Dusky-capped Flycatcher
Myiarchus tuberculifer
The dusky-capped flycatcher is 16 to 18.5 cm (6.3 to 7.3 in) long and weighs 14 to 27 g (0.49 to 0.95 oz). The sexes have the same plumage. Adults of the nominate subspecies M. t. tuberculifer have a sooty brown crown and face; the crown feathers form a slight crest. Their upperparts are mostly dark greenish olive-brown with browner uppertail coverts. Their wings are mostly dusky with thin dull white edges on the secondaries and thin buffy-white edges on the inner primaries. Their greater and median wing coverts have buffy brown edges. Their tail is dark grayish brown. Voice: The dusky-capped flycatcher's vocalizations vary across its range. In Mexico its dawn song "consists of a long series of "sentences" made up of 2 or 3 elements". In much of Central America it is "a short, sharply whistled whit, a long drawn, plaintive, whistled wheeeu, and an emphatic whistle cut short". In much of South America it is "plaintive whistles alternated with huit notes".

Great Crested Flycatcher
Myiarchus crinitus
Adult great crested flycatchers usually measure between 17–21 cm (6.7–8.3 in) in length with a wingspan of around 34 cm (13 in). This bird usually weighs between 27–40 g (0.95–1.41 oz). There is no sexual dimorphism. All adults are brownish on the upperparts with yellow underparts; they have a long rusty brown tail and a bushy crest. Their throat and breast are grey. Males will sing a three-part song composed of two short whistles: a wheerreep followed by a higher-pitched whee, and a soft low churr.
