Strange-tailed Tyrant

The strange-tailed tyrant is about 20 cm (7.9 in) long excluding the male's 10 cm (3.9 in) tail. Adult males in breeding plumage have a mostly black face with white lores and a white supercilium. Their back is mostly black with white scapulars and a gray rump. Their wings are black with white tips on the coverts and white edges on the flight feathers. Their tail is black and very long with a highly modified outer pair of feathers. Voice: As of May 2025 xeno-canto had three recordings of strange-tailed tyrant vocalizations; the Cornell Lab's Macaulay Library had five others. The only described call is by females when they and young are near each other; it is a "soft and weak whistled thee-uu, schee-uu" whose last note descends.
