1st Week of April 2019 – Beaver River, Yarmouth County, NS

Spectrogram of Song Sparrow Flight call recorded on 7 April 2019

Nocturnal migration monitoring began on the evening of April 1st. High winds for the first five days of the week resulted in few call detections except for small numbers of Canada Geese that were either local breeding birds or a stragglers that had not yet headed north. With the diminution of winds on the nights beginning on April 6 and 7, there was a small passerine migration consisting of Song Sparrows and a Fox Sparrow. An Eastern Phoebe was flitting near the monitoring station after dawn on both days. Other nocturnal calls on those nights included Mallard/American Black Duck, Green-winged Teal, and a Great Blue Heron.
