ID Notes:
The photos show the yellow undertail coverts of Lesser rather than white on American. Also the upperparts are more olive green and wing bars are slightly reduced (and have the white mark at the base of the outer primaries).

The vocalizations recorded are also distinctive for Lesser Goldfinch, including some of the descending clear calls that they frequently make. The vocalizations are actually often the best way to detect a Lesser Goldfinch once you become familiar with the calls they make!
