Songbird Migration Is On!

Migration is beginning to pick up steam in the bosque. Among warblers, Yellow Warblers are currently moving through in the largest numbers, with smaller numbers of MacGillivray’s Warblers and Virginia’s Warblers also popping up. Wilson’s Warblers are just starting to trickle into the bosque, and we have also recorded Black-throated Gray Warbler and Orange-crowned Warbler over the past week. Other migrants currently moving through include Western Tanager, Warbling Vireo, Rufous Hummingbird, Broad-tailed Hummingbird, Calliope Hummingbird, and Gray Flycatcher. Other species of note include Lark Sparrow and Chipping Sparrow, both of which are moving around in large numbers, the occasional Red-breasted Nuthatch, and increasing numbers of Bullock’s Oriole and Lazuli Bunting
