Megaxenops parnaguae
The Great Xenops (*Megaxenops parnaguae*), a striking member of the Ovenbird family (Furnariidae), is a medium-sized passerine, typically measuring 15-16 cm (6 inches) in length and weighing around 20-25 grams. Its plumage is characterized by plain rufous to chestnut upperparts, contrasting with a whitish throat and buffy breast and belly. A distinctive pale eye-ring gives it a spectacled appearance, while its long, pointed, and slightly decurved pale pinkish or yellowish bill is a key field ...
This species primarily inhabits arid and semi-arid deciduous woodlands, caatinga, and gallery forests within cerrado transition zones, typically found from lowlands up to elevations of about 900 meters (3,000 feet).
The Great Xenops feeds predominantly on insects and other invertebrates, such as beetles, ants, and various larvae, which it gleans and probes from tree bark and foliage.
The Great Xenops is a diurnal, arboreal insectivore, often observed singly or in pairs, sometimes joining mixed-species flocks with other Furnariids. It employs a distinctive foraging strategy, methodically gleaning insects and larvae from bark, twigs, and foliage, often working its way upwards a...
