Central Park Fall Migration Walk with Richard Davis, Alan Drogin, and Kevin Sisco, 10/7/2025

Registrar: Sarah Dahl
Participants: 40
Weather: Cloudy and low 60s at the start
Bird Species: 64

A mild, somewhat warm fall day greeted an energetic group of 40 birders. Though a few participants were delayed by early subway snags, all eventually arrived in good spirits, ready to explore. Highlights of the day included excellent looks at Orange-Crowned Warbler, Philadelphia Vireo, and White-eyed Vireo. A Cooper’s Hawk added excitement as it was mobbed noisily by a large flock of European Starlings.

Inwood Hill Park with Loyan Beausoleil, 10/5/2025

Registrar: Lisa Kroop
Participants: 18
Weather: 66°F–79°F, sunny with haze; light breeze, 2 mph NE
Bird Species: 41

It felt like a summer day, especially as the morning progressed, but we were now into October and some trees were starting to show signs of fall. It was close to high tide, and at our first stop we saw many sleeping Mallards concentrated along the far shore of the salt marsh. As it was quiet, with little activity, we moved on to a small fenced-in meadow nearby, adjacent to a large grass field, to see what we might find there. We took our time, carefully inspecting the House Sparrows that were energetically foraging in the grass along the fence. Over time, among them and nearby, we found a Swamp Sparrow, a couple of Savannah Sparrows, a Chipping Sparrow, and a Palm Warbler. We looked for the Indigo Bunting that Loyan had spotted before the walk, but we were unable to relocate it.

Continuing onward, soon reaching the corner of the field, we left the bay behind us and paused again. This time we found the action along the wooded edge of the field, first with sparrows, followed by the arrival of a juvenile Red-tailed Hawk who perched very close to us on a sturdy plant stalk that had just moments before been vacated by a Song Sparrow. And while the Red-tailed Hawk perched, a Belted Kingfisher alighted onto a snag nearby.

We entered the Clove, a deep, narrow valley between steep rock ridges and woods of mature, tall trees. In the heavily shaded and cool Clove, Blue Jays called loudly all around us. We paused several times to search for other migratory birds in the sunny patches high in the treetops, but didn’t find any. Then, to the delight of everyone, a warbler was spotted foraging in the path far ahead of us—a female Black-throated Blue Warbler. It continued there for several minutes, briefly moving out of the shade into a bright sliver of sunlight, and then flew into the understory and out of sight.

Observing the vista from the Overlook Meadow, we hoped to see raptors moving over the Hudson River. The view was beautiful, but we saw barely a flying bird, and no raptors. We resumed our walk back into the woods. We had heard and seen quite a few Red-bellied Woodpeckers by this time. Yet another one called—we located it, saw that it had an acorn in its bill, and watched it fly to another tree and cache the acorn under the peeling bark of the trunk—fascinating to watch.

We followed the trail downhill to underneath the Henry Hudson Bridge that overlooks Spuyten Duyvil Creek. As we gazed out at the view, noting a distant Great Blue Heron, we heard the loud and clear croaking of a raven close by. There were two of them, directly overhead, perched on the supporting framework of the bridge. And across the creek, perched on the roof of an apartment building, was a third.

As we neared the end of our walk, we paused to observe a couple of phoebes, and then gathered at Shorakkopoch Rock to thank Loyan for leading us on a wonderful birding trip through Inwood Hill Park.

Watch Hill on Fire Island with Paul Sweet, 9/28/2025

Registrar: Christina Black
Participants: 12
Weather: 
Sunny, very warm, 75-85 degrees
Bird Species:
42

For five delightful hours, Paul Sweet led our group through the area of the Fire Island National Seashore east of and in Watch Hill, NY. Also providing birding IDs and local commentary was Deborah Swamback, a Queens County Bird Club member who birds in and around Watch Hill and Davis Park for about half each year.

We spent most of the day along the walkway that leads through the sheltered dune areas between the ocean and the bay, which include low tree/bush cover, some fresh water ponds, and a large saltwater marsh. The shadier sections were fairly birdy, including a number of the warblers, along with scolding Gray Catbirds and singing Carolina Wrens.  After about 90 minutes, the group walked up to a high platform overlooking the marsh, where a small Goldfinch, watching us from a nearby bare branch, contrasted with a Northern Harrier soaring overhead. Eventually, the group made it down to the marsh, which had less bird activity but included some Egrets and a Great Blue Heron near a pond, and Northern Flickers dashing about; it was too late in the fall for Seaside or Saltmarsh Sparrows.

After lunch, the group spent time on the beach discussing Gull and Tern IDs, before heading back to the woods and marsh. A first-of-season Dark-eyed Junco was spotted, and, later, the final bird of the day was a Palm Warbler (Western) right after a pair of Least Sandpipers were seen on a wee marsh beach.

Weather:
Cloudy, winds up to seven miles per hour, temperatures ranging from 64 – 79 degrees
Bird Species:

After meeting our leader, Ursula Mitra, the group headed up to the Great Hill to begin exploring the North End of Central Park.  We quickly observed a large number of Northern Flickers flying overhead, as well as several Northern Parula moving within the trees.  The Northern Parulas were the first of fourteen warbler species we identified over the course of the day. 

At The Pool, we had great looks at three Green-winged Teal associating with a group of Mallards, allowing us to fully appreciate the smaller size of the teals.  Also seen were Northern Waterthrush, a Gadwall, and an additional warbler species.

We moved on to some of the more wooded areas, including the Lily Pond, where we saw a Rose-breasted Grosbeak, additional Scarlet Tanagers, Black-and-white and other warblers, and Red-eyed Vireos.  One participant also spotted a White-eyed Vireo.  Additionally, we had good looks at a Cooper’s Hawk swooping overhead.  At the Block House, we spotted Magnolia and other warblers, Cedar Waxwings, and at least one Red-tailed Hawk.

Our walk then took us through The Loch, where we continued to add to our warbler count.  After our lunch break at the Green Bench, we headed over to the Nursery and Compost areas, where we were surprised to find an Indigo Bunting.  In the nearby Wildflower Meadow, we spotted a Pine Warbler that had been reported earlier by others. 

We ended our day back at The Pool, where we sat for a bit at the Bathing Rock and watched Common Yellowthroats and several other species splashing in the water.  Those who stayed until the end birded for close to eight hours!  A big thank you to Ursula for leading another great walk.

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.

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.
