During this early morning's walk in the woods, while shuffling through last year's rustling leaves with the dogs, a clear warble ending with a rising buzz announced a Cerulean Warbler. With the aid of leafless trees, I easily watched him foraging in the high canopy branches, jabbering away all the time. The only earlier date here for a Cerulean was in 2012, May 7th. The arrival dates for the last 7 years are well bunched, from May 7th to the 13th. Warblers and vireos seen and heard were: Cerulean Warbler Black-and-white Warbler Black-throated Green Warbler Black-throated Blue Warbler American Redstart Blackburnian Warbler Pine Warbler Chestnut-sided Warbler Yellow-rumped Warbler Nashville Warbler Common Yellowthroat Ovenbird Blue-headed Vireo Yellow-throated Vireo (A pair has been around for at least the last week. This morning they worked their way down from the canopy until on a branch facing the sun and me, only a dozen feet away. Gorgeous birds in the brilliant light of the just rising sun.!) Ian
