||I was lucky enough to get these pictures of this bird, the first of its species ever recorded in Santa Clara County, without knowing what I was doing. The bird was in shade and I saw it only as a dark outline against a bright sky when I photographed it. Later when I viewed the images on my computer, after compensating for the underexposure, the bird showed marks inconsistent with the expected Warlbling Vireo -- dark lores and crown, a short bill, and extensive yellow underneath. I posted the pictures with a query about the identification, and poor as they are, local experts found them good enough to call the bird a Philadelphia Vireo. Unfortunately the best efforts of local birders were not enough to relocate this great local rarity.
