Night Flight Call of Yellow-rumped Warbler

Despite continuing strong winds, the pace of migration picked up during the last week of April. The largest movement of the week was the night of 25-26 April when near calm winds (< 10 km/hr) persisted throughout the night. An estimated 34 birds were recorded of which two-thirds were White-throated Sparrows. This species was by far the most common migrant during the week with an estimated 36 birds. The second most common bird of the week was Savannah Sparrow (13 estimated birds). The only other sparrow recorded was one Swamp Sparrow. Small numbers of Palm Warblers and Yellow-rumped Warblers were also detected. The first Greater Yellowlegs were noted on the night beginning on 30 April.
