Amazonian Elaenia

The Amazonian elaenia is 12 to 13 cm (4.7 to 5.1 in) long and weighs about 11 g (0.39 oz). Adult males have a dark gray crown with a partially concealed white stripe along its middle. They have a thin grayish white loral spot that continues around the eye and a grizzled whitish lower face. Their upperparts are blue-gray. Their wings are black with white edges on the inner flight feathers and white tips on the coverts; the last form two bars on the closed wing. Their tail is gray with white tips on the feathers. Their throat and underparts are mostly pale gray with a white belly. Voice: The Amazonian elaenia's two principal vocalizations are "a musical, descending, springy phrase: TSEE'SEE'see'see'see'sew" and a "somewhat sneezy tsee tsee TSEW-tsee-TSEW". They have also been written as "e-e-p-p-p-pepepepe ... pepepepupupupupu" and "ee-ee-ee-pit-chew, pit-chew, pee-chew" respectively.
