The Lesser Elaenia (Elaenia chiriquensis) is a diminutive and often understated tyrant-flycatcher, a true gem of Neotropical avian diversity. Measuring approximately 12-14 cm (4.7-5.5 inches) in length and weighing a mere 10-15 grams, this small passerine sports an olive-gray dorsum contrasting with a paler, often yellowish-washed belly. Key field marks include two subtle whitish wing-bars, a faint but erectable crest that can be raised in excitement, and a delicate white eye-ring that gives ...
The Lesser Elaenia inhabits open woodlands, forest edges, clearings, and secondary growth, often favoring areas with scattered trees, scrub, and pastures. It is primarily found in lowland and foothill regions, generally occurring from sea level up to elevations of about 2000 meters.
The diet of the Lesser Elaenia primarily consists of insects, such as flies, beetles, and small wasps, which it captures in flight or gleans from foliage. It also supplements its insectivorous diet with a significant amount of small fruits and berries.

The Lesser Elaenia boasts an extensive and somewhat disjunct geographical distribution across the Neotropics, ranging from central Costa Rica and Panama southward through much of South America. Its breeding and resident range encompasses large portions of Colombia, Venezuela, the Guianas, Ecuador...
