Shawangunk Grasslands NWR and Wallkill Marsh with Tod Winston, 5/30/26

Registrar: Christina Black
Participants: 13
Weather: Unseasonably cold in the 40s & 50s, with intense wind gusts and occasional sprinkles
Bird Species: 61

Tod Winston led us on an amazing day of birding in several locations, with everyone braced against unusually chilly weather for late May. Our full day of birding began at 7:30 a.m. at the Shawangunk Grasslands, with everyone bundled up against the weather. Happily, even the wind did not deter the birds, with many ably clinging to wildly gyrating reeds and branches throughout the day. Fairly quickly, the group found two of the key targets of the trip—singing and displaying male Bobolinks and nesting Eastern Bluebirds. The small and reedy-voiced Grasshopper Sparrow took a bit longer, with one turning its back to us (and therefore not 100% identifiable) but then, thankfully, another perching nearby a bit later for a view through scopes.

As we made our way down the trail to check the grasslands and its wooded border, we watched Tree Swallows and Purple Martins swoop over the fields and a female American Kestrel repeatedly hovering near her nest box. Other sightings included Red-winged Blackbirds and Song Sparrows. An accipiter sped by, not allowing enough time for a Sharp-shinned vs Cooper’s ID. Finally, two Eastern Meadowlarks were also eventually sighted, first after landing in a distant tree and then giving a better view when they melodramatically dashed by us with a flash of yellow. Further down the trail, we spent some time debating the identification of a flirty but silent empid, flycatching in and out of some bushes, without a clear decision between Alder or Willow.

As the main trail quieted down, and with the wind picking up, along with occasional drizzles, the group decided to shift focus and walk up the refuge’s entry road. We had excellent views of the Purple Martin colony, huddled against the cold in their “condos”. Along this road the group also saw Yellow Warblers, American Goldfinches, a Northern House Wren, Chipping Sparrows, and another empid, likely feeding its young. Finally, circling back to the path along the pond, we were treated to a very cooperative Willow Flycatcher that darted back and forth across the water, providing close views when perched.

After attempting lunch in the chilly gazebo, everyone swiftly retreated to their cars for a while to eat and warm up. Then we headed off in a short car caravan through the neighboring Blue Chip Farms property, well timed just as the light drizzle turned to rain. This area did not prove as productive as in previous years, but some participants saw or heard a Downy Woodpecker, Barn Swallows, and an American Goldfinch, mostly from the car.

Liberty Loop in Wallkill Marsh, our final destination of the day, has been in recent years a reliable spot for nesting Sandhill Crane and Common Gallinule. Despite much walking, scanning, and listening, however, we did not detect either of these species, but were ultimately rewarded with a number of other interesting wetland and songbirds. The parking lot platform yielded mostly a large Northern Watersnake slithering through the mild current, and then a flock of 30 peeps fluttering north.

Although the sun was coming out and despite unabating winds, the group decided to walk along the west side of the marsh. One or more Marsh Wrens were heard murmuring, though none popped up from the grasses, and a number of deer, including a fawn, were enjoying the more solid ground of little islands in the marsh. Avian activity picked up along the walkway, with woods on one side and marsh areas with various scrubby trees on the other. Species seen and heard included Wood Thrush, Eastern Warbling Vireos, and Cedar Waxwings; then as we officially crossed into New Jersey, Indigo Bunting, Red-breasted Grosbeak, and Baltimore Oriole were added to the mix. As the view of the marsh area opened up again, scanning for the elusive Sandhill Cranes yielded the sight of 55 feeding Least Sandpipers who were keeping company with three Semi-palmated Plovers and one Dunlin. Occasionally all of them took off at once, swooped around, and came back to rest again. Farther along, a small corner of solid land showed a Wood Duck nest with one or two juveniles and both parents—along with a visiting male Mallard!

Eventually, the group began to head back to the parking lot, passing some Brown-headed Cowbirds, a Blue-gray Gnatcatcher, and a Black-capped Chickadee along the way. Then suddenly a Pileated Woodpecker called, and everyone was rewarded by seeing the male first hop up a tree trunk, followed by landing on the ground on top of a fallen, rotting trunk. He then spent at least 20 minutes intermittently and efficiently hammering open holes and then gorging on termite larvae, while the group watched from a mere 15 feet away. This was one of many highlights of the trip.

Closer to the cars, the Marsh Wren(s) started murmuring again and we were finally rewarded with some brief glimpses—showing a definite contrast in size with our area’s largest woodpecker! Then a Green Heron flew past us and away. Happy with having seen so much, as well as having survived the weather, everyone headed back to the city with new experiences, new year-list birds, and, for a few, some lifers. All in all, we saw 61 species, as listed below.

Rockefeller State Park Preserve with Allan Welby, 5/27/2026

Registrar: Suzanne Zywicki
Participants: 10
Weather: Temperatures in the mid 60s – 70s °F, with light winds out of the west
Bird Species: 45

After rescheduling the trip twice due to rainy conditions, we were finally able to meet up with Allan Welby and several members of his local birding club to explore Rockefeller State Park Preserve. Soon after setting out from the Visitor Center, we encountered nest boxes being used by both Eastern Bluebirds and Tree Swallows spread out over the terrain and arranged in pairs. Allan explained that placing them this way increases the incidence of the two species peaceably sharing the area.

Soon after, we spotted the first of three Orchard Orioles seen on the trip, as well as a Baltimore Oriole. As we continued, the group got good looks at the first of eight Blue-winged Warblers we saw over the course of the day. All in all, we saw or heard a total of five warbler species, the most abundant of which was the Northern Yellow Warbler.

One of the target birds we were all hoping to see was a Pileated Woodpecker. Early on, we heard one drumming in the distance but were unable to locate it. Later in the walk, two birders again heard the sound and this time we were rewarded with good looks at two of the handsome woodpeckers moving from tree to tree.

As we made our way toward Swan Lake, we continued to see a mix of species, including five brilliantly orange male Baltimore Orioles sharing a tree, perhaps trying to impress the lone female across the trail. We also encountered both a male and female Rose-Breasted Grosbeak. At the lake, we saw a Great Blue Heron standing statue still, ready to strike, and an Eastern Kingbird flying back and forth across the water.

The walk provided a great introduction to the park for those who had not been there before and an enjoyable morning of birding for all.

Today was the first of several unusually hot days in Central Park, but despite the sudden and unpleasant change in weather, we enjoyed a productive day of birding. Fourteen warbler species were seen, including large numbers of Blackpoll Warblers and female warblers. The highlight of the day was a singing Summer Tanager in Strawberry Fields, a lifer for many participants.

We explored Inwood Park and were able to see many species of birds including good views of Bay-breasted Warblers and Blackpoll Warblers. Joe shared the interesting geologic and archaeological history of the park. Glacial formations including rock shelters, caves and glacial potholes were left by the retreating glaciers. The Lenape left shells, arrowheads and pottery, remnants of which can be still found in the park.

Sterling Forest State Park with David Spawn and Tod Winston, 5/16/2026

Registrar: Lisa Kroop
Participants: 14
Weather: 48–74°F; clear; calm to light breeze, 2–10 mph SW
Bird Species: 66

Many birds were singing as we gathered for our walk along the Sterling Forest power line cut. Among them were Common Yellowthroat, Northern Yellow Warbler, Blue-winged Warbler, Indigo Bunting, Ovenbird, American Redstart, Red-eyed Vireo, Tufted Titmouse, Prairie Warbler, Cerulean Warbler, and a blast from a Wild Turkey. We watched and listened to an energetically singing Prairie Warbler that was perched close above us on a crossbar of a power line tower. It was one of the first of many Prairie Warblers that we would hear along our walk. A Cerulean Warbler was also singing loudly, repeatedly. We headed south along the power line trail to try to locate it, following its song as it moved along the forest edge, though most birders, if not all, did not see it.

We turned around and headed into the woods, hearing Chestnut-sided Warblers, American Redstarts, and a Louisiana Waterthrush, and then walked out into the open and up the northern section of the power line cut. There were many more birds singing as we climbed the trail, and overhead we saw a Broad-winged Hawk and a Pileated Woodpecker that flew across the trail. As expected, there were several Blue-winged Warblers both heard singing and seen, but we didn’t find any Golden-winged Warblers or their hybrids.

Perhaps the highlight for many was the surprise appearance of a bobcat that crossed the path in front of some of the group as we were heading back to the cars. Many of those who missed seeing the bobcat crossing the path still managed to catch sight of it moving through the woods beyond us.

Many thanks to Tod and David for leading us on a wonderful walk in Sterling Forest.

Starr Saphir Memorial Walk in Central Park’s North Woods with Jeff Kimball, 5/15/2026

Registrar: Suzanne Zywicki
Participants: 18
Weather: Low 50s °F to mid 60s °F and partly cloudy with light wind
Bird Species: 46

Our group met our leader, Jeff Kimball, at the West 103rd Street entrance to Central Park. We headed up toward the Great Hill, stopping first at the Blowdown and then on to the “magic” Tulip Tree, where we were able to spot several warbler species, as well as an Indigo Bunting, Baltimore Orioles and numerous Cedar Waxwings.

After hearing reports of a vocalizing Bicknell’s Thrush (likely the same bird that had been in the area for several days) in the Loch, we decided to head down to try to find it. Along the way, we explored the lower parts of the Pool, where we saw several additional warbler species and paused to reminisce about Starr Saphir, the iconic birder and walk leader. Starr was well known to Jeff and to several members of our group. They shared their memories of her with those of us who did not have the privilege of meeting her. Inspired by the conversation, we then headed off to try to see the Bicknell’s which was happily in view when we arrived. We were also able to get good looks at a Wood Thrush in the area.

Our initial plan had been to continue to the Davis Center and the Meer; however the path was temporarily closed, so we decided to end our walk at the Loch. However, those of us heading west to leave the park stopped at the second cut-out along the way and were rewarded with nice views of a Hooded Warbler.
