White-crested elaenia
The white-crested elaenia (''Elaenia albiceps'') is a species of bird in the Tyrannidae family, the tyrant flycatchers. It has several subspecies breeding across southern and western parts of South America. Southern birds migrate north in winter.
Its natural habitats are temperate forests, subtropical or tropical moist montane forests, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.
==Description==
The white-crested elaenia easily is recognizable as an elaenia by the combination of drab plumage (primarily dull green above, and whitish below); wings with conspicuous wing bars (pale tips to the greater and median wing coverts); slightly crested appearance, with a semi-concealed white center to the crown; and upright posture. small-billed elaenia, lesser elaenia and sierran elaenia cannot always be distinguished in the field. Length in this species is 13.5–15 cm (5.3–6 in) and weight is 12.5-24.3 grams, with an average of 16.3 grams.
