Steely-vented hummingbird

The steely-vented hummingbird (Saucerottia saucerottei) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Colombia and Venezuela.

The steely-vented hummingbird is 8 to 11 cm (3.1 to 4.3 in) long and weighs about 4.4 to 5.0 g (0.16 to 0.18 oz). Both sexes of all subspecies have a black bill with a pinkish or reddish base to the mandible. Adult males of the nominate subspecies have golden-green upperparts with blue-black uppertail coverts. Their tail is also blue-black. Their underparts are dark glittering golden-green with greenish to steel blue undertail coverts. Adult females have some white on their throat feathers and grayish-brown undertail coverts. Immature birds somewhat resemble the female but are overall duller and have a partly dark gray throat, a grayish brown belly, and brownish edges to the back and rump feathers.

The other two subspecies differ little from the nominate. S. s. warscewiczi is somewhat smaller and has a purplish to bluish tinge to the uppertail coverts. S. s. braccata has purplish tips on the rump feathers and violet-blue to bluish uppertail coverts.
