Central Park with Ken Chaya, Lynne Hertzog and Kevin Sisco, 5/16/2023

Registrar: Michelle Zorzi
Participants: 52
Weather: Warm and sunny, light breeze, temperature upper 60s to low 80s
Bird Species: 78

On a warm spring morning, 52 eager birders gathered for an enjoyable morning of birding during
the peak of spring migration. A total of 22 species of warbler species were seen, including a male
Mourning Warbler sighted near Evodia Field by a few hardy birders who stayed out well into the
afternoon. A highlight for one group was finding a Black-billed Cuckoo by the Rustic Shelter,
where they enjoyed good views of this elusive bird. It was also a good day for Lincoln’s
Sparrows, as several were seen by the groups. Overall, it was a great day to be in the park, with
an impressive number of species seen.

Spring Migration at Governors Island with Todd Olson, 5/15/2023

Registrar: Mary Beth Kooper
Participants: 19
Weather: Clear skies, 57 – 66°F, Light breeze
Bird Species: 63

This was our first field trip led by Todd Olson, who works in conservation for the Wildlife Conservation Society at the Bronx Zoo. We had a wonderful morning, starting early with the 7:00 am ferry to the island, so it was still nice and quiet when we arrived and we were able to enjoy the bird songs and other vocalizations. We took a leisurely walk, starting around Fort Jay and meandering our way to the hills, and also visited the piers where the Common Terns and Herring Gulls have nested for a number of years. The walk produced a nice mix of migrants, in addition to other birds that nest on the island. We look forward to Todd
leading a similar walk in the Fall.

Liberty Loop and Wallkill National Wildlife Reservation, 5/15/2023

Registrar: Nick Dawson
Participants: 8
Weather: Sunny, low to mid 60s
Bird Species: 69

On a pleasant Sunday morning in late May, a small group of Linnaean Society birders journeyed up from New York City to walk the Liberty Loop trail, starting in New Jersey, moving into New York state, and then back to NJ. From the parking lot, we saw our first Sandhill Crane, a breeding bird at this spot that had evaded a group on the same trip the previous May. Later on, we were treated to more, including a female on her nest and a number of males competing for territory. The mixture of habitats—marsh surrounded by woodland and farm fields—offered up a nice variety of shorebirds, raptors, ducks, herons, woodpeckers, flycatchers, and migrant passerines. Other highlights of the morning, included a singing Marsh Wren, a Pileated Woodpecker, some Yellow-throated Vireos, and a Philadelphia Vireo—which, sadly, only some were able to get eyes on.

At the nearby Winding Waters Trail, also part of Wallkill River NWR, we were treated to nesting Eastern Bluebirds and Baltimore Orioles, plus Orchard Orioles on territory. Following a quick post-lunch stop at Owens Station Crossing and Wallkill River NWR’s headquarters, the birders who had stuck it out until mid-afternoon enjoyed a memorable final at Knapp’s View, where throngs of breeding Bobolinks can reliably be found mixed in with Red-winged Blackbirds and a few Eastern Meadowlarks.

Central Park, East Side, with Janet Wooten, 5/9/2023

Registrar: Janet Wooten
Participants: 11
Weather: Sunny and clear, 57F-64F, light breeze
Bird Species: 54, plus 1 hybrid

It was peak migration in Central Park on May 9th and the birds were everywhere, flying from tree to tree as they foraged for insects among the leaves. Many birds sang from the canopy level and were challenging to see but one in particular, the rare hybrid Brewster’s Warbler, caused great excitement. Birders listened patiently for its song and were delighted when it finally flew down low enough to give excellent views. While this Blue-winged Warbler/Golden-winged Warbler cross certainly made our day, we were equally dazzled by the stunning Summer Tanager, another rare visitor, with it’s all red plumage and large pale bill. It was a terrific morning of birding in the Ramble!

Central Park with Alan Drogin, Kevin Sisco, and Allan Welby, 5/9/2023

Registrar: Sally Weiner
Participants: 60
Weather: Sunny early, then clouding over, winds calm, temperature upper 50s to upper 60s
Bird Species: 74

In nearly ideal weather conditions, many birders—both locals and visitors from as far away as South Africa—joined together for a rewarding morning. Increasing numbers of warblers and other migrants overlapped with lingering winter birds to produce a rich variety. A Summer Tanager, perhaps the star of the walk, was well seen high above Azalea Pond and in the nearby area. Birding (for some!) extended into the early afternoon, yielding an impressive number of species.

Our group started out at 7:30am at the Central Park West and West 81st Street entrance to the Park, which was Starr’s meeting place. We went along Naturalists Walk, past Triplets Bridge to Hernshead and the Lake. We then walked by the Upper Lobe, went up to the Castle, along the south side of Turtle Pond, and through the Maintenance Meadow, where 2 Red Bats were flying around. A Great Horned Owl was perched in a tree in the Ramble. The Point, Swampy Pin Oak area, and Azalea Pond yielded several more species including Purple Finch, Northern Waterthrush, and Red-tailed Hawk. The walk ended at 12:00noon with 41 species, including 9 species of warbler.

Central Park-East Side with Janet Wooten, 5/2/2023

Registrar: Janet Wooten
Participants
: 7
Weather
: Intermittent rain throughout a cool morning with a southwesterly breeze
Bird Species: 30

Wet weather did not deter seven birders on the first Tuesday morning of May. We met at the Boat House and proceeded to search the Ramble and environs, the trees around the Castle, and Turtle Pond for migrating birds on their way to their breeding grounds. Despite periodic rain and cool temperatures, we managed to see six warblers, a Baltimore Oriole, and a Blue-headed Vireo. It was a challenging morning, but we prevailed with a final count of 30 species.
