White-whiskered Hermit

The white-whiskered hermit is about 13 cm (5.1 in) long. Males weigh 4 to 7 g (0.14 to 0.25 oz) and females 4 to 6.5 g (0.14 to 0.23 oz). This medium-sized hermit has a bronzy crown and iridescent bluish green upperparts. Its underparts are green to dark gray. The face has a black "mask" with a buffy supercilium and a white gular stripe. The male's bill is almost straight. The female has a shorter and gently decurved bill, shorter wings, more grayish underparts, and a longer tail than the male. Voice: The white-whiskered hermit's song is "a continuous series of rather harsh 'kree-u' notes". It also gives a series of "seek" notes while wagging its tail on a low perch at a lek.
