Netting for Golden-winged Warblers in New Jersey

GETTING A CLOSE-UP LOOK AT A BEAUTIFUL BUT ENDANGERED SONGBIRD

by Kathleen Wadiak, CWF Intern

Interning for CWF allows me to take part in a variety of projects and learn from different professionals working throughout the state. One example of this is the morning I was able to learn about golden-winged warblers through a mist netting survey. Honestly, I did not know much about this little bird until we were driving to a power line right-of-way early one morning, and I was given a quick summary of why it’s causing a stir in our home state.

The golden-winged warbler (Vermivora chrysoptera) is a striking little gray bird with black eye and throat markings, sporting a bright yellow head with matching wing patches. New Jersey serves as part of its breeding grounds throughout the summer, when it migrates north from its winter habitat in Central and South America. Unfortunately, its populations have been in decline, resulting in its classification as a state endangered species.

There are a few possible reasons for the decline in golden-winged warbler populations, including a decrease in their habitat, early-successional sites which consist of shrubby and herbaceous ground cover instead of mature forest. To the golden-winged warbler’s disadvantage, much of its New Jersey forest was cut at the same time, resulting in even-aged stands that are now too old to provide the nesting sites necessary for survival. Currently, golden-winged warblers occupy regenerating clear cuts, wetlands, or utility right-of-ways in northwestern New Jersey, where they can still find the resources that they need.

In addition to habitat loss, interactions with the closely related blue-winged warbler (Vermivora cyanoptera) are impacting the golden-wings’ numbers. It is thought that as climate change causes shifts in the geographic range of both species, more overlap between the two occurs. This results in increased competition for food, nesting sites, and even mates, as the two birds are closely related.

Walking through the high grass under the powerlines, we stopped now and then to listen to birds singing and look for golden-wings. While my untrained ears had trouble differentiating between all of the different calls, a biologist with NJ Audubon confidently told us where to begin setting up each net. After the net was raised, different recordings meant to attract the warblers played while we stepped back and waited hopefully for the right birds to come.

It was exciting to see the first birds fly into the net and to have the opportunity to view them up close, even if they weren’t always the ones we were looking for. While we set up three nets throughout the morning, our first attempt was most successful as it resulted in the capture of one of the rare golden-winged warblers! Its banded leg told us that this wasn’t its first time in a net, and that it had been to this site in the past, a good sign for this particular stretch of habitat. Its dramatic markings and flashes of gold feathers made it a beautiful bird, and it struck me what a shame it would be if they disappeared completely from our state.

While things are tough for golden-winged warblers in New Jersey, hope is not lost as many organizations, including CWF, the Natural Resources Conservation Service, NJ Audubon, and NJ Division of Fish and Wildlife are working to keep these birds in the Garden State. Mist netting and banding the Golden-wings allow biologists to track the number and location of these warblers throughout their breeding grounds and aid in the creation of management strategy. In addition, there is an effort to educate private landowners about golden-wings and to help them manage their property in a way that attracts the birds. Hopefully, as this work continues, more land will be suited to their habitat preferences, and golden-winged warblers will return to their summer homes in New Jersey.

Diamondback Terrapins off Game List

UNDER-SERVED SPECIES RECEIVES RECOGNITION IN NEW JERSEY

by Corrine Henn, Assistant Communications Manager

Last week on July 15th, Governor Chris Christie signed a bill into law effectively making it illegal to hunt or harvest diamond terrapin, a species native to New Jersey’s coastal salt marshes. Now legally considered a non-game indigenous species, the terrapin will be subject to all laws and regulations as stated in the Endangered and Nongame Species Conservation Act.

 

DSC_6820_crop

 

For many, this news is long time coming. Since 2009, Conserve Wildlife Foundation of New Jersey has worked diligently alongside our partners to conserve, research and raise awareness for the plight of the diamond terrapin. The Great Bay Terrapin Project aims to reduce the number of deaths and simultaneously educated the public on the importance of conserving this vital species.

 

Out of all the threats the terrapin face, including habitat loss, ghost crab traps, and accidental deaths, harvesting of the terrapin has increased in a number of areas around the state as the demand for terrapin (as pets) and terrapin meat grows in overseas markets.

 

Up until this new legislation, the diamondback terrapin could be legally harvested in New Jersey during the permitted hunting season. Unfortunately, there has never been any formal regulation in place to keep track of just how many were being taken from the wild. All that was required was that the terrapin be caught by hand. However, an incident in 2014 that resulted in the harvesting of near 3,500 terrapins only reaffirmed that something more needed to be done.

For the past two years, the New Jersey Department of Environmental Protection (NJDEP) commissioner Bob Martin signed an administrative order ending the harvesting season early. The culmination of these incidents, along with years of monitoring and studying the terrapin and the ongoing threats they face supported the concerns brought forward in the legislation to Governor Chris Christie.

 

We have never been able to fully grasp the status of the terrapin population here in New Jersey, but this legislation opens up new opportunities and renewed hope, to those of us not only at CWF but our partners around the state. We hope that this new law will deter those who wish to harvest the terrapin illegally, and that those who do and are caught will be prosecuted.

 

In the meantime, there are still many ways you can help in protecting this beautiful and unique species.

Beachnester Buzz: Post-nesting Season Migration Begins

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 Jersey’s Hidden Coast – Strengthening Bayshore Beaches

NEW JERSEY’S HIDDEN COAST – EPISODE 5

By Emily Hofmann, Assistant Communications Manager

 

Like all ecosystems, Delaware Bay is amazingly complex, and there’s no one way to fix it. Between climate change, sea level rise, and the growing risk of major storms, there’s a lot to consider.

 

We’ve learned that restoring healthy marsh habitat is a key component in rebuilding Delaware Bay beaches; however, we’re also trying to further strengthen bayshore beaches by building reefs – living underwater infrastructure. By creating some reef structures we can keep the sand where we’re putting it.

 

Learn more about strengthening New Jersey’s Hidden Coast – the Delaware Bayshore in our fifth episode to our 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.

Beachnester Buzz: Meet Bob, Avalon’s “Famed” Piping Plover

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

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.

The Inspiring Story of Osprey 39/D

A promising outcome from a dangerous situation

by Ben Wurst, Habitat Program Manager

Yesterday evening, while conducting an osprey nest survey at Sedge Island Wildlife Management Area, I received a message from a local wildlife photographer about an osprey nestling that was entangled. I talked to the photographer, Rich Nicol and got detailed information about the situation, the nest, and started to formulate a plan to address the situation. After learning that the nest was on a 35-40’ high pole, I knew that I wouldn’t be able to get up there without some help. Yes – a large ladder would suffice, but it would be tricky to handle the situation (with the bird being entangled). You see, after seeing photos of the young osprey, I knew it was RTF (Ready To Fly). Ospreys fledge or take their first flight at around 7-8 weeks of age. The entangled osprey was around 7 weeks old. I knew we had to act quickly to catch the bird and untangle it before it tried to fledge. This morning I saw the photos that Rich took and it clearly showed that the young osprey had monofilament or a net around its neck… Continue reading “The Inspiring Story of Osprey 39/D”

Project RedBand Alumni Update!

Osprey 44/C re-sighted at Island Beach State Park!

Project RedBand Osprey 44/C was re-sighted by Shayna Marchese on Island Beach State Park on July 3, 2016.
Project RedBand Osprey 44/C was re-sighted by Shayna Marchese on Island Beach State Park on July 3, 2016.

Really exciting news. For the first time this year, a (live and well) red banded osprey was re-sighted! 44/C was banded as a nestling on July 12, 2014 and photographed by Shayna Marchese on July 3, 2016 at Island Beach State Park. Young ospreys spend two years on their wintering grounds before returning to their natal areas. This is the first year that 44/C has returned to New Jersey. 44/C appears to be a male, and males have a higher level of site fidelity than females do, so they are more likely to return to the same area that they originated from. We aren’t surprised that one of our first red banded birds to be re-sighted in New Jersey was at Island Beach State Park, just outside Sedge Island Wildlife Management Area. For anyone who is not familiar with Sedge, it is the state’s most densely populated osprey colony in New Jersey. Around 30 pairs of ospreys nest at Sedge which is less than 3 square miles.

Healthy Marshes, Healthy Beaches

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.

Wildlife and Conservation in Honduras

A Traveling Biologist’s Favorite Honduran Wildlife Species

by Kelly Triece, Wildlife Biologist

As a final chapter to the Honduras blog series, I will be sharing with you some of my favorite wildlife experiences from the trip as a traveling biologist. The country of Honduras has a very diverse landscape including tropical forests, dry deserts, the Caribbean Sea and the Atlantic Ocean. Luckily, during our trip we were able to travel to all of these locations and that meant we were in a new location almost every night! Our accommodations varied from rustic to very rustic. Hot water was often in short supply, but hot meals and hot coffee were always on the menu and wildlife was plentiful. Honduras is a country of much scenic beauty and many local lodges and accommodations are beginning to attract tourists and travelers from across the world.

One lodge that we visited has over 100 hummingbird feeders! Hummingbirds travel from around the tropical forest to taste the sweet water and are welcomed by many eager photographers and nature lovers. Honduras has one endemic hummingbird, the Honduran emerald (Amazilia luciae), known only to a few special locations in the country. The Honduran emerald lives in dry scrub habitats of open, arid deciduous thorn forests. The species is declining due to loss of habitat from cattle grazing and development. However, local conservationists including the Honduran Corporation for Forestry Development (COHDEFOR) – a forestry agency, private landowners and non-profits are attempting to work with ranchers to preserve patches of thorn forest amongst pasture land. Through the integration and communication of conservationists and land users (ranchers), conservation has the potential to bring positive results for all end-users. If the Honduran emerald can survive on a mixture of scrub and pasture, then we may have a true success story.

 

While traveling through these various landscapes and working with the local Hondurans who are looking to bring community and wildlife together we were able to see some other great wildlife include leaf-nosed bats and boa constrictors! This boa constrictor (Boa constrictor) was found in a tree near a Neotropic cormorant (Phalacrocorax brasilianus) rookery. This boa likely feeds on the cormorants living nearby. Boas can reach up to 13 feet long and feed mostly on mammals and birds. Truly a sight to see!

We also discovered Leaf-nosed bats, tucked in palm leaves in the pine forest. Leaf-nosed bats are found throughout central and south America. Leaf-nosed bats are among the most diverse family of bats in the world and vary in diet, ranging from insects to fruits. The bats pictured here are tent-making bats (Uroderma bilobatum) that make shelters out of palm leaves. These bats are frugivores, but may also eat insects, pollen and nectar. The bats make the tent shelters by biting the mid-section of the leaf to create a V-shape. After the lead dries up, a new shelter must be made. The palm leaves provide shelter from heavy rains, sun and wind. This adaptation allows bat to travel to new locations in search of ripe fruit and to escape predators.

Throughout the trip our group had the opportunity to meet with many local leaders in conservation as well as golden-winged warbler researchers. It is clear that a multi-faceted approach to conservation is necessary in order allow for education, passion and protection to the many landscapes and wildlife of Honduras. It is through a partnership with educators, researchers, professionals, farmers, children and all locals alike that we can work to help promote the beauty of Honduras while preserving its beautiful landscapes and wildlife. These far-reach effects can be seen not just in Honduras, but in North America as well, as many of these species call both North and Central America home.

American Toad: Myths and Misconceptions

Learn the Facts about a Common New Jersey Amphibian

by Liam Hobbie, Field Intern

Adult American toad photo by Kelly Triece

Did you know that wetlands are very important habitats that provide benefits for both humans and wildlife alike? Generally defined as “land consisting of marshes or swamps”, wetlands provide natural flood control by soaking up runoff from heavy rains and filter out chemicals, pollutants, and sediments that would otherwise contaminate our drinking water. They also provide a home for much of the fish and wildlife species that inhabit the state of New Jersey.

 

Due to the extensive development and urbanization of the state to accommodate our ever-growing population, much of New Jersey’s natural wetlands have ceased to exist. In the 1980’s a study conducted by the United States Fish and Wildlife Service (USFWS) found that, since the mid-1900’s, the state lost at least 20 percent of its natural wetland resources. Since then, concerted efforts have been made to protect, restore, and create wetland habitats across the state. One such effort has been made by the Natural Resource Conservation Service (NRCS) with the Wetland Reserve Easement (WRE) project, a component of The Agricultural Conservation Program in partnership with Conserve Wildlife Foundation. WRE is a voluntary program that provides an opportunity for landowners to receive financial assistance in exchange for permanently protecting retired agricultural land.

While walking one such easement property in Bedminster, Somerset County we observed a population of American Toad (Anaxyrus americanus) polliwogs in a shallow water inlet along the Lamington River. There had to be hundreds of these young toads both in the water and on the shore. The American toad is just one example of a wildlife species that benefits from readily available wetland habitat and that is also vulnerable to habitat loss due to wetland destruction. Although they are very common in New Jersey, and many people can recognize a toad when they see one, there are still a handful of myths and misconceptions about toads that I would like to address.

American toad- just metamorphizing into an adult! Photo by Kelly Triece

Myth 1 – Toads will give you warts if you touch them: False. While toads do have warts across their bodies, they cannot transmit these warts to humans as warts in people are actually caused by a virus. This doesn’t mean you should go around handling every toad you come across, but if you do pick one up you will not contract warts from it.

 

Myth 2 – Toads must be completely safe to handle if they do not transmit warts: False. Toads secrete toxins through their skin so it is completely necessary to wash one’s hands after handling a toad. They also are known to pee in self-defense, especially when picked up by a human. This may not bother some people but you should still make sure to wash your hands after holding one.

 

Myth 3 – Wild-caught toads make good pets: False. While toads are very easy to care for, and it is not hard to replicate their natural environment in a fish tank, it is still very important to leave wild toads wherever you find them. Toads will spend their whole lives in one area, leaving it once or twice a year just to go breed, and it can be very disruptive to a toad’s well-being to find itself in a new home. If you do happen to keep a toad for more than a few minutes, it is of utmost importance that it gets returned to exactly where you found it. Releasing it into any suitable habitat would seem adequate enough, but it would be like if one day you just found yourself wandering around Nebraska with no way of knowing where to go or how to get home!

 

Myth 4 – Toads are terrestrial species and do not need to be near water to thrive: False. Toads will spend most of their lives hanging out in fields or meadows or even forests, but they do need access to pools of water in order to breed. Every summer, toads will migrate to pools to find mates and to lay eggs. While they do not swim, like their close relative the frog, they still benefit from having shallow water habitat in close proximity to where they spend most of their time.

 

Myth 5 – Toads are poisonous: TRUE. Contact with a toad’s skin will not give you warts and it will not poison you just through skin-to-skin contact. However, they have glands just behind their eyes that when pressed will secrete a milky-white substance that can severely harm someone if ingested. This may not be a danger to most people, as most humans have no interest in putting toads in their mouths, but it is a concern for dogs. Dogs very typically love to grab strange objects with their mouths, which applies enough pressure to a toad’s glands to excrete their poison. This can be very detrimental to a canine’s health and can even kill them. If you find yourself wandering around toad habitats with your beloved pup ensure that they do not try to eat any toads that they come across. If your dog does mistakenly poison itself you should take it to a vet immediately.

Through programs like WRE, more and more wetland habitats are being made available across the state for wildlife species like toads. It is important to be aware of what impact you can have on them, as well as what could happen to you or your pet through contact with toads.
