Fringilla montifringillabrambling

Geographic Range

Bramblings are widely distributed throughout the Palearctic region. Breeding distribution is throughout Fennoscandia, the Baltic States, and Russia. There is at least one record of a breeding pair in North America on Attu Island, Alaska. The winter range extends from western Europe throughout Eurasia, as far west as Japan. (Flint, et al., 1984; Pforr and Limbrunner, 1982; Sykes Jr. and Sonneborn, 1998)


Bramblings breed in subalpine birch and willow forests, boreal forests, and birch scrub. They appear to feed in shrubby habitat and on the ground in the early breeding season, but almost exclusively feed in trees in less shrubby habitat throughout the rest of the year. Bramblings are found in beech forests and agricultural fields in the winter. During this time, they may become nomadic in their search for a productive beech mast. Suitable wintering habitat is limited by snow cover, because they rely on seeds foraged from the ground. To prevent heat loss and conserve energy, bramblings leave their foraging sites to roost in more sheltered micro-habitats, such as coniferous tree stands situated at altitudes with minimum wind exposure. (Angell-Jacobsen, 1980; Jenni, 1987; Jenni, 1991; Pforr and Limbrunner, 1982; Svensson, et al., 2009)

Physical Description

Bramblings are medium-sized finches with long wings and tail. They have black tails and white rumps. The wings are mostly black, but the median and lesser secondary coverts are orange, which gives the bird a distinct appearance. Their bellies are white and the flanks have rows of black speckles. Adult males have orange throats throughout the year, while adult females have lightly colored grayish orange throats. On adult breeding males the bill is black while the head varies from mottled gray to completely black. The backs of breeding males are solid black. In non-breeding males, the head is mottled gray, the bill is yellow, and the back is mottled black, orange, and gray. Female bramblings have gray heads and yellow bills throughout the year. The feathers on their backs are gray with orange/brown tips, which give the back a scaled appearance. In flight, bramblings appear long-winged and have relatively long tails. (Lohmus and Silverin, 1999; Sibley, 2000; Svensson, et al., 2009)

Shortly after arriving on the breeding grounds, bramblings begin broadcasting for mating partners in small groups. Females seem to select mates based on song and physical characteristics rather than nest site selection. For this reason brambling are not breeding site tenacious, and appear to maintain some of their nomadic behavior during the breeding season.

Male bramblings appear on their breeding grounds in late April and early May. After mating occurs, the nest site is selected by the pair, and the two defend the nesting territory. Territorial males attack intruder males that are in their breeding territory and females attack any intruder near the nest site. They build cup-shaped nests, primarily in the low forks of birch and spruce trees. Nests are made up of grass, hair, birch bark, and moss. Females lay 5 to 7 oval, blue eggs with reddish markings. Incubation lasts 11 to 12 days and the young remain in the nest for up to two weeks. They produce 1 to 2 broods per breeding season. Bramblings have also been shown to be effective in protecting their nests against nest parasites, like common cuckoos (Cuculus canorus), by rejecting eggs that are not similar to their own eggs. (Alsop III, 2006; Lindstrom, 1987; Lohmus and Silverin, 1999; Mikkonen, 1983; Svensson, et al., 2009; Vikan, et al., 2010)

Bramblings are highly nomadic in the winter and retain some of their nomadism during the breeding season. Males banded on their breeding grounds have been recaptured as far as 600 km from the banding site the next breeding season. Small groups are established during breeding season, and nests are even near each other in sub-alpine birch forests. There is evidence of male aggression at breeding sites and pairs defend nesting territory. Foraging behavior varies from gleaning insects in trees and bushes to picking seeds off of the ground. (Lindstrom, 1990; Lohmus and Silverin, 1999)

Home Range

Home range size of bramblings is not reported in the literature, they are nomadic, so home range sizes may not be relevant.

Communication and Perception

Bramblings communicate vocally to establish breeding territory and attract mates. Males use a song to attract potential mates. Social chatter is used by roosting birds and call notes are used in flight. These vocalizations can be found at xeno-canto. Lohmus and Silverin (1999) suggested that some breeding males, especially those with lighter colored heads, might use female mimicry to increase mating success and to avoid aggressive interactions with other males. Bramblings are likely sensitive to ultra-violet (UV) light and may use visual cues in the UV spectrum to identify and reject eggs laid by nest parasites. (Avil and Moller, 2004)

Food Habits

During the winter, bramblings roosts can be as large as 20 million birds. Bramblings rely on beech mast in most of their range and densities are highest where beech mast is the greatest. They are also known to feed on seed in large agricultural fields in other parts of their range. During the breeding season, nomadism has been correlated to the abundance of the larva of Epirrita autumnata, a geometrid moth. These moths are an important food source for nestlings and juveniles. Bramblings will eat other seeds and insects as well. (Jenni, 1987; Lindstrom, 1987)

Bramblings are likely preyed on by aerial predators, such as small hawks and falcons.

Ecosystem Roles

Winter roosts can reach population sizes of several million birds. They scan large areas for suitable beech mast crops. Because they gather in such large numbers, they presumably play an important role as seed predators at foraging sites. Breeding bramblings may also be important predators of geometrid moth larvae. During migration they are preyed upon by several species of predatory birds. Common cuckoos are nest parasites of bramblings, although bramblings seem to be able to detect and reject their eggs. (Jenni, 1987; Lindstrom, 1987; Lindstrom, 1990)

Commensal/Parasitic Species

Economic Importance for Humans: Positive

Direct benefits of bramblings have not been described, although they do enrich the lives of bird-watchers, naturalists, and wildlife enthusiasts. Their predation on moth larvae and insects may positively impact agriculture and silviculture.

Economic Importance for Humans: Negative

Bramblings have no known negative impacts on human economies.

Conservation Status

Bramblings are common throughout most of their range. There is an estimated 13,000,000 to 22,000,000 breeding pairs in Europe alone and the breeding range extends as far as the Aleutian Islands. Bramblings are not considered threatened because of their large population size and large geographic range. (Butchart and Eckstrom, 2013)
