Snethlage’s Tody-Tyrant

Snethlage's tody-tyrant (Hemitriccus minor) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Venezuela, and possibly Peru. == Taxonomy and systematics == Snethlage's tody-tyrant was originally described as a subspecies, Euscarthmus zosterops minor, of what is now the white-eyed tody-tyrant (Hemitriccus zosterops). It was later accepted as a full species. For a time in the mid-twentieth century several authors placed it in genus Snethlagea, which was later merged into Hemitriccus. Major taxonomic systems recognize three subspecies of Snethlage's tody-tyrant, the nominate H. m. minor (Snethlage, 1907), H. m. snethlageae (Emil Heinrich Snethlage, 1937), and H. m. pallens (Todd, 1925). One of them, the Clements taxonomy, in addition lists "Hemitriccus minor [undescribed form]" as potentially a new subspecies from within one of the others. The species' English name and the subspecific epithet of H. m. snethlageae commemorate the German-born Brazilian naturalist and ornithologist Emilie Snethlage (1868-1929). == Description == Snethlage's tody-tyrant is about 10 cm (3.9 in) long and weighs 7 to 7.9 g (0.25 to 0.28 oz). The sexes have similar plumage. Adults of the nominate subspecies have an olive-green crown with a short bushy crest. Their face, back, and rump…
