What type of hummingbird is this?

The tufted coquette 'Lophornis ornatus' is a tiny hummingbird that breeds in eastern Venezuela, Trinidad, Guiana, and northern Brazil. It is an uncommon but widespread species, and appears to be a local or seasonal migrant, although its movements are not well understood. A 'coquette' means a flirt, and to many birders, this species is indeed a tease. These small hummingbirds appear only infrequently at feeders and stay for only seconds at a time.

This small bird inhabits open country, gardens, and cultivation. The tufted coquette is 6.6 centimetres (2.6 in) long and weighs 2.3 grams (0.081 oz). The black-tipped red bill is short and straight. The male has a rufous head crest and a coppery green back with a whitish rump band that is prominent in flight. The forehead and underparts are green, and black-spotted rufous plumes project from the neck sides. The tail is golden rufous. The female lacks the crest and plumes. She has green upperparts (dorsal), except for the whitish tail band, and rufous underparts (ventral) that become much paler on the belly.

The female tufted coquette lays two eggs in a small cup nest made of plant down and placed on a branch. Tufted coquettes are tame and approachable. Their food is nectar, taken from a variety of flowers, and some small invertebrates. With their small size and steady flight, these birds often resemble a large bee as it moves from flower to flower.
