About the Amazonian Tyrannulet

The Amazonian inezia, or Amazonian tyrannulet, (Inezia subflava) is a species of passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Colombia, and Venezuela. The Amazonian inezia was originally described as Serpophaga subflava. Some early twentieth century authors later placed it in genus Capsiempis.

The Amazonian inezia has two subspecies, the nominate I. s. subflava (Sclater, PL & Salvin, 1873) and I. s. obscura (Zimmer, JT, 1939). The two subspecies of what is now I. caudata were previously considered subspecies of I. subflava all under the name pale-tipped inezia. They were separated based on differences in their plumage and vocalizations that were detailed in a study published in 2000. Confusingly, the English name pale-tipped inezia (or tyrannulet) that originally applied to the four-subspecies I. subflava was assigned to I. caudata.

The Amazonian inezia is about 12 cm (4.7 in) long and weighs 7 to 8 g (0.25 to 0.28 oz). The sexes have the same plumage. Adults of the nominate subspecies have a brownish olive to olive crown with a duskier lower edge. Their face is mostly olive to yellowish... Wikipedia →
