Esta golondrina tiene un tamaño promedio de 13,5 cm (5 pulgadas) de largo y pesa unos 20 g. El pico es muy pequeño. La golondrina bicolor adulta tiene partes superiores de color verde iridiscentes, vientre blanco y una cola muy ligeramente bífida. La hembra generalmente tiene colores más opacos que el macho, más verde mientras que el macho es más azulado. El plumaje juvenil es gris marrón en la parte superior y puede tener una banda de pecho de color gris.
Altamente social fuera de la estación de cría, las golondrinas bicolor pueden formar bandadas de varios miles de aves cerca de los sitios de reproducción.Se estimó que los grupos cerca de Vacherie, Luisiana, tenían más de 1 millón de aves durante diciembre de 2009.
