From Jonathan Center:
Seven participants attended a Brookline Bird Club walk on May 5th to Oxbow Natl. Wildlife Refuge, Harvard with an extension afterwards to Bolton Flats and Pine Hill Road Grasslands in Lancaster. 57 species were totaled. Weather was clear starting at 40 degrees (or possibly lower by a few degrees) at 7:00am and ending at around 64 degrees by 3:00pm.
Nice views were had of a Yellow-throated Vireo, Great Crested Flycatchers, two Common Ravens souring overhead, several Blue-gray Gnatcatchers, and Rose-breasted Grosbeaks at Oxbow NWR.
Multiple Yellow Warblers were seen and heard at Bolton Flats. Also a single Virginia Rail was heard and a couple of Rough-winged Swallows were observed darting around and disappearing in a possible nest hole in a bank of the Nashua River.
The trip concluded at the Pine Hill Rd. Grasslands in Lancaster with excellent views of Vesper Sparrow and singing Prairie Warblers.
