Fall Migration at Randall’s Island with Andrew Farnsworth, 9/21/2022

Registrar: Mary Beth Kooper
Participants: 8
Weather: 64 – 73°F, light NW wind
Bird Species: 43

We were very fortunate to have Andrew Farnsworth lead this walk for our organization. Andrew directs the BirdCast Project, a collaboration between ornithologists and computer scientists to forecast bird migration. Our field trip got off to an exciting start when participant Junko Suzuki found a first for the county—a Buff-breasted Sandpiper—before the trip even began! We were treated to great views of this special visitor to the county, and for several in our group, it was a life bird. While we were watching it, a Peregrine Falcon flew over, and the sandpiper froze still on the grass. Andrew explained that this was typical behavior for this species: freezing in place when it senses danger, rather than flying off.

After some time spent examining and learning about the Buff-breasted Sandpiper, we started exploring the northeastern end of the island. We soon found some Savannah Sparrows, and Andrew helped us focus on certain features (short tail and crisp breast streaking) in order to quickly differentiate this sparrow from the more commonly seen Song Sparrow (longer tail, coarser breast streaking).

After covering the northeastern part of the island we headed west, walking down to Little Hell Gate Marsh and then up to the north side of the Freshwater Wetlands. Finally, we walked back to the fields in the northeast to end the trip, after seeing a nice variety of species and learning a great deal from our expert leader.
