Acrochordopus zeledoni
The White-fronted Tyrannulet, *Acrochordopus zeledoni*, is a diminutive and highly active songbird belonging to the tyrant-flycatcher family (Tyrannidae). Measuring approximately 10-11 cm (4-4.3 inches) in length and weighing a mere 6-8 grams, it is characterized by its olive-green upperparts, a striking white forehead contrasting with a dark eye-line, and a prominent white supercilium that extends behind the eye. Its underparts are predominantly whitish, often with a faint yellowish wash on ...
Found primarily in humid montane cloud forests and forest edges, typically at elevations ranging from 900 to 2,500 meters (3,000-8,200 feet) above sea level.
Feeds almost exclusively on small insects and spiders, which it gleans from foliage and twigs or occasionally captures in short aerial sallies.
This active, diurnal tyrannulet is almost constantly in motion, flitting rapidly through the mid-story and sub-canopy of its dense forest habitat. It employs a 'hover-glean' foraging strategy, often hovering momentarily to pluck insects from the undersides of leaves and twigs, but also makes shor...
The White-fronted Tyrannulet exhibits a disjunct distribution across humid montane regions of Central and South America. In Central America, it is found in the highlands of Costa Rica and western Panama. South American populations are patchily distributed along the Andes, occurring in the Santa M...
Least Concern
- The White-fronted Tyrannulet was historically classified in the genus *Phylloscartes*, but recent genetic analysis moved it to *Acrochordopus*, highlighting ongoing refinements in avian taxonomy. - Despite its small size, it's known for its extremely active foraging style, constantly flitting a...
