Synallaxis simoni
The Araguaia Spinetail (Synallaxis simoni) is a relatively small, drab member of the Furnariidae family, measuring approximately 16 cm in length and weighing around 15-18 grams. Its most striking field marks include a rich rufous crown, back, and wings that starkly contrast with its greyish underparts, often with a subtle, pale supercilium and loral area. A small blackish throat patch can sometimes be observed, and its long, graduated tail is frequently held cocked, a characteristic spinetail...
Primarily inhabits dense, tangled vegetation along the edges of rivers and streams, particularly within gallery forests and riparian thickets in low-lying areas.
Feeds mainly on small insects and other invertebrates, which it gleans from dense foliage and twigs in the understory.
The Araguaia Spinetail is typically a skulking and elusive bird, spending most of its time foraging low down in dense undergrowth. It is usually observed singly or in pairs, rarely joining mixed-species flocks. Its foraging strategy involves actively gleaning insects and other small invertebrates...
