Dusky Chlorospingus
Chlorospingus semifuscus
The dusky chlorospingus is 14 to 15 cm (5.5 to 5.9 in) long and weighs 17 to 23 g (0.60 to 0.81 oz). The sexes have the same plumage. Adults of the nominate subspecies have a dark gray crown and face with sometimes a tiny white spot behind the eye. Their nape, upperparts, and tail are dark olive. Their flight feathers are dusky with yellowish olive edges except on the tertials, which are mostly dark olive. Their throat and underparts are mostly brownish gray. Their breast, flanks, and undertail coverts have an olive tinge. Voice: The dusky chlorospingus' song is "a series of almost hummingbird-like, high-pitched notes that gradually speed up and gain strength, becoming quite 'spanking' before ending in a dry sputter". It is most often heard at dawn and sometimes in late afternoon. The species' calls are "an extremely high-pitched chip, often repeated, and a thin penetrating trill".

Their flight feathers are dusky with olive-yellow edges. Their throat is whitish with many, though inconspicuous, black specks. Voice: The sooty-capped chlorospingus sings "a thin squeaky twittering". The song has been written as "see-chur see-chur see-chur see see see-chur" and "sit-sit swíee-d-d-d-d-d-d sit-a-wit". Its calls include "high, thin, lisping tsit notes followed by t-z-z-z-z-z-zit, chat-t-t-t-, zwee-zwee-zwee... and so on".
