Mt. Diablo: Mitchell Canyon Birds, Wildflowers & Butterflies 5/11/19

Today I went to Mitchell Canyon at Mt. Diablo with several friends from the Masterbirding program. Highlights included seeing Mt. Diablo Fairy Lantern which is still in bloom, seeing a good number of butterflies and  We had identified 33 bird species including Western Tanager, one of my favorites, 8 butterfly species and 19 wildflowers in bloom. It was a busy day for birders as we ran into two Golden Gate Audubon birding class field trips and a number of other birders on the trail as well. If you go stay on the trail/road as there is an abundance of Poison Oak in the area.

  1. Not Blue Dick, rather it is Uthuriel’s Spear Triteleia laxa.
