As Carole Winslow found in western PA, lots of birds in Berks & Schuylkill have been moving on not much of a north wind during the last few nights. South Lookout at Hawk Mt. Sanctuary is a good place to stand in the hour before sunrise listening for nocturnal migrants coming down from their red eye night flights. This morning I counted over 1100 calls, mostly of Swainson's Thrush. I was a little surprised to hear only 4 Gray-cheeked Thrush calls in that large crowd. Warbler counts at North Lookout have been good in the last few days. This morning's standout in that group was a remarkable count of 203 Cape May Warblers, plus lots of Tennessee, Black-throated Green and Scarlet Tanager. When that many birds pass, darting in and out of foliage, in such a short time, I feel as though I'm looking through a kaleidoscope, with each turn of the glass revealing a new pattern of colorful fragments. The list is below.
