Bear Divide migration count. 8 April 2021. Light north/northwest wind (2-7 mph wind), temperatures ranging from 13° C at 0630 up to 22° C at 1030. Biggest day of the season, with a total of 2,532 individuals detected over the count period. Audubon’s Warblers constituted the highest percentage of migrants, with just over 1,000 individuals; very consistent stream of birds especially in the first 3 hours, with some groups exceeding 50 individuals at a time. Other high-count migrants were Lawrence’s Goldfinches, Black-throated Gray and Nashville Warblers, Cliff Swallows, & Western Kingbirds. Several birders coming and going throughout the morning, including the Occidental ornithology class; observer count is to the best of my recollection.
