Common name:
canyon towhee (en); tico-tico-pardo (pt); tohi des canyons (fr); rascador pardo (es); braunrücken-grundammer (de)


Taxonomy:
Order Passeriformes
Family Emberizidae


Range:
This species is found in the south-western United States, in Colorado, Arizona, New Mexico and Texas, and in Mexico, down to Oaxaca.


Size:
These birds are 19-22 cm long and have a wingspan of 28-30 cm. They weigh 40-45 g.


Habitat:
These birds are found in arid scrublands, chaparral and pinyon-juniper woods, on desert foothills and canyons. They occur from sea level up to an altitude of 3.100 m.


Diet:
During winter they mainly feed on insects, while during spring and summer insects become an important part of their diet. They also eat fruits and berries when available.


Breeding:
Canyon towhees are monogamous and may mate for life. The nest is a bulky open cup, made of twigs, weeds and grasses, and lined with leaves, fine grass, strips of bark, and animal hair. It is usually placed in a small tree, dense scrub, or cactus, 1-4 m above the ground. The female lays 2-6 whitish eggs with reddish-brown spots, which she incubates alone for 11-12 days. The chicks are fed by both parents and fledge 9-10 days after hatching. Each pair may raise 2-3 broods per year.


Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population of 7 million individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
