  47. Townsend's x Hermit Warbler (hybrid)

    Number observed:  1

    Details

    Bird seen foraging briefly in eucalyptus on the golf course before it flew down into goldenbush near me, where I could immediately see that the bird was intermediate between Townsend's and Hermit. Unfortunately, before I could snap a photo at eye-level, an OCWA chased it up into a willow tree in bad light. There, I could see further that the bird appeared to be a female that was intermediate in several traits between the two species. Amazingly, it landed on a branch in the open and remained there for perhaps 20 seconds, allowing for several photos using different setting to try and mitigate the backlighting. A few came out pretty well. The bird was a female, given the lack of yellow on the underparts..
