"Astragalinus tristis. American Goldfinch. Yellow-bird. Thistle-bird. In summer: Rich yellow, changing to whitish on the tail-coverts; a black patch on the crown; wings black, ore or less edged with white; lesser wing-coverts white or yellow; greater coverts tipped with white; tail black, every feather with a white spot; bill and feet flesh-colored. In September, the black cap disappears; the general plumage changes to a pale flaxen-brown above and whitey-brown below, with traces of the yellow, especially about the head; wings and tail much as in summer; sexes then much alike: this continues until the following April or May." Elliot Coues, 1884
