LC
Brambling Fringilla montifringilla



Justification

Justification of Red List category
This species has an extremely large range and the population size is extremely large, hence does not approach threatened thresholds for the range or population size criteria. Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion. For these reasons the species is evaluated as Least Concern.

Population justification
In Europe, the total population size is estimated at 14,000,000-26,000,000 mature individuals, with 7,030,000-13,000,000 breeding pairs (BirdLife International 2021), and comprises approximately 25% of the species' global range, so a very preliminary estimate of the global population size is between 56,000,000-104,000,000 mature individuals, although further validation of this estimate is desirable. In Europe, the species' population is considered to have undergone a small decline over three generations (10 years) (BirdLife International 2021). Based on these data, and the proportion of the species' global range that this region holds, the global population size is considered to be decreasing slowly over three generations.

Ecology

This species breeds in birch (Betula) and conifer woodland and also in mixed deciduous and conifer woods. Along the northern edge of the tundra it occurs in dwarf birch and willow (Salix) scrub and farther south in riverine alder (Alnus). During the non-breeding season it is found mainly in areas of deciduous trees, including woods, forests and small copses and shelter-belts, especially those containing beech (Fagus) or hornbeam (Carpinus), along edges of open agricultural fields, as well as in weedy and stubble fields and orchards. It breeds from May to early August and is monogamous. The nest is built above ground in a fork or against the trunk of a tree, or exceptionally low down in scrub or on the ground. It is a large, loose cup of grass, heather, birch or juniper bark strips, moss, lichens, plant down, animal hair or fur, feathers and cobwebs, sometimes with pieces of string or paper added. Normally lays five to seven eggs (Clement and Arkhipov 2016). It feeds on seeds and berries and in the summer on invertebrates as well. In its winter quarters it specialises in beechnuts (Snow and Perrins 1998). The species is migratory, although a small number in Scandinavia are resident (Clement and Arkhipov 2016).

Threats

Birds in subalpine Fennoscandia vary annually, apparently alongside the abundance of caterpillars of autumnal moth (Epirrita autumnata) and winter moth (Operophtera brumata). In the southern Urals and southern Siberia, years with high breeding numbers are generally followed by years of complete absence (Clement and Arkhipov 2016).
