Hook-billed Hermit
Glaucis dohrnii
The hook-billed hermit (Glaucis dohrnii) is an endangered species of hummingbird in the family Trochilidae. It is found in humid forests in eastern Brazil, with recent records from the states of Espírito Santo and Bahia only. It resembles the far commoner rufous-breasted hermit, but has a straighter bill and lacks rufous in the tail. It is threatened by habitat loss and changing migration patterns.

Description
The hook-billed hermit is 12 to 13 cm (4.7 to 5.1 in) long. Males weigh 6 to 9 g (0.21 to 0.32 oz) and females 5.5 to 7 g (0.19 to 0.25 oz). Its upperparts are greenish bronze and the underparts cinnamon. The face has a white supercilium and "moustache" and is otherwise dusky. The tail is metallic bronze with white-tipped outer feathers. Its bill is nearly straight. The sexes have essentially the same plumage though the female's underparts are somewhat paler than the male's.
Range & habitat
The hook-billed hermit is found only at a few sites in the southeastern Brazilian states of Bahia and Espírito Santo in Neotropical realm forest climates. It probably formerly occurred in Minas Gerais and possibly Rio de Janeiro states, though in the latter it is known only from trade skins that might have originated elsewhere. It inhabits the understory of inland primary and littoral forests, usually along streams. It favors areas with abundant Heliconia plants. In elevation it ranges from sea level to 500 m (1,600 ft).

What it does
Like other hermit hummingbirds, the hook-billed hermit is a "trap-line" feeder, visiting a circuit of flowering plants. It feeds on nectar at Heliconia and other plants and also on small arthropods, but details are lacking.
