2nd Week of May – Beaver River, Yarmouth County, Nova Scotia

Spectrogram of Night Flight Call of Ovenbird

The return of rain, wind, and cool temperatures resulted in little nocturnal migration this week. Similar to one night in the previous week, the only notable migration occurred on the night of 11-12 May when strong winds blew out of the northwest at about 35 km/hr for most of the night. This would have pushed birds in northeastern Maine and southwest New Brunswick across the mouth of the Bay of Fundy to Beaver River. The most common species for the week was White-throated Sparrow. There was a smattering of mid-May warblers; Ovenbird, Blackburnian Warbler, Common Yellowthroat, Black-throated Green Warbler, Black-and-white Warbler, and Northern Parula.
