Odontorchilus cinereus
The Tooth-billed Wren, *Odontorchilus cinereus*, is a remarkably inconspicuous member of the Troglodytidae family, known for its unique bill morphology that sets it apart even among its diverse kin. Averaging about 12-13 cm (4.7-5.1 inches) in length and weighing around 10-12 grams, this small, slender wren is predominantly grayish-brown above, with a clean white throat and belly, finely barred flanks and undertail coverts. Its most distinctive field mark, aside from its overall cryptic pluma...
This species primarily inhabits the canopy and subcanopy of humid tropical and subtropical lowland evergreen forests, often found in transitional zones near montane areas, typically ranging from 200 to 1,200 meters in elevation.
The diet of the Tooth-billed Wren consists primarily of small insects, spiders, and other arthropods, which it expertly gleans from the leaves, bark, and crevices of high canopy branches.
The Tooth-billed Wren is a largely arboreal and highly active bird, spending its days methodically foraging high in the forest canopy. It is frequently observed participating in mixed-species foraging flocks, moving rapidly through the foliage, gleaning insects and spiders from leaves, bark, and ...
The Tooth-billed Wren exhibits a disjunct distribution across the humid lowland forests of northern South America. Its primary range includes a significant portion of the Amazon Basin, extending from eastern Ecuador and northern Peru eastward through southern Colombia and central Brazil. A separa...
