观察细节
Silent grayish empid with short bill and modest eye-ring. Observed at 37.623268, -121.745971 while looking for previously reported Calliope Hummingbird. Reporting this bird as a Dusky (as opposed to Hammond's) because of 1) long apparent length of tail relative to short primary extension (extension also short relative to tertials), 2) roundish head with minimal peaking at back, 3) grayish head/nape contrasting subtly with greenish back, and 4) observed in low thicket environment. Tail flicking behavior not noted. This is a tough call with less than ideal pics, but will consider it a "learning" experience. Will happily be corrected. Pics 1 and 2 DBangs, Pics 3-6 DKadra.
