As is usually the case, fairly few passerines were seen or heard during the windy, blustery frontal passage of the last few days, but last night's cold, calm conditions apparently got birds moving. (My car thermometer registered a nearly frosty 34F in the valley below Hawk Mt. at 5:45 a.m.) I heard about 400 nocturnal flight calls at South Lookout from 6-6:30 a.m., mostly of Swainson's Thrush. At North Lookout, there was another big movement of mostly boreal warblers and Blue-headed Vireos from about 7-9 a.m. The list is below. The nearly windless conditions killed the raptor flight, of course.
