In New Jersey, catching a glimpse of an American kestrel is a rare treat! These beautiful, colorful birds of prey are about the size of a mourning dove — they are the smallest falcon in North America. Kestrels are one of two falcon species that nest in New Jersey.

 

American kestrels are opportunistic hunters, feeding on a number of different animals like grasshoppers, lizards, mice, snakes and small birds. Unlike peregrine falcons, kestrels don’t use speed to kill their prey. They perch to see their target and then use a stationary, hovering flight that allows them to dive down short distances to capture their prey. The eyespots of a kestrel make it appear to be “looking” up at its aerial predators, like Cooper’s hawks, causing the predators to move on to find a less “alert-looking” target. The eyespots give kestrels the opportunity to focus on hunting for prey beneath them.

 

Kestrels also hide surplus prey in grass clumps, tree roots, bushes, fence posts, tree limbs, and cavities, to save the food for lean times or to hide it from potential thieves!

 

Kestrels utilize these hunting tactics in open, grassy habitats — especially ones with cavities for nesting and perches for hunting. Kestrels can be seen hovering in grasslands, pastures and parklands or perched along the road on telephone lines.

 

KestrelRangeKestrels can be found in both North and South America, from Alaska and Canada in the north to Argentina in the south. During winter in North America, they will migrate southward from the northernmost portion of their range. They live year-round within New Jersey.

 

Although the American kestrel is widespread, meaning they live year round throughout much of the United States, the northeastern kestrel population is declining. Today, the kestrel is listed as a threatened species in New Jersey.

 

The decline of kestrels in New Jersey is likely due to destruction of grasslands from development. Nesting cavities are also being lost. As humans clean up fields, we remove trees with nest cavities that kestrels use. Kestrels are secondary cavity nesters. They don’t make their own cavity but use existing natural or man-made cavities.

 

Since kestrels nest in buildings and other man-made structures, nest box programs are an effective way to help grow the number of kestrels in areas where nest sites are limited.

 

Conserve Wildlife Foundation of New Jersey, in partnership with the Endangered and Nongame Species Program implemented a nest box installation and monitoring program in 2006. Nest boxes have been placed in areas of habitat determined to be suitable for the birds of prey. The boxes are monitored by biologists during the breeding season. Because kestrels reuse nest sites, particularly if they have successfully raised young, we focus on boxes that have been successful at least once since 2006.

 

The nest box program in New Jersey appears to be successful; we are adding to the population. Since 2006, we have banded over 300 fledglings. You can help too! Next time you see an American kestrel in the Garden State, be sure to submit a Rare Species Sighting form.

International Migratory Bird Series: Great Blue Heron

CWF is celebrating International Migratory Bird Day all Week Long

by Lindsay McNamara, Communications Manager
CWF’s blog on the great blue heron is the fourth 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.

Have you seen a great blue heron wading in the marshes of the Garden State? While they are commonly seen along shorelines, river banks, and the edges of marshes, estuaries, and ponds, the breeding population of these wading birds is actually listed as a Species of Special Concern in New Jersey.

 

The term ‘Species of Special Concern’ applies to wildlife species that warrant special attention because of some evidence of decline, inherent vulnerability to environmental deterioration, or habitat modification that would result in their becoming a Threatened species.

Due to its wide distribution, varied diet, and flexibility in nesting near both freshwater and saltwater environments, the great blue heron’s population in North America is stable. However, wetland destruction in New Jersey has caused a decrease in heron populations from their historic numbers. Since the 1950s, habitat loss has occurred at an alarming rate in New Jersey, destroying wetlands critical to breeding herons.

 

Protecting our wetland habitats from disturbance and development will help protect the great blue heron, the largest wading bird in North America. Great blue herons are 46 inches long and have a wingspan of 72 inches. Despite their large size, great blue herons only weigh 5 to 6 pounds, in part because of their hollow bones — a feature all birds share.

 
Great blue herons can hunt during the day and night, thanks to a high percentage of rod-type photoreceptors in their eyes that improve night vision. They eat nearly anything within striking distance, including fish, amphibians, reptiles, small mammals, insects, and other birds. Herons nest in colonies or “rookeries” in tall trees near bodies of water.

 

The oldest great blue heron on record was found in Texas when it was at least 24 years, 6 months old!

 

RangeMapThe great blue heron occurs throughout most of North America, from Alaska and eastern Canada in the north to the northern portion of South America in the south. Northern populations of great blue herons east of the Rockies are migratory.

 

They withdraw from the northernmost portion of their range during the winter, some traveling to the Caribbean, Central America or northern South America. This species breeds throughout New Jersey. They generally do not occur within the northwestern corner of the Garden State during winter. Great blue herons migrate singularly or in small flocks, mainly in daytime.

 

We still have much to learn about the biology and population status of great blue herons in New Jersey. Research needs to be conducted to find additional breeding sites, check existing nesting areas, and determine whether the population might be decreasing or increasing. You can help! Next time you see a great blue heron in the Garden State, be sure to submit a Rare Species Sighting form.

International Migratory Bird Day Series: Red Knot

CWF is Celebrating International Migratory Bird Day all Week Long

by Lindsay McNamara, Communications Manager

CWF’s blog on the red knot is the third 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 iconic red knots have returned to New Jersey! These famous, mid-sized shorebirds are state endangered and now federally threatened — the first bird ever listed under the Endangered Species Act with climate change cited as a “primary threat.”

 

Red knots are only 10 inches long but are among the world’s most extreme long distance flyers  traveling vast distances  some over 18,000 miles in the course of their annual migration from Tierra del Fuego, Argentina all the way up to the Canadian Arctic (and back again). During their trip, the red knots make a vital stop at New Jersey’s Delaware Bay.

This map shows the flight path of a red knot that was banded and fitted with a geolocator along New Jersey's Delaware Bay.
This map shows the flight path of a red knot that was banded and fitted with a geolocator along New Jersey’s Delaware Bay.

Each spring in Delaware Bay, throughout the month of May, the largest concentration of horseshoe crabs in the world comes onshore to spawn. At the same time, tens of thousands of shorebirds arrive at the Bay, thin and spent from what has been a non-stop, four-day flight from South America. They are en route on a remarkable round-trip journey from southern wintering grounds to Arctic breeding territory, and Delaware Bay is their most critical stopover on this 8,000-mile trip. The shorebirds need to quickly double their weight to complete their migration north and breed successfully. To refuel at such capacities and in only a ten-day window, high-energy horseshoe crab eggs provide essential nourishment. In recent years, countless horseshoe crab eggs have been lost because of the devastating storms that swept away the beaches they depend on.

 

In the wake of Hurricane Sandy, Conserve Wildlife Foundation and American Littoral Society 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 over 85,000 cubic yards of sand and restored seven beaches along New Jersey’s Delaware Bayshore.

 

To restore one of the beaches, Thompsons Beach, our team removed debris from the area, removed rubble from the road leading to the beach, and placed over 40,000 cubic yards of sand onto the beach. We were delighted to learn that in the spring of 2015, Thompsons Beach had the highest abundance of horseshoe crab egg clusters out of all the beaches that our team monitors on Delaware Bay.

But since the early 1990s, there have been major declines in both the number of adult horseshoe crabs and their eggs. The cause is an exploding crab harvest that grew from only tens of thousands in 1990 to over 2 million in 1996. With the decline of their critical food source, shorebird numbers also plummeted  the Delaware Bay shorebird populations remain around 26% of its historic population size. Over 25,500 red knots were seen in 2015 versus over 90,000 in 1989.

 

Conserve Wildlife Foundation and the Endangered and Nongame Species Program (ENSP) of the New Jersey Department of Environmental Protection’s Division of Fish & Wildlife have partnered for 20 years, working to conduct research on Delaware Bay shorebirds in order to prevent further decline. Each year, CWF’s Larry Niles and ENSP’s Amanda Dey lead a team of shorebird experts from around the world – from countries as far as Argentina and New Zealand – to conduct research on shorebirds during their stopover. These experts also follow shorebirds to other locations along their migration, including South America and the Arctic. With scientific research and concerted conservation efforts, our hopes are that someday Delaware Bay’s skies will be once again filled with shorebirds.

Last year, nearly every red knot left the bay in good condition, with over 77% reaching weights exceeding 180 grams, the threshold weight required for a successful flight to the Arctic breeding areas. The improvement in the number of red knots reaching 180 grams is a milestone for our shorebird project. The birds left in the best condition recorded since 1998, just as horseshoe crabs were being overharvested. This good news must be tempered by the continued low numbers of birds and horseshoe crabs. We report no improvement in horseshoe crab numbers, so the improvement in the number of red knots making weight is likely a consequence of the restoration of horseshoe crab habitat on Delaware Bay beaches.

 

Because shorebirds don’t only spend their time in Delaware Bay, shorebird scientists must study them throughout the Atlantic Flyway to get the best understanding of their unique ecology. This year, shorebird project team was awarded a 2-year grant to create detailed shorebird habitat maps in the states of Maranhão and Pará, Brazil. This project will set the foundation for conservation planning and action for decades to come at a shorebird wintering site of hemispheric importance that has received little conservation and research attention with regard to shorebirds thus far.

 

Over the last 6 years, CWF also has partnered with the USFWS Monomoy Refuge to develop a better understanding of migratory shorebird use on Cape Cod and at the Refuge. Cape Cod, like Stone Harbor and Brigantine, New Jersey, is an important southbound stopover for red knots. At each location, red knots come from their Arctic breeding areas and either build up weight for a flight to South America, or remain to molt and replace vital primary feathers before moving onto shorter distance wintering areas in Florida and Cuba.

Another important piece of CWF’s shorebird research has been the attachment and recovery of geolocators, small devices that track movements through one to two years of battery life. The migratory tracks from recovered geolocators have greatly expanded our understanding of red knot migratory behavior. In CWF’s last two years of research, we focused on capturing juveniles, which move through the Cape in early September. Red knot juvenile #254 was a recapture two years after release on Delaware Bay. It first left Cape Cod and wintered in North Carolina. In their first year, juvenile red knots don’t go to the Arctic to breed and so #254 flew back to Cape Cod to summer. The following fall, it flew to Cuba to winter, then to North Carolina, then to the Arctic. This was the first known track of a juvenile red knot and one of only a few of any avian species! CWF is continuing our geolocator project this year, so follow along on our blog and social media channels to receive updates on cutting-edge red knot research!

International Migratory Bird Day Series: Piping Plover

CWF is Celebrating International Migratory Bird Day all Week Long

by Lindsay McNamara, Communications Manager

CWF’s blog on the piping plover is the second 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 piping plover – a small sand-colored shorebird that nests in New Jersey as part of its Atlantic Coast range from North Carolina up to Eastern Canada –weighs only one to two ounces and is about six to six and a half inches long. These tiny shorebirds migrate all the way to their wintering grounds along the coast of eastern Mexico and on Caribbean islands from Barbados to Cuba and the Bahamas.

 

Migrants can be seen in New Jersey from early March to late April and again from mid-July to the end of October. Females are the first to leave the breeding grounds, followed by males, then juveniles. Breeding plover “hot spots” in each coastal county of New Jersey are Gateway National Recreation Area – Sandy Hook Unit, Barnegat Light, North Brigantine Natural Area and Stone Harbor Point.

 

We see a number of migratory piping plovers in New Jersey because the Garden State is roughly in the middle of their breeding range. Todd Pover, CWF’s beach nesting bird project manager, reasons that we have a high number of Eastern/Atlantic Coast Canadian breeders that stop in New Jersey — based on band resights — albeit usually for just a day on their way north to breeding grounds. Therefore, New Jersey may play an important role in the piping plover life cycle not just for breeding, but for migration as well, which emphasizes the importance of protecting shorebirds in all phase of their lives or “full life-cycle conservation”.

 

Piping plovers face a number of threats, including intensive human recreational activity on beaches where they nest, high density of predators, and a shortage of highly suitable habitat due to development of barrier islands and extreme habitat alteration.  Sea level rise and increased storm activity related to climate change will also likely lead to more flooding of nests.

 

Federally listed as a threatened species in 1986, piping plovers have since recovered in some areas of the breeding range. Yet piping plovers continue to struggle in New Jersey, where they are listed by the state as endangered. For more information about piping plover nesting results in New Jersey, please read Conserve Wildlife Foundation’s 2015 report.

CWF, in close coordination with NJDFW’s Endangered and Nongame Species Program, oversees piping plover conservation throughout New Jersey. Staff and volunteers help erect fence and signage to protect nesting sites, monitor breeding pairs frequently throughout the entire nesting season from March to August, and work with public and municipalities to educate them on ways to minimize impacts. Although conservation efforts on the breeding ground remain the primary focus, in recent years, CWF has also begun to work with partners all along the flyway, in particular on the winter grounds in the Bahamas, to better protect the at-risk species during its entire life-cycle.

 

We are working hard to link students across the piping plover’s flyway through our Shorebird Sister School Network, where we pair up schools in New Jersey and the Bahamas, one of the most important wintering areas for Atlantic Coast piping plovers. Now, we are hopefully recruiting some Canadian students as well.

 

Conserve Wildlife Foundation will continue to find innovative ways to save the small migratory shorebird. In 2015, 108 pairs of piping plovers nested in New Jersey, a 17% increase from 2014. What will 2016 bring? Follow us on social media to learn more about the tireless efforts of a team of passionate, dedicated biologists working to save the iconic coastal species.

International Migratory Bird Day Series: Golden-Winged Warbler

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 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.

Exploration of An Ecosystem That Most People Will Never See

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

by Lindsay McNamara, Communications Manager

AndreaProctor_SpringPeeper

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:

395 Abandoned Crab Pots Removed from Barnegat Bay Estuary

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

by Lindsay McNamara, Communications Manager

A pile of abandoned crab pots before being processed at the WeCrab community day.

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
Abandoned crab pots recovered by Stockton University.

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 23rd 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 ScienceMonmouth UniversityStockton UniversityReClam 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.

Connecting the Life Cycle of a Golden-winged Warbler

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

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!
