A difficult day to observe at Bluff Point this morning. Dark skies and breezy conditions made identifying birds flying out even more difficult than usually is the case. Conservatively estimating roughly 350 warlers leaving the hot corner. 17 species identified and counting. Highlights included a Mourning Warbler, two or more Philadelphia Vireos, and the first Ruby-crowned Kinglets of the season. Movement still very heavily dominated by American Redstarts, this indicates many more warblers still to come under the right conditions. Dave Provencher Preston
