Researching Beach Nesting Birds at Edwin B. Forsythe National Wildlife Refuge

Posted on July 2, 2015 by CWF

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.”

CWF Field Technician Jesse Amesbury tracking piping plovers at Holgate with his scope.

“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.

Six Beautiful Butterflies that Call New Jersey Home

Posted on June 16, 2015 by CWF

A Closer Look at Six At-Risk Butterflies Found in the Garden State

By: Kathleen Wadiak, Wildlife Conservation Intern

New Jersey is home to a number of butterfly species as diverse as the different habitats throughout the state. Whether you live by the shore, a forest, or open fields, you can find a few of these species during their flight period, which usually takes place during the summer months. While it is no secret that the state can be home to well-known butterflies such as the Monarch, here are six butterflies that also call New Jersey home.

Baltimore Checkerspot

The best time to see a Baltimore checkerspot is early June to early August. This medium-sized butterfly a wingspan of about 1 ½ to 2 ½ inches. They are black with an orange border and speckled with white and orange markings. Checkerspots can be found in the northern half of the state in wet, stream-fed meadows consisting of mostly tall herbaceous growth. White turtlehead is a necessity in its habitat as it is the food source for developing caterpillars. The checkerspot’s unique environmental needs make it particularly vulnerable to habitat destruction and fragmentation.

Compton Tortoiseshell

Compton tortoiseshell butterflies have a flight period of March to November, during which they can be found in northeastern New Jersey in mixed and deciduous forests. In the forests, they make use of shelters created by tree cavities and nearby building eaves. Compton tortoiseshells can be identified by their orange-brown, black spotted wings with both the forewings and hindwings having a single white spot on the leading edges. The undersides of the wings are mottled gray brown with a small white “V.” With a wingspan of 2 ½ to 3 inches, they are a relatively large butterfly. The majority of this butterfly’s diet consists of rotting fruit and sap. Populations often fluctuate dramatically from year to year depending on habitat quality and climate factors.

Eyed Brown

Sightings of eyed browns occur from early June to late July in northeastern New Jersey, with most reports coming from Sussex County. They occupy open wetlands including sedge meadows, cattail marshes, and tall grasses alongside slow-moving streams where there are sedges for its caterpillars to feed on. Adults feed on rotting fruit, sap, and bird droppings. The eyed brown gets its name from its wings. About 1 ½ to 2 ½ inches across, they are pale brown, with the color darkening toward the body. On both sets of wings, there are black “eye” spots that are larger on the hindwing. The undersides of the wings are also pale brown, but have jagged lines running across them.

Hickory Hairstreak

Hickory hairstreaks can be seen from mid-June to early August in the northern half of the state. Their habitat consists of deciduous and second growth forests and adjacent fields. The forests in its habitat almost always consist of hickory trees, as they are the primary food plant of its caterpillars. Adult butterflies feed on the nectar of a variety of flowering plants including common milkweed, New Jersey tea, and white sweet clover. The hickory hairstreak is a relatively small butterfly with a wingspan of approximately 1 to 1 ½ inches. It is rarely seen with its wings open and is identified by the dark postmedian “dashes” and white outline on the underside of its grayish brown wings. On the hindwing, there is a pale blue patch that extends inward further than the adjacent orange and black spots. There is one tail on each hindwing.

Northern Oak Hairstreak

The flight period of the northern oak hairstreak lasts from mid-June to mid-July, during which they can be spotted in southern New Jersey oak forests and adjacent openings. Caterpillars of the northern oak hairstreak feed on the leaves of various oak species while adults feed on the nectar of flowers including New Jersey tea, milkweed, meadowsweet, and maleberry. The northern oak hairstreak is a small butterfly with a wingspan of approximately 7/8 to 1 ½ inches. The underside of the forewing and hindwing is gray-brown and has black and white, narrow postmedian bands, which form an “M” on the hindwing. There is a blue tail spot on the hindwing that is capped by orange and black. Each hindwing has one tail.

Rare Skipper

The rare skipper can be found along the southern coastal regions of New Jersey from May to September. Instances of rare skipper populations occur on a very local basis, and very little is known about the species. Their habitat consists of fresh and brackish wetlands along tidal rivers and marshes as well as abandoned rice paddies further inland. Caterpillar host plants include tall cordgrass in northern and coastal habitats and giant cutgrass in some southern wetland areas and abandon rice paddies. Adult rare skippers feed on nectar from wetland flowers such as swamp milkweed and pickerelweed. Rare skippers can be identified by their bright yellow-orange wings with a broad, dark border around the upper-side of the forewing and hindwing.

Be Terrapin Aware!

Posted on June 10, 2015 by Ben Wurst

Public urged to use caution while driving in shore areas this summer

Each year in late May and early June the annual nesting season for northern diamondback terrapins begins. This unique species of turtle is the only one to inhabit our coastal estuaries year round. They live exclusively in brackish water.

During this time of year, adult females emerge from the protection of their aquatic habitat to find suitable areas to lay eggs. They seek nesting areas with a sandy gravel type substrate that’s above the high tide line.

Throughout their range along the coast, terrapins face a variety of threats to their survival. Terrapin nesting habitat has been lost due to commercial and residential development, shoreline hardening and flooding which poses a greater threat to these limited nesting areas. Loss of terrapin nesting habitat along marsh systems put terrapins at greater risk of mortality as a result of increased time searching for adequate nesting areas (Winters 2013). Terrapins will utilize roadsides for nesting which increases the threat of being hit by motor vehicles. Roads are essential to our daily life but they often are barriers to wildlife, especially small critters like terrapins. Studies have shown that adult females have become less abundant and smaller from road mortality. (Avissar, 2006).

You can help terrapins several ways during the nesting season. Driving more cautiously from now until mid-July is a simple way to be more aware of terrapins crossing the roads. Nesting peaks during the full and new moon cycles and they’re more active during the high tide (less distance to travel on land to nest sites). We ask drivers in coastal areas to “Be Terrapin Aware” while driving in these areas. If you find a terrapin crossing the road use these steps to help it cross safely:

Stay safe. Never put yourself at risk! Make sure that you do not endanger yourself, or others, by walking into traffic.

When safe to do so, pull your car over and onto the shoulder, if possible. Turn on your hazard signals.

When safe to enter the roadway, approach the turtle and pick it up by grabbing its shell with both hands between its front and hind legs. HOLD ON – Terrapins have strong legs!

It is important that you move the turtle in the direction that it is heading. They are not always headed directly towards water. They will turn around if you put them in the wrong direction, so work with their instincts.

Place the terrapin off the road onto the soft shoulder (dirt or grass).

If you have a GPS or a smartphone then record your location and submit your sighting on our website.

Please do not move a terrapin long distances to “somewhere safe!” They have very small home ranges and moving them will only hurt them.

Rescuing a live terrapin (or any other turtle) from the road is a rewarding experience. It’s a great way to engage future generations in caring for our terrapins.

You can also help terrapins during the nesting season by supporting our new “Turtle Gardens” project. CWF, in partnership with the Marine Academy of Technology of Environmental Science, will develop and implement an educational initiative to promote terrapin nesting habitat enhancement. These “Turtle Gardens” will raise awareness of the benefit of living shorelines to terrapins and other coastal wildlife, as it relates to sea level rise and coastal flooding within the Barnegat Bay Watershed. Turtle Gardens for terrapins are patches of sandy nesting habitat above the high water line that are less susceptible to flooding. They also reduce the risk of road mortality. We will be having informational training sessions for those that would like to volunteer for monitoring Turtle Gardens or have property that would support a Turtle Garden. Information on these sessions will be announced in mid-June.

In addition, we will also be looking for terrapin sighting information with Project Terrapin in Berkeley and Lacey Townships in Ocean County as part of an initiative to fill in data gaps for this species on the mainland. If you see terrapins in these locations please report your sightings online.

2015 Delaware Bay Shorebird Banding Season Comes to a Close

Posted on June 2, 2015 by CWF

Delaware Bay Shorebird Project Team Finishes 2015 Banding Season

By: Dr. Larry Niles, LJ Niles Associates LLC

All our efforts to help shorebirds on Delaware Bay this year couldn’t have been better rewarded – nearly every red knot left the bay in good condition and in one of the earliest departures in the 19 years of the Project. We counted just over 24,000 knots in our aerial count of the entire Bayshore on May 26th. Just two days later, most had left and we could find only a few hundred, feeding on eggs like human shoppers feed on bargains at a half-price sale. By May 31st, virtually all were gone, along with the ruddy turnstones, sanderlings and semipalmated sandpipers. The beaches had an odd, deserted feel after the frenzy of the preceding days.

A good thing for birds and all those who love birds. The end of the shorebird stopover season also means the end of our shorebird team – at least for another year. All through the week, we lost team members—the North Americans left by car, those from other continents by air. Those who stayed shifted from research to manual labor: cleaning and storing equipment, closing up the rental houses, and reconnecting lost items to their owners.

Will our project continue? Now in our 19th year of work on the bay, one must recognize the realities of time’s passage. Clive Minton just cleared 80, and the rest of the original team will soon follow. This author, who started at relatively young 44, is now pushing his mid-sixties. Death visited our team this year with the passing of Allan Baker. Surely the rest of us will start “falling off the perch” as Clive is fond of saying.

Allan Baker, the Senior Curator of Ornithology and Head of the Department of Natural History at Toronto’s Royal Ontario Museum suddenly and unexpectedly died in 2014. His career included many significant achievements including early work that helped build a scientific case that overharvested horseshoe crabs caused the decline of red knot numbers. Photo from Wader Study.

And yet, all committed to return for a 20^th year. I worry over the fundamentals: our funding remains uncertain, the listing of knots as Threatened in the U.S. creates new regulatory hurdles, and N.J. politics seem to get more fractious every minute. Will there be a 20^th year of this project?

The answer starts and ends with the willingness of our team to do it again. It starts there because good ideas and projects always seem to find support; I know we will find a way. It ends there because this team provides the best chance of a strong scientific underpinning for protection. Our team includes some of the most important shorebird scientists in the world. At our dinner soirees (generously provided by Jane Galetto’s Citizens United team), Ph.D.’s are as common as empty beer bottles. It’s no surprise that conversation drills deep into conservation biology, behavioral ecology, migration physiology, stopover ecology, virology and many other subjects of interest to all our team, both scientists, old and young, and lovers of good science.

In many ways, the lives of our team members revolve around birds. The Delaware Bay Shorebird Project provides us a meaningful excuse to pull together once more. Our team members love birds, and do everything they can to help them. It’s been that way for 19 years, and it is this commitment that has led to this year’s results.

p180 red knots — This graph plots the percentage of red knots caught between May 26th and May 28th that have achieved at least 180 grams against the year of the catch. The 2015 result is still an estimate.

For the first time in 19 years, red knots left in a condition similar to the lucky ones migrating through before the fishing industry decimated horseshoe crabs in 1997. After that year, the populations of knots, turnstones, semipalmated sandpipers, and sanderlings fell off a cliff. For the last four years, however, the terribly reduced populations of shorebirds have been in rough balance with equally reduced number of horseshoe crabs breeding on the Bay. Consequently, the percentage of knots reaching the threshold weight of 180 g has climbed. (Knots need at least this weight to reach the Arctic and breed successfully.) From a low of just 5% making weight in 2003, they’ve clawed their way upward 30% in 2010, 50% in 2013 and now this year’s 90%.

Fat knot on the scale by Philippe Sitters

One must be cautious about the interpretation of this number but the catch of red knots on which it was based were truly fat birds! One weighed 226 grams, nearly 100 grams higher than its fat free weight. Whatever the figure it was a good season for both birds and the people who love them.

Fifth Graders from Across New Jersey Honored for Art & Essays on Rare Wildlife

Posted on June 2, 2015 by CWF

2015 Species on the Edge Art & Essay Contest Winners announced at Awards Ceremony

By: Lindsay McNamara, Communications Manager

2015 Species on the Edge Winners with representatives from CWF and PSEG

Today, Conserve Wildlife Foundation of New Jersey celebrated and recognized the winners of the 2015 Species on the Edge Art & Essay Contest, a statewide educational contest open to all fifth-graders, which encourages students to become wildlife biologists through their research and artwork on the endangered and threatened wildlife species in New Jersey.

“The vibrant artwork and passionate essays that we received from fifth-graders across the state reveal just how much these talented children poured their hearts into the Species on the Edge contest,” said David Wheeler, Conserve Wildlife Foundation Executive Director. “We are so thrilled to help connect the next generation of New Jersey conservation leaders with the natural world around them. Through their art and essays, all of us can see the wonders of nature – and the many challenges that we must overcome to help rare wildlife survive in our densely populated state.”

Students were asked to draw a picture of one of New Jersey’s 83 endangered and threatened wildlife species and compose an essay about how the animal became endangered and what can be done to help protect it. The Species on the Edge Art & Essay Contest encourages students to learn about local environmental issues, express their concerns for the world around them, think creatively about ways to improve it, and to consider how their actions impact the natural world.

Abby Miller, a student at T.P. Hughes Elementary School in Union County believes that it is important to protect wildlife in New Jersey because “everything deserves to be saved when they’re endangered.”

Bald Eagle from Mercer County Wildlife Center

This year’s ingenious group of winners was honored at an awards ceremony which was hosted at the New Jersey Education Association, in Trenton, New Jersey. The contest was sponsored by PSEG, NJEA, GAF, Atlantic City Electric, Church & Dwight, ShopRite and Six Flags Great Adventure. Mercer County Wildlife Center brought a live Bald Eagle to the event.

The statewide contest drew over 2,000 entries from across the state. Since 2003, over 10,000 children from across New Jersey have entered the Species on the Edge Art & Essay Contest.

Red Knots “Vote with their Wings”

Posted on May 29, 2015 by CWF

An Update from the 2015 Delaware Bay Shorebird Project Team

By: Dr. Larry Niles, LJ Niles Associates LLC

Clive Minton is fond of saying, “the knots vote with their wings” as a way of saying knots concentrate in the best places for knots. Of course it’s true, animals move to the habitats they find most suitable, nature leaves little room for anything but. Sometimes however, animals use a habitat only because they have little choice — in other words, they are making the best of a bad situation. The job of a good wildlife biologist is to understand the difference. Unfortunately, it’s often not obvious.

In all the places studied by this author — Tierra del Fuego, the Arctic, and many places in between — knots distinguish themselves as highly selective habitat specialists. There are many practical reasons for this: usually knots occur in flocks and thus require more space than many other species. More importantly, as they put on weight for their incredibly long-distance flights, they often push the limit of safe wing-loading (body weight to wing area). This makes them vulnerable to predators, both real and imagined. They need more flying space, more space for advance warning of a predator’s presence. They demand special roost habitats as well, especially night roosts that are free from disturbance and have good sight distances. Altogether they need more.

Red knots roost on a sandy spit on Egg Island, one of the largest contigous area of marsh in the mid Atlantic. Half of the bay's shorebird population roost on Egg Island and than feed on the various beaches around Fortescue. — Red knots roost on a sandy spit on Egg Island, one of the largest contigous area of marsh in the mid Atlantic. Half of the bay’s shorebird population roost on Egg Island and then feed on the various beaches around Fortescue.

In Delaware Bay, they need all this, but above all they need good horseshoe crab egg densities. In the mid 2000’s when shorebird numbers were high, the demand for those eggs exceeded the production from the rapidly diminishing crab population. Knots wandered the bay like homeless refugees. Competition for eggs drew tens of thousands of birds to places unused by knots in healthier times.

Mispillion Harbor, Delaware, for example, in some years supported much of the knot population in the Bay because it acts like a funnel-trap for crabs. Crabs wandered into the harbor through long stone jetties finding themselves in crab breeding heaven, sandy shoals in a closed space, free from wind-generated waves that normally leave them upside down. The egg-laying frenzy caused eggs to reach epic densities, thus preparing many shorebirds for their onward journey to the Arctic. Tens of thousands of shorebird packed into Mispillion Harbor in densities so high that one could smell ammonia off-gassing from the amount of bird waste.

But for knots, Mispillion left a lot to be desired. The same jetties that protect the inner harbor from wind-driven waves also provide low-flying raptors the cover to pounce on flocks before they can easily react. Fat birds make easy prey for peregrine falcons, who themselves struggle to keep up with the insatiable hunger of rapidly growing chicks.

But even as shorebird numbers fell in response to the reduced crab numbers, egg densities improved in other places. Knots reassessed their choices and voted with their wings.

This is why this year’s high count of red knots on the New Jersey side of the Bay are so important. Two days ago, Mark Peck, Joe Smith and I flew the entire Bay to count knots, ruddy turnstones and sanderlings. We counted over 24,000 knots, with 21,000 of these using the beaches managed by the many groups that take part in shorebird management on the New Jersey shore of Delaware Bay.

I am not saying this is a competition between two states — I’m saying the numbers serve as assurance that all our hard work is paying off. It’s a confirmation that the beach restoration projects, the Shorebird Stewards project, the reTURN the Favor crab rescue project, and more are bearing fruit. These coordinated strategies are led by Conserve Wildlife Foundation of New Jersey, American Littoral Society, Manomet Center for Conservation Sciences, New Jersey Audubon Society, the Wetlands Institute, Citizens United to Protect the Maurice River, The Nature Conservancy, as well as Downe Township, Maurice River Township, Middle Township and the Division of Fish and Wildlife, New Jersey Department of Environmental Protection. This work is funded by the US Department of Interior, Fish and Wildlife Service, the National Fish and Wildlife Foundation and the Willliam Penn Foundation. Good work all!

Delaware Bay Shell-a-Bration Captured on Video

Posted on May 27, 2015 by CWF

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.

Learn more about the project and our “Shell-a-Bration” event in the video above produced by Kathleen Poliski of K. Productions, LLC!

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.

Pondering the Plovers

Posted on May 26, 2015 by CWF

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!
