|Nashville Warbler. Anza-Borrego Desert, California. April 27, 2014. Greg Gillson.|
I visited an area near the Borrego land fill. It was a barren patch of Mojave Desert with sand interspersed by well-spaced creosote bushes. I was looking for LeConte's Thrasher. It was birdless. In a mile of walking I ended up with one Tree Swallow(!), one Say's Phoebe, and one Black-throated Gray Wabler!
Migrant warblers tallied during the day:
Orange-crowned Warbler 1
Nashville Warbler 6
MacGillivray's Warbler 1
Wilson's Warbler 4
Black-throated Gray Warbler 3
Townsend's Warbler 3
And add likely summer resident Yellow Warbler 4+ and Common Yellowthroat 3.
