Fairly stocky, sparrowlike bird endemic to highland forests. Occurs mainly in fir and humid pine-oak forest understory, often in brushy flower banks and shady canyons, where typically skulking and difficult to see well. Feeds on and near the ground, usually in pairs. White throat stands out in shady understory, but green head stripes can be difficult to see. Range does not overlap rather similar Chestnut-capped Brushfinch.
