CWF is celebrating International Migratory Bird Day all week long

by Kelly Triece, Private Lands Biologist

Kelly Triece’s blog on the Golden-winged Warbler is the first in a series of five to be posted this week in celebration of International Migratory Bird Day (IMBD). IMBD 2016 is Saturday, May 14. This #birdyear, we are honoring 100 years of the Migratory Bird Treaty. This landmark treat has protected nearly all migratory bird species in the U.S. and Canada for the last century. 

 

The Golden-winged Warbler (GWWA), Vermivora chrysoptera, is a Nearctic-Neotropical Migrant songbird that spends half its life in Central or South America and the other half in North America. This small songbird is less than 5 inches long with a slim body and short tail. GWWA are most noted by their yellow-patched wings, yellow cap and black-and-white face.

 

Right now, GWWAs are migrating to their breeding habitat in North America. They return every spring to the Upper Mid-west and Appalachians, including New Jersey, where they find a mate, breed and rear their young. The breeding range of the Golden-winged Warbler extends along the Appalachians from the northern portion of Georgia in the south to Vermont in the north.

 

Our latest report from the online observation database, eBird, reported a Golden-winged Warbler sighting in Cameron County, Texas on May 3! They are currently migrating north, and do so mostly at night. GWWA migrate at night to avoid predation from day-time predators such as American crows or Blue jays. The skies are also friendlier at night with less turbulence, allowing the birds to stay the course more readily. In addition, migrating birds need to forage to maintain energy during the long migration and must do so during the day. So flying at night gives the bird’s ample time to chow down! Get ready New Jersey!

In September, after breeding season, Golden-winged Warblers migrate south, mainly through a corridor of states east of the Mississippi River and west of the Appalachians. The winter range for this species is southern Mexico and Central and South America, including Colombia and Venezuela. Migrants are seen most commonly in late April and May, and during September.

 

Recent studies have shown that Golden-winged Warblers can also migrate in response to storm events (Streby et al. 2015). While GWWAs migrate long distances twice a year to occupy their breeding and wintering habitat, they may also “mini-migrate” to avoid large storm systems. Last year, a study in Tennessee found that Golden-winged Warblers evacuated their breeding territories days before a large storm system. After the system they returned to their breeding grounds and continued to defend their territories and breed. This research is important as it may provide future insight into the energetic demands and fitness consequences of these “mini-migrations.” As climate change continues to increase the frequency and severity of large storms along the east coast the “mini-migrations” may impact the overall fitness of the species as the energetic demands of migrations are great (Streby et al. 2015).

 

Golden-winged warblers are threatened due to habitat loss in their breeding range and wintering range. Golden-winged warblers require early successional, young forest habitat to nest and raise their young. Young forest habitat, also known as scrub-shrub habitat, is new or regenerating forest that is less than 20 years old.  In its breeding range in North America, habitat loss has occurred as forests have matured. In the past 30 years, over 11,000 acres of upland shrub and emergent wetland habitat have been lost to succession in New Jersey. In a naturally occurring system, where fire, wind, flooding and other disturbances are not controlled by humans this age class would be more evenly distributed. In addition, loss of quality stopover and wintering habitat may also be contributing to declines. Golden-winged warblers are a federal species of concern and endangered in the state of New Jersey. Through management and proper forestry techniques, more diversity can be created to balance the age of the forest. This type of forestry management can help protect the Golden-winged warbler in its breeding range.

The Birds are Back – Red Knots Arrive Along the Bayshore

by David Wheeler, Executive Director

The 2016 mass shorebird migration is officially underway, with the thrilling spectacle of over 1,100 red knots spotted today at North Reeds Beach in Cape May County, New Jersey. A host of other shorebirds, including ruddy turnstones, dunlins, semipalmated sandpipers, and sanderlings, accompanied the red knots at this Delaware Bay hotspot.

 

The famished flocks fed on horseshoe crab eggs, while much larger laughing gulls congregated along the shoreline and a few crabs used the incoming waves to flip themselves over and return to the bay.

Researchers began seeing a large number of shorebirds arriving over the weekend, and today’s sightings are high for such an early date. A number of the red knots wear leg bands, with a few indicating departure points as far south as Argentina and Chile. Such lengthy migrations for those individual birds only add to the intrigue of their early-season arrivals in New Jersey.

 

Some red knots fly over 18,000 miles each year in their migrations from southern South America to the Canadian Arctic, with Delaware Bay serving as an irreplaceable stopover.

Yet these migratory shorebirds have suffered a sharp decline over the past few decades, with red knots dropping by around 75%. The U.S. Fish and Wildlife Service designated the red knot as a federally protected threatened species under the Endangered Species Act in December 2014.

 

A team of international researchers and trained volunteers, led by Dr. Larry Niles, Conserve Wildlife Foundation, and the State Endangered and Nongame Species Program will spend the next month surveying and studying the at-risk shorebirds during their stay in New Jersey.

CWF Vernal Pool Walks Connect New Jersey Residents with Rare, Seasonal Marvel

by Lindsay McNamara, Communications Manager

We all know that “April showers bring May flowers,” but the earlier rains of March stir up beauties of a different kind. When the first spring raindrops hit the barely-thawed ground and night falls on the forest, frogs, salamanders, and toads emerge from their winter burrows. These amphibians – the spotted salamanders, wood frogs, spring peepers, and others – are anxious to get to their breeding pools and lay their eggs. The waters that they choose are called vernal pools because they fill with rainwater, snowmelt, and rising groundwater in early spring but then dry up as summer advances. The pools are thus temporary and cannot support fish, meaning fewer predators for the amphibian eggs and young.

In the northeastern United States, vernal pools are home to over 500 species. In New Jersey, these pools are critical habitat for amphibians, reptiles, invertebrates, migratory waterfowl, raptors, and songbirds. All 14 of New Jersey’s frog species use vernal pools to breed and two endangered salamander species breed exclusively in vernal pools, including Cape May’s eastern tiger salamander.

The new generation of amphibians must race to complete metamorphosis and leave the vernal pool before the water does. Under perfect conditions of warm, thawing, nighttime rains, there may be hundreds or even thousands of amphibians moving at once toward the same breeding pool. The darkness and the rain allow them to move stealthily over the landscape, hidden from predators like the owl and raccoon.

 

CWF’s Kelly Triece organized a series of walks through the vernal pools of Waterloo Village in Sussex County, New Jersey, and showed residents the unexpected creatures swimming in the pool’s shallow waters. Kelly led the exploration of an ecosystem that most people will never see! Participants listened to the songs of Spring Peepers and discovered salamander eggs, fairy shrimp, and other unique creatures as the evenings set in. Here are photos from her walks:

CWF Spearheading Project to Recycle Dangerous Fishing Gear and Create Healthier Bay Ecosystem and Local Economy

by Lindsay McNamara, Communications Manager

Through a series of public and private partnerships, and with the help of the local fishing community, CWF is leading a project to inventory and remove more than 1,000 abandoned crab pots in Barnegat Bay. These derelict pots, lost from storms or cut lines, can have devastating impacts on the bay ecosystem and local economy.

 

A phenomenon referred to as “ghost fishing,” these traps will often continue to catch and kill marine life when abandoned, like the Northern diamondback terrapin and otherwise harvestable crabs. These lost harvests translate to economic losses for fishermen and the local community. The pots also disrupt navigation and damage sensitive ecosystems.

 

In the first year of our two year project, our partners removed 395 of these abandoned crab pots from the Barnegat Bay watershed, championed by local fisherman RJ Cericola and his crew. Almost 260 other pots were assessed but not recovered.

• RJ Cericola: 204 abandoned crab pots removed
• MATES: 103 abandoned crab pots removed
• Stockton University: 64 abandoned crab pots removed (40 near Waretown and 24 near Mud Cove, Little Egg Harbor Bay, reflected in the map below)
• Monmouth University: 24 abandoned crab pots removed

Starting in December 2016, we look forward to working with RJ Cericola, our new partner Jeff Silady — ReClam the Bay boat captain and local fisherman — and bringing on a commercial fisherman to reach our goal of 1,000 abandoned crab pots recovered.

 

Some of the recovered pots were stored at Stockton University Marine Field Station in Port Republic and were inventoried for data; broken down and recycled by volunteers this past Earth Day.

Scientists, students, commercial crabbers and other volunteers gathered on April 23^rd for the WeCrab Community Day to record data, clean and prep the recovered derelict crab pots for recycling. The WeCrab Marine Debris Project is a partnership between the Jacques Cousteau National Estuarine Research Reserve and Stockton University.

 

Volunteers collected data on condition, cause of loss, weight, among other points. We are working to understand the impacts of abandoned pots and their distribution, gather information on the percentage of pots lost annually and also develop a long-term reporting system for lost pots and other fishing gear. Information collected from recovered pots help aid these efforts.

 

CWF’s abandoned crab pot removal project is funded by NOAA’s Community-based Marine Debris Removal Grant. We are proud to work with our partners at the Marine Academy of Technology and Environmental Science, Monmouth University, Stockton University, ReClam the Bay, and volunteers. Conserve Wildlife Foundation is also working on an outreach campaign to raise awareness on the impacts of derelict crab pots and marine debris with additional funding from the New Jersey Corporate Wetlands Restoration Partnership.

A Closer Look at Cutting-Edge Research on the Multi-Country, Migratory Life-Cycle of GWWA

by Kelly Triece, Private Lands Biologist

While in Honduras this February 2016, I had the opportunity to meet researchers studying the Golden-winged Warbler (GWWA) in their wintering habitat. The GWWA is Neotropical Migrant songbird that breeds in New Jersey, but migrates south for the winter. Golden-winged Warblers migrate south in September, mainly through a corridor of states east of the Mississippi River and west of the Appalachians. Their peak return migration to the Upper Mid-west and Appalachians, including New Jersey, occurs in late April where they find a mate, breed and rear their young.

 

This neo-tropical songbird is a species of special conservation concern in the U.S. and endangered in New Jersey, experiencing population declines due to loss of young forest habitat on their breeding grounds, habitat loss on their wintering grounds and hybridization with the Blue-winged Warbler (BWWA). The GWWA has experienced one of the steepest population declines of any songbird species in North America. The population size of the GWWA has decreased by an average of 2.6% every year, according to the USGS Breeding Bird Survey, since the survey began in 1966.  In particular, the Appalachian populations are now approaching a rate of -9% per year. Due to the difficulty of tracking birds over large distances, the effects of their multi-country, migratory life-cycle are poorly understood.

 

While many songbirds, migrate thousands of miles every winter, most research has focused on their breeding habitat in North America. Recently, researchers have begun exploring and understanding the importance of conserving the entire life-cycle of migratory birds or any wildlife species. Ruth Bennett, a Ph.D student at Cornell University is one such scientist. Ruth and collaborators at the American Bird Conservancy and Indiana University of Pennsylvania are linking breeding and non-breeding Golden-winged Warbler populations through geolocator technology. Ruth is also studying how changes in land use that lead to habitat loss on the wintering grounds of the GWWA are linked to population declines, with support from the US Fish and Wildlife Service Region 3.

 

Ruth Bennett, P.h.D. student, aims to connect the wintering habitat of the GWWA and its breeding habitat through her research in Central America. Between November 1, 2015 and March 15, 2016, Ruth and collaborators deployed geolocators on 145 GWWA and 35 BWWA at 9 sites from Belize through Panama, including Honduras. She will then recapture the individuals next winter, 2016-2017. These geolocators supply location data for up to 12 months, giving insight into the full life-cycle of the Golden-winged Warbler and closely-related Blue-winged warblers (BWWA). Through this research she will be able to establish the migratory pathways for all recaptured individuals. She will be able to compare how habitat loss on their wintering grounds and land use changes correlate with population trends described on the breeding grounds.

 

This will be one of the first geolocator studies to establish the connectivity of a migratory species from a winter grounds origin.  This research is important, because it creates a connection between non-profit, local and state governments in the United States and those in Latin America. This may increase funding opportunities and increase the efficiency of conservation action taken on the winter grounds. This research is especially important, as it forms one of the core informational components of the Golden-winged Warbler Non-breeding Season Conservation Plan (currently in review, soon to be available at gwwa.org). The conservation plan provides a regional strategy for conserving Golden-winged Warbler wintering habitat based on the wintering ecology of this species. The plan furthermore outlines conservation projects and budgets within high priority wintering focal areas that have been developed by Latin American partners. Ongoing research will be critical to ensure that these conservation actions effectively conserve the non-breeding habitat of this declining species.

 

Ruth has a small crew of local biologists who assist in her research in Latin America. Through her research in Honduras and Central America, Ruth has been able to connect with many local biologists and conservationists. It was great to meet Ruth in Honduras and learn about her research, which so important to New Jersey, but taking place so far away.

 

Our next Honduras blog, will feature our time with Ruth at the Feria de Aves Migratorias (Migratory Bird Festival) at the Universidad de las Agricultureal (Agriculture University) in Olancho, Honduras!

Second Annual “Shell-a-Bration” brings volunteers to strengthen coast’s resiliency and habitat

by Lindsay McNamara, Communications Manager

Today, conservation organizations leading the efforts to restore New Jersey’s Delaware Bay beaches today organized the Second Annual “Shell-a-Bration” oyster reef building volunteer event.

 

Dedicated volunteers braved the elements and worked alongside American Littoral Society and Conserve Wildlife Foundation of New Jersey to establish a near-shore whelk shell bar at Moores Beach in Maurice River Township along New Jersey’s Delaware Bayshore. The shell bar was built to prevent sand loss from wind-driven waves. An approximately 200-foot oyster reef was constructed offshore to test whether the reef bars help reduce beach erosion and create calmer water for spawning horseshoe crabs.

 

“The Second Annual Shell-a-Bration truly celebrates the ecology, community, and culture of the Delaware Bayshore,” stated Captain Al Modjeski, Habitat Restoration Program Director, American Littoral Society. “It reinforces the connectivity between the natural and human-built bayshore communities through reef building and celebrates the significance of the Bay’s resources through restoration.”

“There are many strategies to defend our Delaware Bayshore, but one of the best and most productive are these oyster reefs,” stated Dr. Larry Niles, a biologist with American Littoral Society and Conserve Wildlife Foundation of New Jersey. “They not only replicate a lost but important habitat on Delaware Bay — reefs once covered much of the bayshore — but they provide just enough protection to make a difference in how long our beaches persist against the unrelenting forces of nature. In a way, we are fighting nature with nature.”

 

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 new oyster reef will attenuate waves but still allow for horseshoe crab breeding. In existing areas where crabs can breed without interruption, like creek mouths protected by sand shoals or rock jetties, egg densities can exceed ten times the egg densities on unprotected beaches.

 

“New Jersey’s Delaware Bayshore hosts an annual wildlife spectacle of global significance – the time-honored migration of Red Knots to reach the eggs of these ancient horseshoe crabs,” said David Wheeler, Conserve Wildlife Foundation of New Jersey Executive Director. “Red Knots fly to New Jersey’s Delaware Bay from as far away as Tierra del Fuego in South America to feed on horseshoe crab eggs. Volunteer projects like the Shell-a-bration help connect the people of New Jersey with these endangered shorebirds and the largest population of horseshoe crabs in the world.”

 

Last year, over 130 volunteers and veterans built the South Reeds Beach oyster at the First Annual Shell-a-Bration. Veterans Day on the Bay 2015 dedicated the South Reeds Beach oyster reef to all veterans and highlighted veteran involvement in the effort to restore New Jersey’s Delaware Bayshore. Event attendees honored their own military veterans by inscribing that special person’s name on a shell and placing that shell on “Veterans Reef.” Guests also helped study the wildlife living in this new reef with hands-on, interactive marine science activities like seining, trapping, trawling, and species identification.

Veterans Reef and the Moores Beach Oyster Reef are two 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.

 

In the wake of Hurricane Sandy, American Littoral Society and Conserve Wildlife Foundation of New Jersey worked with the U.S. Fish and Wildlife Service, the New Jersey Division of Fish and Wildlife and the New Jersey Recovery Fund to remove 8,000 tons of debris and added 45,000 tons of sand to the beaches just before the annual spring arrival of the red knot in 2013.

 

Additional work after 2012 restored another mile of shoreline, including two new beaches of poor quality even before Sandy. To date, the groups have placed 85,000 cubic yards of sand and restored seven beaches along New Jersey’s Delaware Bayshore. In early 2016, groups began another phase of restoration work at Cook’s Beach and Kimble’s Beach in anticipation of the return of the horseshoe crabs and red knots in May.

 

The projects are being funded by National Fish and Wildlife Foundation through their Hurricane Sandy Coastal Resiliency Grants Program, and are being developed in partnership with U.S. Fish and Wildlife Service and New Jersey Division of Fish and Wildlife.

After more than a century, fishers are returning to New Jersey

by Kendall Miller, Communications Intern

 

New Jersey’s forests lost a charismatic top predator when the fisher was extirpated nearly a century ago. Exploitation of the fisher for its pelt — coupled with excessive logging practices during the 19th and 20th centuries — caused decimated populations of this North American native across its entire range. However, through the implementation of conservation practices, this small, yet spunky forest carnivore is experiencing a comeback.

 

Despite its past disappearance from the state, the combined effects of trapping bans and nearby relocation projects (New York and Pennsylvania) are resulting in the fisher’s resurgence in New Jersey. Within the last decade, the return of fishers to New Jersey has been an exciting new possibility, with multiple reported sightings, photos caught via trail camera and anecdotal stories by the public.

 

Recently, two trappings by state officials in North Jersey, both within a mere month of one another, mark the return of fishers to the state of New Jersey, and speaks for the potential future of this species, as well as others.

 

What exactly is a fisher?

Found only in North America, fishers historically inhabited forested and semi-forested land from coast to coast, ranging from Virginia to Quebec in the east. Found in deciduous, coniferous and mixed forests, they prefer areas with dense canopy cover, and tend to avoid areas with human disturbances.

 

Also referred to as the fisher cat and Appalachian black cat, this animal looks like fluffy cat meets fox, with a wolverine-like disposition. However, it is neither a feline nor does it catch fish. The fisher (Martes pennanti) is a member of the Mustelidae family, which includes otters, badgers, martens, ferrets, minks, wolverines and more.

 

The fisher is a long bodied and short legged animal, with a bushy tail that makes up a third of its total body length. There is a substantial size sexual dimorphism between males and females. Males weigh 8-13 pounds and reach lengths between 35-47 inches. Females weigh between 3 and 7 pounds and are between 30-37 inches long. Males have grizzled fur due to blonde guard hairs on their neck and shoulders, while females are a uniform chocolate brown.

 

A generalist carnivore species, a fisher will eat anything it can catch — typically small- to medium-sized mammals and birds. Carrion and some nuts and fruits also make up a portion of its diet. They are known to eliminate weak or injured deer, especially in times of heavy snow pack.

 

While its diet may be general, one part is very special: this is the only predator of porcupines in the country. The prickly defenses of the porcupine protect it against almost all predators except the fisher, who has developed a special way of hunting its prey. It will chase a porcupine up a tree until it can go no further and falls. Then, it will make a head-first descent down the tree with the help of semi-retractable claws and feet that can turn nearly 180 degrees. The fall stuns the porcupine, allowing the fisher to access the unprotected underside.

 

These predators share prey with coyotes, bobcats, foxes and even raptors, creating competition with these species. Fishers have been known to travel hundreds of miles to meet their dietary needs, able to cross water if need be.

 

They live a solitary life-style, with home ranges between 1-3 square miles, seldom overlapping, which suggests territoriality. They are found to be active at any point during the day or night. Fishers make homes in dens year round, using a variety of forest resources such as tree hollows, stumps, debris piles, natural crevices and underground tunnels. Females with litters will use tree hollows that are far off the ground.

 

Fishers themselves have no natural enemies and few disease occurrences. Trapping by humans and vehicle collisions likely account for the majority of deaths throughout their range.
