Synallaxis castanea
The Black-throated Spinetail (Synallaxis castanea) is a small, distinctive passerine bird endemic to the humid montane forests of northern Venezuela, belonging to the Furnariidae family of ovenbirds and woodcreepers.

Its relatively short tail is composed of stiffened feather...
This species primarily inhabits humid montane cloud forests, dense undergrowth, and bamboo thickets at elevations typically ranging from 1,200 to 2,200 meters (3,900 to 7,200 feet). It prefers areas with thick vegetation, often near forest edges or clearings with abundant secondary growth.
Its diet consists almost exclusively of insects and other small arthropods, which it obtains by gleaning meticulously from dense foliage and bark within its forest habitat.
