Cloudy, winds up to nine miles per hour, temperatures ranging from 63 to the low 70s

After having to delay our walk by a day due to rain, our small but determined group travelled to Rockefeller State Park Preserve in Westchester County to meet up with Anne Swaim, Executive Director of Saw Mill River Audubon.  The park, which is over 1,700 acres of primarily hardwood forest, has been designated an Important Bird Area by the National Audubon Society.

As we were setting off on our walk, we were treated to the sight of over eighty blue jays migrating together overhead.  On the way to Swan Lake, we saw several species of warbler, Tufted Titmouse and Black-capped Chickadee (both first of season for many of us), Red-eyed Vireo, and heard multiple Carolina Wren.  Another highlight was two Common Ravens flying overhead, communicating loudly to each other as they flew along.  Unfortunately, Swan Lake itself was very quiet, though we did see a lone female Wood Duck paddling along.

As we continued through the forested areas and meadows, we also observed a number of Eastern Bluebirds, several species of sparrow, including Savannah and Eastern Towhee, and three Scarlet Tanagers.  We debated the identification of one of the tanagers, considering both Scarlet and Summer varieties, and landed on Scarlet after a close review of photos taken of the bird.  One of the wooded trails yielded a variety of woodpecker species, including Red-bellied, Downy, Hairy, and Northern Flicker.  While we all heard the drumming of a Pileated Woodpecker, only one sharp-eyed birder actually saw the bird.

We ended our trip mid-morning, with a few individuals heading off to nearby Croton Point Park to continue birding on their own.  We appreciated Anne’s knowledge of the park and her enthusiasm for helping us to explore it.

Central Park Fall Migration Walk with Ken Chaya, Richard Davis, Elijah Shiffer, and Kevin Sisco, 9/23/2025

Registrar: Yeree Shim
Participants: 36 
Weather: mid 60s to mid 70s, partly sunny to sunny with a little breeze in the morning.
Bird species: 50

It was a beautiful fall day for the Central Park fall migration series. Birders split into three groups of approximately 10 participants each and explored Strawberry Fields, Hernshead, The Ramble, and the area south of Turtle Pond. The day started slowly, with few birds observed in Strawberry Fields. Activity increased in The Ramble, where Evodia Field proved to be the most productive spot of the day.

Beginners Bird Walk in the North End with Linda LaBella, 9/21/2025

Registrar: Savannah Conheady 
Participants: 2 
Weather: A touch overcast with a high of 68F 
Bird Species: 29 
 
The Beginners Bird Walk began with an introduction to ethical birding, an overview of fall migration, and a preview of the species we might encounter. From there, we headed to the Pool, where we practiced spotting birds and describing their locations to others. As we continued along, we observed a variety of birds while learning how to distinguish between males and females and how to identify different species. It was a beautiful and educational day.

Starr Saphir Fall Migration Walk with Richard Davis, 9/20/2025

Bird Species:

Twice each year, The Linnaean Society holds walks in memory of Starr Saphir, a local birding legend, who led walks in Central Park since the ‘70s.  We started the day by talking about Starr and her approach to birding.  One member of our group had birded with Starr, and two others were familiar with her from watching Jeff Kimball’s documentary Birders: The Central Park Effect, in which Starr appears.  Inspired by Starr, we headed off into Strawberry Fields to begin our walk through The Ramble and nearby areas.  Almost immediately, we began to see a variety of warblers, including Bay-breasted, Northern Parula, Common Yellowthroat, and American Redstart. We also saw Red-eyed Vireos, a Hermit Thrush, and various other birds.  While on the Oak Bridge, one sharp-eyed birder spotted a Chestnut-sided Warbler, and we all got good looks at the bird.  Our visit to The Point helped increase our warbler total for the day– thirteen in all.  Other highlights included finding several hummingbirds in the jewelweed in Tupelo Meadow, seeing a Red-tailed Hawk diving at high speed in search of its prey and another perched low on a tree branch, and observing an American Kestrel in an aerial battle with another bird.

Central Park Birds & Brews Nighthawk Edition with Alan Drogin, Gillian Henry, and Amanda Bielskas, 9/17/2025 

Registrar: Amanda Bielskas
Participants: 12 
Weather: mid 70s, cloudy with a chance of rain, but it held off
Bird species: 17
 
We had a great evening walk in Central Park before it got too dark for birding and then made our way to a bar on Amsterdam Ave. for some libations. We started at 81st street and headed into The Ramble where we saw several Ruby-throated Hummingbirds in a hedge row full of jewelweed, which was also hosting a couple of Rose-breasted Grosbeaks. We gathered a couple of warbler sightings on our wanderings in The Ramble and gathered several additional species along the path on the south shore of Turtle Pond. As we approached closer to the Castle, the front half of the group got a quick glimpse of a Common Nighthawk as it flew into and out of the brush, but it was only briefly seen. We headed up to the Castle overlook to hopefully spot some additional nighthawks, but the sunset came pretty quickly without any additional sightings. On our way out of the park, we stopped on some rocks to check out the Chimney Swift roost in the 80s, but we only saw a few lingering birds heading into the chimney as dark was falling. Though we had heard them in good numbers chattering over the course of the whole walk. At the end of the walk, we headed out for drinks on the Upper West Side, and good conversation was had by those who participated.  We look forward to the next fall Birds & Brews in Brooklyn in October on a weekend when we won’t be as pressed for time by a setting sun!

On a morning that started cloudy but soon was warm and sunny, 34 birders divided into 3 groups and found many species.

Prospect Park Fall Migration Walk with Tom Stephenson, 9/14/2025 

Registrar: Amanda Bielskas
Participants: 13 
Weather: mid 60s to mid 70s, partly sunny to sunny with a breeze.
Bird species: 43
 
We started at Grand Army Plaza and went to the Vale of Cashmere. We continued along some of the lawns and tried for the bathrooms, but they were not open as they should have been.  We skirted Sparrow Bowl and went a bit up the switchbacks. Then we headed towards the Lake. We stopped at the Well House bathrooms and skirted the south end of the Lake and headed east. We birded all along the Lake shore, which was quite birdy at the southern end. We finished up birding at the Green Roof of the skating rink, which was a bit noisy from an event, and we headed out of the Park at the Lincoln Road entrance. We had a relatively low volume of birds, but a good number of species over the course of the morning and into the early afternoon. We also got great lessons from the leader, Tom, on the distinguishing characteristics of some of the tricky thrushes and fall warbler plumages. We had quite a few of each of Red-Eyed Vireos, Black-and-white Warblers, American Redstarts, and Yellow Warblers. For the day, we counted 15 warbler species overall, which was pretty good for an early fall migration day.

Green-Wood Cemetery with Rob Jett, 9/13/2025

Registrar: Gillian Henry
Participants: 17 participants
Weather: 65 ℉, mostly clear with mild south eastern winds.
Bird Species: 44 species

On a clear, gray, cool September morning, sixteen eager birders met our guide, Rob Jett, and embarked on a pleasant walk through historic Green-Wood Cemetery in search of fall migrants. The day was relatively quiet, but there were many spectacular highlights, including Hooded- and Nashville- warblers, immature Cedar Waxwings, and a Ruby-throated Hummingbird caring for 2 juveniles on the nest!
As usual, we were also treated to the unmistakable sight and sound of the famous Monk Parakeets tending to their large, colonial stick nest above the main entrance. In total, we observed forty-four species, making for a delightful day of early fall birding!
