Panama Tyrannulet

The Panama tyrannulet is 10 to 11 cm (3.9 to 4.3 in) long; one female weighed 8.8 g (0.31 oz). The sexes have the same plumage. Adults have grayish white lores and a white eye-ring. A dusky band through the eye continues around the yellowish ear coverts. Their upperparts are olive green with a slighter grayer crown. Their wings are dusky with yellowish olive green to yellower edges on the flight feathers. Their wing coverts are dusky with large pale yellow tips that form two wing bars. Their tail is grayish brown with pale olive green edges to the feathers. Voice: As of late 2024 xeno-canto had only six recordings of Panama tyrannulet vocalizations and the Cornell Lab of Ornithology's Macaulay Library had nine. What might be its call is "a very rapid dree-di-di-dít". What might be the same vocalization is described as a "short, high pweet! or ptwit!, sometimes followed by short chatter of high, thin notes."
