The results from the 116th Annual Audubon Christmas Bird Count are in! The 2015 Lower Hudson count took place on Sunday, December 20th, a cold but clear day. The Lower Hudson count circle (code: NJLH) includes Manhattan and parts of Hudson and Bergen counties in New Jersey.


With the help of 174 participants, we counted a total of 27,167 birds and 96 species this year. Though a little lower than last year’s numbers (30,641 birds and 111 species), there were still a lot of birds counted, showing that winter can be anything but boring!


Counts took place in Central Park, Inwood, Harlem, Riverside Park, Randall’s Island, Bryant Park, Madison Square Park, Stuyvesant Town & Cove, East River Park, Lower Manhattan, and many locations throughout New Jersey (see map below). We thank all of the count leaders who made this year’s count possible, including a count during “count-week” on Governor’s Island.

Black Skimmer Round Up!

NYC Audubon Conservation Biologist Debra Kriensky reports on an exciting new conservation partnership project:


By the end of August, we are always sad here in the office that our busy field season is coming to an end. Our American oystercatcher chicks have fledged, there are no more herring gulls to band on the green roof of the Javits Center, and our great egrets are already off and flying around Jamaica Bay. That’s one reason why, when asked to help band black skimmer chicks out at Nickerson Beach in Nassau County, Long Island, just outside our territory, we jumped at the chance! With John Zarudsky and his crew from the Town of Hempstead, along with Jason Smith and his team from NY State Department of Environmental Conservation (DEC), we headed out early Tuesday morning to the colony of approximately 600 pairs of skimmers on Nickerson Beach.


The plan was to quickly set up a drift fence at the edge of the colony to act as a boundary, to prevent the chicks from running out of the colony where they could fall prey to gulls. Once we set up, it worked better than we could have expected. Within a few minutes, we were able to herd close to 100 chicks inside the u-shaped fencing. We closed off the opening in the fence, turning it into a pen with the chicks inside. The adults stayed nearby while we quickly banded the chicks, releasing them back into the colony as soon as they were banded. The chicks, fast runners but still not able to fly, resemble drab versions of the adults, and lack the unique bill that make skimmers unmistakable. At three to four weeks old, chicks have a large bill, but it is still dark and the length of the top and bottom are still equal. With age, the lower mandible will eventually grow longer than the upper.


Each chick was banded with a US Fish & Wildlife metal band on its left leg, and those with big enough legs received a bright yellow field-readable ID band on their right leg. There were a few thin-legged chicks whose yellow bands slipped right off their feet! The plan is that the Town of Hempstead will find out where their skimmers are going during the rest of the year, and to see how many chicks return as adults to breed in their natal colony.


In all, we were able to band over 80 skimmer chicks in a matter of a few hours—no small feat given that without the fence, this would have taken several days to accomplish. While we were there, we didn’t see any gulls or any aggressive encounters with territorial adult skimmers, and young birds were soon reunited with their siblings and parents—a good sign for young chicks, which can become easy prey for gulls or aggressive neighbors. It was a rewarding day working with our colleagues at the DEC and Town of Hempstead (and the skimmers of course), and a successful end to our summer field season.


ACT NOW to Save Wild Birds!

Wild birds are under siege. In New York State, they are threatened by a feral cat trap-neuter-return (TNR) bill that offers no provision for excluding return to critical wild bird habitat. Nationwide, they are threatened by amendments to appropriations bills that would prevent all enforcement of the Migratory Bird Treaty Act (MBTA). Please take a moment to voice your opposition. Your action is critically needed!


TNR in New York State
Members residing in New York State, please visit to contact and ask Governor Andrew Cuomo to veto the recent TNR bill, which has passed both the Assembly and Senate despite the efforts of bird and conservation organizations.


Suggested language for your message:


         Please veto Senate Bill 1081 (Senator Marchione) and Assembly Bill 2778 (Assemblyman McDonald), an act to amend the agriculture and markets law, in relation to community based initiatives for the purpose of trapping, neutering, vaccinating and returning feral cats to the area from which they were trapped. This practice is known as TNR.

         TNR has not been scientifically proven effective at reducing the feral cat population, which poses great risks to New York’s wild bird populations, other wildlife, and public health. In addition, this practice conflicts with other sections of Agriculture and Markets law that prevent the release of animals once in custody of a shelter or animal control officer.

         Worse, there is no provision in the Bill to prohibit or prevent the return of feral cats to critical natural areas. These include Important Bird Areas and New York State Bird Conservation Areas, which have been established and are funded to protect wildlife habitats, as well as nesting and migratory species, some of which appear on the New York State Department of Environmental Conservation’s list of Endangered, Threatened, and Special Concern Species.

         We urge you to please veto this Bill!



Congressman Jeff Duncan’s attack on the MBTA
Please visit, enter your address, and follow the links to your US Senators to submit requests that they oppose any amendments to appropriations bills that contain Congressman Jeff Duncan’s anti-MBTA-enforcement amendments and to vote against any legislation that contains his anti-MBTA-enforcement riders or amendments. Duncan’s efforts are profoundly dangerous to bird conservation.


Suggested Language for your messages:


         For nearly 100 years the Migratory Bird Treaty Act has been a pillar of Americans’ collective resolve to make a place in our world for birds and their habitats. I am writing to urge you to oppose any efforts to include the House-passed Duncan “Bird Killer Amendments” to the Senate versions of both the Commerce-Justice-Science bill and the Interior-Environment bill. If these amendments had been in effect when the 2010 Deepwater Horizon blowout occurred, BP would not have been subject to prosecution for the killing of millions of birds.

         I know I can count on you to uphold the timeless bipartisan commitment to conserving our nation’s wildlife for future generations.

NYC Audubon’s Susan Elbin and colleagues Nellie Tsipoura and John Brzorad share an exciting new partnership project:

A new era of technology has been added to the NYC Audubon/NJ Audubon Harbor Herons foraging surveys. For the past several years, dedicated citizen science volunteers have spent hundreds of hours collecting data on Harbor Heron foraging locations in New York City and NJ. Now two of our birds are part of a larger study being done by scientists at Lenoir-Rhyne University (Dr. John Brzorad), Friends University (Dr. Alan Maccarone), and NJ Audubon (Nellie Tsipoura). (Note: John and Al did some of the original Harbor Herons surveys in the mid-1980s).


On June 25 and 26, two adult great egrets were captured at Wolf’s Pond, Staten Island, and fitted with solar-powered GPS/GSM (Global Positioning System/Global System for Mobiles) transmitters. The birds’ transmitters send text messages indicating their location, which are then displayed on virtual maps at The two birds, Clare and Edward, have been “adopted” by local classrooms on Staten Island (Mrs. Theresa Kutza, New Dorp High School and Mrs. Mary Lee, St. Clare’s School) and by citizen scientist volunteers. Clare is definitely part of our breeding population:  She frequently sends messages from Hoffman Island. Edward spends his time on the Jersey side of the river, but just at press-time, has also visited Hoffman. You can see for yourself what Clare and Edward have been up to by clicking here.  (If you click on either “Clare” or “Edward” on the left-hand side, the name will turn blue, and the bird’s flight path will appear on the map. Zoom out to see the entire area the birds have traveled. Note that due to a technical glitch, at the moment both birds are labeled as great blue herons.)

This work was funded by the US Forest Service, the NJ Division of Fish and Wildlife, and private donations to NJ Audubon, and done in cooperation with the New Jersey Audubon Society, New York City Audubon, and the NYC Department of Parks and Recreation.





Birds & Blizzards: Adaptations of Wintering Birds

NYC Audubon Director of Conservation and Science Susan Elbin shares how birds are able to handle the more severe conditions of the winter season

After several recent snowstorms (with more predicted for this weekend), maybe some of us have been wondering about the birds: my feeders were full of birds, but now they are deserted. What do birds do in bad weather?


First let us reassure you: birds have been around for more than 60 million years! They have adapted to different climate regimes and have learned how to survive inclement weather. Most birds deal with the cold weather by migrating south. The birds that come to New York City or stay here through the winter have a variety of behaviors that keep them warm and dry. A few things they do:


  • Fluff up their down feathers and keep their body feathers waterproof. Some birds molt additional down during the winter.
  • Cover exposed skin with feathers. Some birds will tuck their bills under a wing or tuck one leg up close to its body. Some birds can stand on ice without freezing their feet because of specially adapted circulatory system called “counter current.”
  • ‘Hunker down’ in a protected spot until the storm passes.
  • Huddle! Birds will often sit close together – closer than they would in temperate weather.
  • Produce their own body heat by shivering.
  • Eat a lot of high-calorie food.
  • Chill out: some birds slow down their metabolism and go into a state of torpor.


Unfortunately, despite all of these adaptations and behaviors, some birds don’t make it. While wintering birds have evolved to survive without the help of supplemental feeding by people, if you do feed the birds in the winter time, make sure to keep your feeders consistently stocked until spring. If you can provide fresh water, that’s all the better.

Project Safe Flight Update: Fall 2014


Research Assistant Debra Kriensky provides an overview of this fall’s Project Safe Flight results:


Fall migration has come to an end, and we have now tallied up our findings from this autumn’s Project Safe Flight efforts. In all, a total of 78 dead and injured birds were found by our dedicated Project Safe Flight volunteers this fall, who go out every week during migration rain or shine to help us determine where birds are colliding with glass around the City. Monitoring took place at several sites this fall, including the Metropolitan Museum of Art (MET), Bryant Park, and the Richard Meier building on Prospect Park. Several new sites were monitored this year as well, such as Lerner Hall on Columbia University’s campus and the Ford Foundation Building. The MET and Bryant Park continue to be collision hotspots for migrating birds. Even with fencing obstructing parts of the route at the MET for the first few weeks of migration, our volunteers still found 50 birds there over the course of 10 weeks.

In addition to our Project Safe Flight data, our new online data entry tool, D-Bird, provided us with information about dead and injured bird sightings from all over New York City and for the first time, we were able to combine that information with our Project Safe Flight data. What we found was alarming: a total of 237 dead and injured birds from August to early December. Continue reading ‘Project Safe Flight Update: Fall 2014’ »

Hooked on Herons: Confessions of a ‘Citizen Scientist’

By Gail Karlsson, Harbor Herons Foraging Study Volunteer


When I first stopped by  NYC Audubon this past May, I didn’t realize I was in danger of developing a serious addiction problem. You may scoff, but first hear my story.


I was initially exposed to herons in the Caribbean, and soon found myself searching for sources closer to home. Not so easy in Manhattan, though I did once spy a couple of great egrets by the pond at the south end of Central Park.


Then one day a friend passed me a copy of the NYC Audubon newsletter and I saw a notice about a Harbor Heron Foraging Study training—that very night! Hours later, with high expectations and a sense of destiny, I found myself in a small room cluttered with bird books. About 15 of us sat quietly on folding chairs, nervously checking each other out, not sure what to expect. Continue reading ‘Hooked on Herons: Confessions of a ‘Citizen Scientist’’ »

2014 International Coastal Cleanup Day Report

On September 20, NYC Audubon took to the shores of New York City for this year’s International Coastal Cleanup Day. The annual event is a global volunteer effort uniting hundreds of thousands of volunteers from across the globe to help clean up our shorelines and oceans. For this year’s Cleanup Day, we organized not one but two different cleanups of City beaches that are vital for migrating and nesting shorebirds: Jamaica Bay’s North Channel Bridge Beach (with American Littoral Society and National Park Service) and Pelham Bay Park’s Orchard Beach (with New York City Parks and Recreation).


Volunteers came out in record numbers for this year’s New York City cleanups: 111 volunteers worked long hours diligently picking up trash from the beaches. The Boy Scouts of America, Girls Scouts Troop 4623-4587, Hunter High School Environmental Club, the Mitsubishi Corporation, and Volunteer for Wildlife were among the groups lending a hand at Jamaica Bay, while CubScout Pack 304 based in PS304 Bronx was instrumental in our cleanup of Orchard Beach.


Between the two cleanups, this year we were able to remove 1,726 pounds of trash. That’s almost a ton! At our North Channel cleanup alone, we picked up 321 plastic grocery bags, 454 plastic and glass bottles, 730 cigarette butts, 2,302 glass pieces…and one teddy bear!


Thanks again to everyone who made this year’s International Coast Cleanup Day our most successful ever. New York City shorelines provide valuable habitat to wildlife, including migratory and beach nesting birds. The dedication and hard work of all those who volunteered this year will improve City shorelines for birds, and people too.

Finally, these cleanups could not have happened without the hard work of Adriana Palmer and Terra Weiland, our beach captains for the North Channel and Orchard Beach cleanups, respectively. Thanks to both of them for organizing these two very successful events.

Tribute in Light 2014: A Problem-Free Night for Bird Migration

Tribute in Light Beams © Debra Kriensky

Tribute in Light Beams © Debra Kriensky

On September 11, 2014, NYC Audubon staff members were joined by 19 dedicated volunteers for the annual monitoring of the Tribute in Light memorial. Every year from 8pm to 6am the next morning, our monitors watch the light beams carefully to make sure migrating birds are getting through safely. On heavy migration nights, it’s possible for hundreds or even thousands of birds to be seen circling the lights at a time, disoriented and likely to exhaust themselves or suffer injury. When such high numbers of birds are seen ‘caught’ in the lights, the Municipal Arts Society of New York, which founded the Tribute, cooperates with us and turns off the light beams for a brief period to allow the birds to pass through and continue their migration safely. Thankfully, this year we only counted a handful of birds at any one time throughout the night, and the lights were kept on the whole time.


Even with all the modern technology available today, it’s still difficult to accurately forecast the weather, not to mention bird migration! For days and even hours leading up to the Tribute in Light monitoring, we were not sure what to expect that night. Weather reports earlier in the week had called for rain all night on September 11th, which though less than ideal for the volunteers is actually a good thing for the birds. Heavy rain overnight would likely mean that migrating birds would stick around another day to wait for better weather to continue their journey south. By Thursday morning, however, the forecast had changed and aside from a chance of rain early on in the night, it was beginning to look like we would see clear skies instead. At the same time, migration forecasts were predicting moderate to heavy migration activity in the Northeast, including in New York City.

Everyone on the ground was prepared for a situation like those seen in years past, when we have had to request that the lights be shut down several times due to thousands of birds circling in the light beams. As typically happens though, conditions can change at a moment’s notice. While it did end up being a clear night, only a few birds—and bats—passed through the lights. In fact, the highest number of birds counted in the lights at any one time was only 18. It was a great relief to hear mid-monitoring that while it was still a heavy migration night, the birds had flown just west of New York City, missing the lights almost entirely.

Greenpoint’s McGolrick Park Transformed into an Urban Oasis

NYC Audubon Intern Melanie del Rosario reports on the planting of a quarter-acre native plant garden in McGolrick park, and how the garden will benefit birds, wildlife, and the Greenpoint community:

A group of NYC Audubon staff and a team of dedicated volunteers got their hands dirty in Greenpoint, Brooklyn on June 28 and 29, planting a quarter-acre native plant garden in McGolrick Park. After much planning and hard work by NYC Audubon Research Assistant Kaitlyn Parkins, the previously sparse, grass-covered southwest corner of the park has been transformed into an urban oasis designed to attract a variety of wildlife species and promote biodiversity within the park. The new garden, funded by the Greenpoint Community Environmental Fund, is an ongoing project that will engage the local community in caring for the park and increase quality of life for both people and wildlife in Greenpoint.

About 40 volunteers from the Greenpoint area came out for the weekend planting event, and put over 4,000 plants into the ground! We planted native wildflowers such as New York asters and black-eyed susans, along with shrubs such as lowbush blueberries, ferns, and grasses (including the broomsedge pictured on the right).

We carefully selected plants native to the New York City area that will provide food and habitat for birds as well as beneficial insects, pollinators, and bats. Many migrating songbirds are experiencing population declines due to poor quality stopover habitat. Some of these birds travel over 1,000 miles without stopping, so providing them with sufficient food and water is crucial for their nesting success when they reach their breeding grounds. The McGolrick Park garden will provide high-quality habitat and food sources for both permanent residents and migrating birds throughout the year.

In addition to benefiting wildlife, the garden will also enhance the Greenpoint community for anyone who enjoys getting in touch with nature. We hope that everyone who passes through McGolrick Park will enjoy the natural beauty of the garden while learning about the importance of native plants and wildlife.

Although native plants are relatively maintenance-free once they are established, our new plants could use extra help to ensure they survive their first year. If you are interested in helping care for the garden, email to learn more.
