The Rufous-capped Warbler has a striking rufous-and-white head and a yellow throat and breast. It searches for insects in low brush and builds a domed nest on the ground.
Its head is rufous and white, and its throat and breast are bright yellow.
It searches for insects in low brush and tangled vegetation, sometimes flicking its long, narrow tail upward. It builds a domed nest on the ground, and both sexes sing.
It picks insects and other small invertebrates from low to mid-level vegetation and also eats berries.
The nest has a side entrance and is built of plant fibres with a thick lining. It is placed on the ground, often beneath large rocks or logs and concealed by vegetation.
On 19 July 1977, a female and a nest containing two eggs were documented in Cave Creek Canyon, Arizona.
