Sparrows: Passeridae - Snow Finch (montifringilla Nivalis): Species Accounts

finches birds found mountains

Physical characteristics: Snow finches are large, plumpish finch-like birds with a blue-gray head, brownish body, and white colorings that are visible while flying (on wings nearest the body and on tail except for dark brown bar that goes down the middle and dark brown spots across the ends). Males and females look similar, with females being paler and less white on the wings. Adults are 6.7 to 6.9 inches (17.0 to 17.5 centimeters) long and weigh between 28 and 54 centimeters).


Geographic range: They are found only on mountains over 6,600 feet (2,000 meters) in Europe and Asia.


Habitat: They are found in areas of barren, rocky ground and mountains at elevations from 6,600 to 11,500 feet (2,000 to 3,500 meters). They are sometimes found near buildings that are located within these mountainous areas.


Diet: Their diet consists of grains during the winter, but will eat invertebrates during other seasons. Often, snow finches feed on seeds Snow finches are found only on mountains over 6,600 feet (2,000 meters) in Europe and Asia. (Illustration by Amanda Humphrey.

Behavior and reproduction: Snow finches are very social birds, often forming wandering groups and large flocks outside the breeding season. They spend most of their time on the ground hopping around with their wings folded. During the breeding season, they form loose colonies of up to six pairs. They build nests in rock crevices or holes in buildings. Nests are often built where trees are no longer found. They fill the crevice or hole with grasses and moss and line it with feathers. Females lay three to four eggs. The incubation period is thirteen to fourteen days, and the fledgling period is twenty to twenty-one days. Two clutches are possible each year. Both parents help to fed and take care of the young.


Snow finches and people: There is no known significant relationship between people and snow finches.


Conservation status: Snow finches are considered common. ∎
