The Short-crested Flycatcher (*Myiarchus ferox*) is a bold and energetic songbird of South American woodlands and forest edges, easily recognized by its shaggy, slightly raised crown feathers that give it a perpetually alert expression. This medium-sized flycatcher boasts a warm brown back, pale yellow belly, and a long, dark tail with rufous inner webs, often flicked and spread in a distinctive, nervous habit. Its most unique feature is its loud, explosive voice: a sharp, rolling “*re-e-e-e-e-e*” that descends in pitch, often delivered from an exposed perch as it sallies out to snatch insects mid-air. Unlike many *Myiarchus* species, the Short-crested Flycatcher prefers lower, more cluttered perches near water, and its fierce territorial behavior makes it a dominant presence among smaller birds in its humid lowland habitats.

Fun Facts

Despite its scientific name *ferox* meaning "fierce," this flycatcher is a master of stealthy deception, often mimicking the calls of other bird species to confuse predators or rivals. It has a quirky habit of vigorously flicking its tail and crest in a jerky, mechanical motion while foraging, a behavior thought to startle insects into revealing themselves. One unique adaptation is its nest-building strategy: it frequently takes over abandoned woodpecker holes or natural cavities, but will aggressively line the entrance with snake skin or shed feathers—a bizarre deterrent against nest raiders. Additionally, these birds have been observed engaging in "anting," where they deliberately rub ants on their feathers to use the formic acid as a natural insecticide against parasites.

Habitats & Distribution

The Short-crested Flycatcher is found across a broad swath of South America east of the Andes, from Colombia, Venezuela, and the Guianas south through much of Brazil, Bolivia, Paraguay, and into northern Argentina. It inhabits a variety of open and semi-open wooded environments, including gallery forests, forest edges, secondary growth, savanna woodlands, and plantations, often near water. It avoids the interior of dense, humid primary forests, preferring more disturbed or transitional habitats from lowlands up to about 1,500 meters in elevation.

Behaviours & Reproduction

The Short-crested Flycatcher is generally solitary or found in pairs, maintaining a defined territory during the breeding season. Mating appears to be monogamous for the season, with males using vocalizations and perch displays to attract a female, often engaging in chases and wing-fluttering rituals. The species does not exhibit any unique or elaborate reproductive strategies; the female builds a cup-shaped nest in a natural cavity or old woodpecker hole, lining it with soft plant fibers. She lays a typical clutch of 2-4 eggs, which she incubates alone, while the male assists by bringing food to the nest and defending the territory. Both parents feed the altricial chicks until they fledge, with no evidence of cooperative breeding or brood parasitism avoidance beyond standard nest defense.

Diet

The Short-crested Flycatcher (*Myiarchus ferox*) is primarily an insectivore, with its diet heavily dominated by a wide variety of flying insects such as flies, beetles, moths, and wasps, which it expertly catches in mid-air using agile sallying flights from a perch. Interestingly, this bird is not strictly an aerial hunter; it also actively gleans caterpillars, spiders, and other small arthropods from leaves and bark. During the non-breeding season, its diet shifts opportunistically to include small fruits and berries, making it a partial frugivore. A notable feeding behavior is its tendency to follow army ant swarms, where it snatches insects and other arthropods flushed by the ants’ advance, a strategy that maximizes foraging efficiency in tropical forests.

Colors

The Short-crested Flycatcher is primarily olive-brown above with a slightly grayer head and a short, bushy crest. Its throat and breast are pale gray, transitioning to a pale yellow belly and undertail coverts. It has two pale wing bars, and the inner webs of the tail feathers are rufous, a key field mark. It lacks bold or unique markings, relying on its dull, uniform coloration for camouflage within its forest and woodland habitats.
