About the Yellow Tyrannulet

The yellow tyrannulet (Capsiempis flaveola) is a small passerine bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Costa Rica, Nicaragua, Panama, and in every mainland South American country except Chile and Uruguay.

The yellow tyrannulet was originally described in 1823 as Muscicapa flaveola and in 1859 moved to the newly created genus Capsiempis. In the 1970s that genus was merged into Phylloscartes but by 1990 it had been resurrected. The yellow tyrannulet is the only member of genus Capsiempis.

The yellow tyrannulet has these five subspecies: C. f. semiflava (Lawrence, 1865) C. f. cerula Wetmore, 1939 C. f. leucophrys Berlepsch, 1907 C. f. magnirostris Hartert, EJO, 1898 C. f. flaveola (Lichtenstein, MHC, 1823) The yellow tyrannulet is 10 to 11.5 cm (3.9 to 4.5 in) long and weighs about 8 grams (0.28 oz). The sexes have the same plumage. Adults of the nominate subspecies C. f. flaveola have a dark yellowish olive crown with a somewhat bushy crest. They have a bright yellow supercilium, a bright yellow partial eye ring, and a dark line through the eye on an otherwise yellowish face. Their upperparts... Wikipedia →
