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

Registrar:  Suzanne Zywicki
Participants:
11
Weather:
Clear skies, temperature ranging from 58 to the mid-70s
Bird Species:
42

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!

Randall’s Island with Mary Beth Kooper, 9/11/2025

Weather:
Sunny, light wind, temperatures ranging from 60-80 degrees
Bird Species:
36

Our small but eager group met at 7 am to begin our exploration of Randall’s Island.  We headed out walking slowly through the Sunken Meadow Fields, keeping an eye out for sparrows.  We soon spotted two interesting birds perched in a tree not too far from the Tennis Center and worked through their field marks to identify them.  They proved to be the first of eight Savannah Sparrows we saw throughout our walk.  We continued walking along the East River, where we saw additional Savannahs, as well as a Killdeer on one of the ballfields and a number of Mockingbirds.  As we walked, a mixture of Fish and American crows were often seen and heard overhead.  In the Bronx Kill area, we first glimpsed a Spotted Sandpiper, another Killdeer, and a Kingfisher, soon followed by an excellent view of a Yellow-crowned Night Heron and two more Kingfishers chasing each other.  We continued along the path bordering the Bronx Kill, where many in our group saw a small flock of Cedar Waxwings fly overhead.  When we reached the Golf Center, we fanned out to try to get a good look at what might be hiding in the grass.  While we didn’t see many warblers or flycatchers, we were treated to at least three American Kestrels perched around the perimeter.  We then headed to the Little Hell Gate Salt Marsh area.  Unfortunately, this area did not prove to be very birdy, so we decided to end an otherwise excellent morning of birding.

Weather: 61F-69F and sunny, light breeze
Bird Species: 59


It was a beautiful September morning, and 45 birders gathered at 7:30 a.m. to see what migration would bring. The walk began a bit slowly in Strawberry Fields, with only a few warblers, but everyone was delighted by a Ruby-throated Hummingbird in the Cardinal Flowers in Shakespeare Garden. As it turned out, it was an excellent day for hummingbirds! Several more were spotted feeding on jewelweed at Tupelo Meadow, with some chasing and sparring high in the air, providing a lively and memorable show. Warbler activity picked up in the Ramble, where many Black-and-white Warblers and American Redstarts were seen, bringing the total for the morning to 14 species. That evening marked the first in-person monthly Linnaean meeting since before the pandemic, and we were especially delighted that our guest speaker, Dr. Erik Katovich, was able to join us on the morning walk.
