Nashville Warbler

Nashville Warbler. Anza-Borrego Desert, California. April 27, 2014. Greg Gillson.

I'm continuing with birds photographed at Anza-Borrego Desert State Park the last weekend in April. This one is Nashville Warbler, which was found in a couple of places in the desert. They migrate at night and at dawn look for some place to feed quickly and then rest in the shade during the day, before taking off the next evening, if winds are favorable.

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.
