Black-throated Green Warbler - 1 of 10 around the Lookout Tower at Quabbin Park.
Had a good morning at Quabbin Park concentrating on Winsor Dam from the HQ buildings, the Lookout Tower area and a brief scan over Goodnough Dike. Migration was much in evidence throughout the morning (07:35hrs - 11:30 hrs) with highlights including a sudden and unexpected arrival of birds on Winsor Dam wall, a busy and rather intense feeding flock around the base of the Lookout Tower, and a small but decent collection of migrant waterfowl at Goodnough Dike. Four American River Otters at the latter spot came as a complete surprise, a species which I don't recall seeing anywhere in the Quabbin in previous years.
