"We had a very eventful season. On top of exceeding my expectations in the amount of data collected, we managed to witness a great white shark attacking a seal off the coast of Monomoy NWR, get stranded in a hurricane with 72mph winds, see all the whales we could possibly wish for, watch a flock of over 8,000 shearwaters feeding, and make sure that EVERYONE on the team had some wonderful additions to their life-lists. I was very fortunate to have an amazing team to work with for my last field season. I met a lot of great people out on the beach, and will surely be missing Cape Cod next summer!"

Melissa's work involves patiently watching mixed flocks of staging terns at several sites around Cape Cod and recording information about their behavior and their responses to potential sources of disturbance, like people, boats, and predators. Melissa's M.S. project is focused primarily on endangered Roseate Terns, but other species such as Common Terns, Least Terns, and Royal Terns (among others) stage with Roseate Terns and are part of her observations. Melissa and her field crew also resight color banded Roseate Terns as part of a larger effort to collect information about their demographics and movements.

An Endangered Shorebird Returns to Lake Ontario

8/19/2015

 
PictureEach piping plover chick received colored legbands that identify the location where they hatched. The chick pictured here is 6 days old.
By the early 1980's, habitat loss, human disturbance, and increasing predator populations combined to make the beaches of the Great Lakes unsuitable for nesting by the piping plover.  The entire region contained only 16 nesting pairs when the species was placed under the protection of the Endangered Species Act in 1985, and after 1984 the species completely disappeared from Lake Ontario except during migration.  Thanks in large part to conservation efforts led by Dr. Francie Cuthbert at the University of Minnesota, there are now 70 nesting pairs in the Great Lakes and piping plovers are starting to expand into deserted portions of their former range.   In 2015, for the first time in 31 years, piping plovers nested on the shores of Lake Ontario.      Under the protection of the New York DEC, two eggs hatched at the eastern end of the Lake and one of the young survived the dangerous 25 days from hatching until first flight.  At the invitation of Dr. Cuthbert and the DEC, Dr. Cohen and members of his lab placed colored legbands on the chicks.  We will now be able to identify the fledgling when, hopefully, it has a nest of its own.  In this way, the growth of the recovering Great Lakes population can be tracked and further opportunities to protect habitat can be identified.

Grad Student Pilots PIT Tagging for Tidal Marsh Sparrows

3/20/2015

PhD student Alison Kocek, along with collaborators at the University of Maine, piloted a study in 2014 involving the application of PIT (Passive Integrative Transponder) tags to tidal-marsh sparrows within New York City and southern Maine.  During previous field seasons, multiple recaptures of sparrows (systematically and at nests) throughout the field season led to trap avoidance and possibly increased the risk of nest abandonment by adult sparrows.  To reduce both of these potential problems, Alison chose to attach a PIT tag to a nesting birds’ color band as a novel way to allow researchers to passively identify birds attending a nest.  These tags do not require a power source, are light weight (0.1g), and remain with the birds for their entire lifespan. This reduces potential negative impacts from frequent handling of birds, while allowing researchers to collect more information with less effort than traditional recapture methods.

Alison and fellow researchers applied tags (using epoxy and electrical tape) to the color bands of female saltmarsh sparrows (ME and NY), Nelson’s Sparrows (ME) and hybrids (ME), and male and female seaside sparrows (NY) captured throughout the 2014 field season.  She also banded male seaside sparrows with PIT tags because they are known to occasionally aid in feeding young and are notoriously difficult to capture during targeted netting at nests.  Tags were applied to 88 individuals in New York and 84 in Maine.  Once several individuals were tagged at a study site, researchers began placing RFID (Radio Frequency Identification) reader antennae next to active nests for 15-minute intervals to determine which individuals were attending nests.  To confirm that RFID readers were only capturing the IDs of the attending adult and not another bird passing by, a subset of these same nests were later targeted for netting.  In all instances where targeted netting resulted in a capture, individuals trapped in nets were the same individuals whose PIT tag ID was recorded by the RFID reader at the nest.  Also, in every instance that an RFID Reader was unable to obtain the PIT tag ID of an individual, target netting determined that the attending individual was not marked with a PIT Tag. Thus, these data demonstrated 100% PIT tag readability and accuracy during the 2014 field season in both New York and Maine.  

Alison plans to continue this work in 2015, and will tag new individuals as well as examine return and retention rates for previously tagged birds. Alison and Dr. Cohen conduct this research as part of the Salt Marsh Habitat and Avian Research Program (SHARP), a collaborative effort among several universities and agencies in the Eastern U.S. SUNY ESF’s portion of the project is funded by the U.S. Fish and Wildlife Service's Hurricane Sandy recovery program.

New England cottontail research featured in New York State Parks "Nature Times"

9/4/2014

 
The recent edition of the New York State Parks publication "Nature Times" details research being done by Ph.D. student Amanda Cheeseman on predator communities in New England cottontail habitat.   Amanda and her research team are using camera traps and avian point surveys to compare occupancy rates of predators among different potential cottontail habitat areas.  Her research will inform restoration efforts currently planned by the agency.

Graduate student Maureen Durkin's project evaluating the impacts of road mortality to the Snowy Plover population and other wildlife at Gulf Islands National Seashore, FL was featured in a piece urging local beachgoers to be mindful of nesting birds this holiday weekend. Audubon Florida and the National Park Service also highlighted the importance of respecting wildlife by following speed limits in the park, staying away from posted nested areas, and keeping pets off the beach. Maureen is conducting her dissertation research at Gulf Islands, where mortality of shorebirds and other wildlife on park roads is an ongoing issue of concern. Ultimately, this research aims to quantify road mortality and identify contributing factors to provide information that may aid the National Park Service in balancing management of shorebird populations and recreational use. Check it out here.

Dr. Cohen has received funding from National Fish and Wildlife Foundation's Gulf Environmental Benefit Fund to continue studying wildlife road mortality at Gulf Islands National Seashore, FL. The National Fish and Wildlife Foundation (NFWF) received 2.5 billion dollars as the result of a plea agreement resolving the criminal case against BP for the 2010 Deepwater Horizon Oil Spill. This fund will be directed towards projects that will benefit the Gulf Coast's natural resources over the next five years.  SUNY ESF collaborated with Audubon Florida to submit a proposal for the first round of funding in November 2013, which was successful. Preliminary results from a summer 2013 pilot study funded by the National Park Service found road mortality of shorebirds and seabirds at Gulf Islands National Seashore is likely higher than previously counts indicated, and that beach mice and reptiles are also affected. This study will also build on prior work on this site and continue to investigate snowy plover survival and reproductive success. This will allow for determination of the impact road mortality may have on snowy plovers at the population level.

Current lab member Maureen Durkin, who has spent the past 2.5 years working on her M.S. on human disturbance to snowy plovers at several sites in Florida, including Gulf Islands, will take on this project for her Ph.D. Maureen carried out the field work for the pilot study last year, and is excited to continue working with our partners at the National Park Service, Florida Fish and Wildlife Conservation Commission, US Fish and Wildlife Service, Florida Parks Service, and Audubon Florida. This year's field work will begin in early April and continue through August.

Field Update: Michelle Stantial

6/9/2013

For her second field season studying piping plover movements and flight patterns in Massachusetts and New Jersey, M.S. student Michelle Stantial was able to build an automated telemetry system for monitoring radio-tagged plovers at her study sites. Michelle was awarded grants from the Goldenrod Foundation and the Garden Club of America to fund the telemetry station.

She says of the system, "It helps us detect movements of piping plovers during times of poor weather and low-light conditions (times when birds are more susceptible to collisions with turbines).  We leave it out on the beach and let it 'listen' to a bird with a telemetry unit for a few nights in a row, then we switch to another individual."

Michelle's research will examine the implications of wind turbines piping plovers, specifically examining the potential for collision mortality if turbines are built in or near their habitat.
