Trip Report: Humboldt Park 2017 September 23

Black-throated Green Warbler

A group of 15 birders met at the Field House in Humboldt Park with a brilliantly blue sky and summer-like temperatures. Our walk lasted about three hours and took us down the Prairie River and back up on the other side to the lagoon, and back to the Field House. We saw a total of 42 species. Some of the highlights were at least one juvenile Cooper’s Hawk, two young Red-tailed Hawks, a Philadelphia Vireo, both Swainson’s and Gray-cheeked Thrushes—sometimes in close vicinity to each other, making for good comparisons. We ended-up seeing 12 species of wood warblers. Many of us would agree that the three different—age and sex—Black-throated Green Warblers stole the show. Sparrows were sparse, but a Lincoln’s Sparrow was nicely visible. A special thank you to COS for organizing the trip and to Andrew Aldrich for his assistance.
