Lathrotriccus euleri
The Euler's Flycatcher, *Lathrotriccus euleri*, is a small, rather inconspicuous tyrant flycatcher, measuring approximately 12-14 cm (4.7-5.5 inches) in length and weighing around 9-13 grams (0.3-0.5 ounces). Its plumage is generally olive-brown on the upperparts, contrasting with a whitish throat, a pale buffy-yellowish belly, and dull greyish sides. Distinctive field marks include a prominent, pale whitish eye-ring and two faint, buffy wing-bars, which can be subtle. Taxonomically, it belon...
This species primarily inhabits humid lowland and montane forests, often found in dense understory, forest edges, and secondary growth, frequently near water sources. It can be found from sea level up to elevations of 2,000 meters or more.
The diet of the Euler's Flycatcher consists predominantly of insects, including flies, beetles, moths, and wasps, which it captures by sallying from a perch or gleaning from vegetation. Occasionally, it may also consume small spiders or tiny fruits.
Euler's Flycatchers are diurnal birds, typically observed alone or in pairs, often sitting quietly on low to mid-level perches within the forest understory. Their foraging strategy primarily involves 'sally-gleaning' or 'sally-striking,' where they make short, quick flights from a perch to snatch...
The Euler's Flycatcher boasts an extensive, yet complex, distribution across the Neotropics. Its range spans parts of Central America, specifically eastern Panama, and widely across South America. Resident populations are found from northern Colombia and Venezuela, through the Guianas, Ecuador, P...
