Brown-crested Flycatcher
Myiarchus tyrannulus
The brown-crested flycatcher is 18 to 23 cm (7.1 to 9.1 in) long, with a general trend of larger to smaller from north to south. Subspecies M. t. magister is the largest taxon within the entire genus Myiarchus, weighing 36 to 54 g (1.3 to 1.9 oz). The other subspecies weigh 21 to 45 g (0.74 to 1.6 oz). The sexes have the same plumage. Adults of the subspecies M. t. magister and M. t. cooperi have a grayish brown crown whose feathers have darker shafts and form a bushy crest. Their upperparts are mostly light brownish gray to dark olive gray with often a rufous tinge on the uppertail coverts. Voice: The brown-crested flycatcher's dawn song varies somewhat among the subspecies but overall is "alternated renditions of isolated huits and complex phrases that are typically derived from combination of a whay-burg note with brief series of rapid huits".

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".
