This morning, while listening to multiple Mourning and Chestnut-sided Warblers (among an overwhelming chorus of crooners) on Blue Hill Trail in Sherburne Refuge, a probable Hooded Warbler broke in with 3-4 lines of song.
I say "probable" because the song was a bit variant from "wheety, wheety, wheety-o" - took a bit of time to work through my consciousness (I only hear this bird once a year or so) - shut down when I pished - and never made a physical appearance. The song did come from the area where a single male Hooded has hung out two of the last four years - left side of the trail, 100 feet or so past the first left turn, about 10 minutes in as the birder walks. Sometimes I hate "probables".... Al Schirmacher Princeton, MN Mille Lacs & Sherburne Counties
