观察细节
Fairly young juv. Perched on wire near Purple Martin, Cliff Swallow, Barn swallow group. Notably smaller than adjacent Cliff Swallow. Warm breasted with clear throat and upper breast. Notably strong capped effect/ pale nape. Seen well from below. Although pic seems to show a faint smudge on one feather of the upper tier of undertail coverts, the marks were extremely faint/ missing, except on lower tier of undertail coverts, in near side by side comparison with juv Cliff.
