观察细节
I was watching a flock of Harris's and White-crowned Sparrows when I saw a small pale tan sparrow with a very short tail weakly fly up from the weeds by the edge of the wheat field and drop into a small patch of tall native prairie grass near the bridge. My first thought was that it was obviously a Le Conte's, but then as I approached it flew up and perched in a young American Elm providing great looks through binoculars and a few pictures before flying again, after which I couldn't find it. I had several minutes of looking at it through binoculars in which I really tried to find the markings of Le Conte's but simply couldn't. The breast and sides were clean buffy with absolutely no streaking, and no dark lateral throat-stripe. Also noted lack of purplish nape(gray instead), gray lores(yellowish instead) and auriculars, white edged tertials and bold stripes on back. Also saw that this bird had a bold complete white eye-ring, large tanish bill(not gray), two dark auricular spots, white median crown stripe and overall non-contrasting markings. I zoomed in and examined each one of these photos and am very confident of the identity of this late migrant.
