Tolmomyias flaviventris
The Ochre-lored Flatbill (*Tolmomyias flaviventris*) is a vibrant and distinctive member of the tyrant flycatcher family, Tyrannidae, native to the Neotropics. Measuring about 12-13 cm in length and weighing 10-15 grams, this small passerine is easily recognized by its bright yellow underparts, olive-green back, and, most notably, a diagnostic ochre-yellow patch (lore) between its eye and its broad, flattened bill. This flattened bill, dark above and paler below, is a key adaptation for its i...
Found primarily in humid lowland and foothill forests, forest edges, clearings with scattered trees, and secondary growth up to approximately 1,200 meters in elevation, but most common below 800 meters.
Primarily insectivorous, feeding on a wide variety of insects and other arthropods including beetles, flies, wasps, caterpillars, and spiders. Occasionally consumes small berries.
Ochre-lored Flatbills are active diurnal foragers, typically observed alone or in pairs, though they may join mixed-species flocks outside the breeding season. Their foraging strategy involves sallying out from a perch to snatch insects in mid-air (flycatching) or gleaning arthropods from foliage...
The Ochre-lored Flatbill boasts an extensive and robust geographic distribution spanning much of the Neotropics. Its range initiates in Central America, specifically from southeastern Costa Rica and Panama, extending southward throughout vast portions of northern and central South America. Key co...
