlike the great white’s serrated triangular teeth which are perfect for cutting through mammal flesh). Sand tigers are primarily fish eaters and attacks on humans are often made either when the shark is approached to closely or if a diver happens to be spear fishing and the shark is attempting to catch the speared fish.

Sand tigers are very ferocious when it comes to eating fish. So ferocious, in fact, that they are known to feed on their siblings even before they are born. Sand tigers give birth to live young. The mother sand tiger has two uterine sections within her body in which up to 50 young sand tigers will develop. As they grow, the larger, stronger sand tiger pups will nourish themselves by feeding on the others. Eventually, only the two young will then be born, already born killers.
