Re: Clay Colored Sparrows, Nashville Warbler, Blackpoll Warbler, Chestnut-Sided Warbler

Hi David,

Looks like a really fun day. The photo you posted from Ft Mason on your eBird list labeled “Clay-colored Sparrow” actually looks like a Chipping Sparrow to my eye. The malar looks quite dark, the auricular is dark, and it looks like this bird has dark lores from what I can tell, all of which is better for Chipping Sparrow. Unfortunately, the photo quality is quite poor. Awesome finds otherwise!

Started the morning at Crissy Field just before dawn, and had a CLAY COLORED SPARROW in with WHITE-CROWNED SPARROWS on the field. At Fort Mason, one of the first birds I saw was also a CLAY-COLORED SPARROW, on the lawn in front of the garden. Lots of migrants on the move. While I was taking pictures, Juan Garcia had a BLACKPOLL WARBLER in the Eucalyptus trees. More WESTERN TANAGERS than I've seen on any one day (30+), at least 18 YELLOW WARBLERS, 3 WARBLING VIREOS, 1 BLACK-HEADED GROSBEAK, 3 PACIFIC-SLOPE (WESTERN) FLYCATCHERS, and a continuing NASHVILLE WARBLER. Later I was able to see the CHESTNUT-SIDED WARBLER that Jack Hayden found in Sue Bierman Park.
