Habitat
Forest edge, clearings, and high-altitude shrubland, sometimes in areas best described as cloud forest. In Mexico often in areas with mixture of pine and other trees. Often described as preferring the thickest undergrowth.
Behaviour
Likes to keep hidden except when singing, and probably not easy to see even then. Not a tremendously active bird. The White-naped Brushfinch moves, or hops, around on the ground looking on , or under, leaves they find on the ground as they look for food. They also look for food on brush close to the ground.
Diet
They eat a variety of seeds and insects which are to be found on or near the ground. And may be found hopping on the ground following swarms of army ants.
Breeding
This species uses various dry vegetable materials to build a nest without a top covering and lines it with additional material more suited to cushioning the eggs. . It's placed around a half meter to as much as 3 meters above the ground in in heavier brush or occasionally on the earth. The clutch generally consists of two to three white eggs. Times of this process vary from April to September depending on the location.
Vocalisations
A series of about 6 notes given in a measured, steady pace.
