Sooty-capped Hermit

The sooty-capped hermit is about 14 to 15 cm (5.5 to 5.9 in) long. Males weigh 4.5 to 6 g (0.16 to 0.21 oz) and females 4 to 5 g (0.14 to 0.18 oz). They are mostly grayish brown above with a rufous rump and uppertail coverts. The next-to-inner tail feathers are longer than the others and all have white tips. Their underparts are gray. The face has a black "mask" with a white supercilium and gular stripe. The subspecies differ slightly in the intensity of the breast and uppertail covert colors and the size of the gular stripe. What was once thought to be a separate species P. Voice: The sooty-capped hermit's song is "a continuously repeated phrase consisting of 2–3 high notes followed by 2–3 somewhat lower ones, e.g. 'tsee-tsee-tsee-sew-sew....tsee-tsee-tsee-sew-sew...'." The male sings from a perch at a lek while wagging its tail. It also makes a "rather monotonous 'tseet'" call.
