About the Double-banded Pygmy-Tyrant

The double-banded pygmy tyrant (Lophotriccus vitiosus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, and Suriname. The double-banded pygmy tyrant was originally described in 1921 as Cometornis vitiosus. The authors erected genus Cometornis for it and some other newly described species and subspecies. They soon recognized that by the principle of priority Cometornis had to be replaced by Lophotriccus.

The double-banded pygmy tyrant has these four subspecies: L. v. affinis Zimmer, JT, 1940 L. v. guianensis Zimmer, JT, 1940 L. v. vitiosus (Bangs & Penard, TE, 1921) L. v. congener Todd, 1925 Subspecies L. v. congener was originally described as a full species and was treated that way by some authors until the mid-twentieth century. In addition, several authors have suggested that genus Lophotriccus should be merged into genus Hemitriccus.

The double-banded pygmy tyrant is about 10 cm (3.9 in) long and weighs 6 to 8.5 g (0.21 to 0.30 oz). It has long crown feathers that form a crest and that it occasionally erects and fans; the feathers extend... Wikipedia →
