Short-tailed Woodstar

Myrmia micrura

Tiny2 gShrubland

The short-tailed woodstar is about 6 cm (2.4 in) long and weighs about 2.3 g (0.081 oz). It and the gorgeted woodstar (Chaetocercus heliodor) are the smallest birds in South America, though the little woodstar (C. bombus) is only slightly longer. It has a very short, slightly decurved, black bill. Both sexes have shining green upperparts. Males have a white stripe from the bill to below the eye. Their gorget is glittering violet and the breast white with dingy flanks. Their very short tail's central feathers are green and the rest blackish. Voice: The male short-tailed woodstar's song, given during the display flight, is "a sweet, high series of tititi notes interspersed with a high sweee." The species' call is a "thin tchi-tchi-tchi."
