White-throated spadebill
The white-throated spadebill (''Platyrinchus mystaceus'') is a tiny passerine bird in the tyrant flycatcher family. It lives in the tropical Americas.
==Description==
The adult white-throated spadebill is 3.8 in (9.7 cm) long, weighs 0.33 oz (9.3 g), and has large eyes and a very short tail. The large head is distinctively marked, with a long yellowish supercilium, blackish ear coverts, yellow eyering, and a black stripe down each side of the neck. The crown has a concealed yellow crest, which is erected as a fan by the singing male. The upperparts are dark olive brown, and the underparts are buff apart from the white throat. The bill is black above and brown below, and is very broad and flat, hence the English and scientific names "spadebill" and ''Platyrinchus''.
Sexes are similar, other than the female having a smaller crown patch, but young birds are brighter and ruddier above, lack the crown patch, and have a grey throat and breast shading to a whitish belly. They are not particularly vocal but have a sharp ''chweet'' call.
The subspecies ''Platyrinchus mystaceus insularis'' occurs only in Trinidad, Tobago and in Venezuela, other forms differing in the brightness of the underparts or the crown colour. The taxonomy of this species is uncertain, with some dubious subspecies, but also the possibility that what is usually treated as the white-throated spadebill consists of more than one species.
