Long-tailed hermit

The long-tailed hermit (Phaethornis superciliosus) is a large hummingbird that is a resident breeder in Venezuela, the Guianas, and north-eastern Brazil. This species was formerly referred to as the eastern long-tailed hermit.

The adult long-tailed hermit is mainly dull brownish green above with a buff-tinged rump. It has a dark mask through the eye, bordered above and below with whitish-buff stripes. The underparts are pale greyish-buff in colour. The sexes are similar, although the female is slightly smaller. It is the largest of hermit hummingbirds, with a length of around 15 cm (5.9 in) and a body mass of 6.3 g (0.22 oz).

During the breeding season, male long-tailed hermits sing in communal leks of up to several dozen birds, and also wiggle their long tails in display. Competitive lek singing can occupy half of the daylight hours, the purpose of course being to attract females. The female selects the best lek singer to mate with. The song consists of sharp tsuk sounds.

The female long-tailed hermit is solely responsible for nest construction, incubation and feeding the young. She lays two white eggs in a conical nest of fibres and cobwebs suspended under a large Heliconia or banana leaf.
