СКАЧАТЬ sides pale greyish-blue. Female similar but paler; the loral band wanting; throat, fore neck, and breast yellow, without the black lunule.

      Although the bill of this species is much attenuated, it is not essentially different in form from that of S. Blackburniæ, and others of this genus; the wings are similar to those of the rest, and there seems no reason for setting it apart to form a genus, as has been done by Bonaparte.

      Male, 41/6, 61/2.

      From Texas, generally distributed. Exceedingly abundant. Migratory.
