CEIBA Research, Guyana (Image 13) Tufted Coquette (Lophornis ornatus), a tiny hummingbird found in eastern Venezuela, Trinidad, Guyana and northern Brazil that lives in open country, gardens and cultivation. They grow to only 6.6 centimeters long and weigh about 2.3 grams. Males have a rufous head crest and a coppery green back with a whitish rump band that is easily seen 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 has no crest or plume, but has green upperparts, a whitish tail band, and rufous underparts which become paler on the belly. The tail is mostly bronze green with a dusky band and whitish tips on the feathers. Young males look like the female, but the throat is whitish with fine dark spotting. They have a black-tipped red bill that is short and straight. Female Tufted Coquettes will lay two eggs in a small cup nest made of plant down and placed on a branch. These birds are not shy, and can be approached. They favor nectar from a variety of flowers and some small invertebrates. They make a light "chik" sound while feeding.
