Tyrant-flycatchers (Tyrannidae)

Rusty-margined Flycatcher (Myiozetetes cayanensis) - HBW 9, p. 406

French: Tyran de Cayenne German: Rostschwingen-Maskentyrann Spanish: Bienteveo Alicastaño

Taxonomy: [Muscicapa] cayanensis Linnaeus, 1766, Cayenne.
Morphological and behavioural evidence suggests genus most closely related to Legatus; nesting behaviour links with Pitangus. Molecular data indicate strong support for a clade consisting of present species and M. similis as sister-group to one formed by M. granadensis and M. luteiventris. South American races require closer scrutinty; birds from E Panama described as additional race, harterti, on basis of smaller size, but subsequently considered inseparable from hellmayri. Four subspecies currently recognized.
