Needle-billed Hermit

The needle-billed hermit is 12 to 13 cm (4.7 to 5.1 in) long. Males weigh 4 to 6 g (0.14 to 0.21 oz) and females 4 to 5.5 g (0.14 to 0.19 oz). It is one of the few hermit hummingbirds with a nearly straight bill. Its upperparts are dark bronzy green with a dull rufous rump. The tail is mostly dark green. The innermost pair of tail feathers are longer than the others and have long white tips; the others have broad buffy rufous tips. The face has a black "mask" bordered with narrow pale streaks. The underparts are orange.

The needle-billed hermit is found in eastern Peru, northern Bolivia, and western Brazil south of the Amazon River as far east as the Tapajós River. It inhabits the understory of lowland rainforest. It is mostly found in terra firme forest but also occurs in várzea forest, bamboo thickets, and plantations. In elevation it ranges only as high as 325 m (1,100 ft).

The needle-billed hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of a wide variety of flowering plants for nectar. It also consumes small arthropods.
