Spinus pinus
Adults are brown on the upperparts and pale on the underparts, with heavy streaking throughout. They have short forked tails. Their bills are conical like most finches but are more elongated and slender than those of other co-occurring finches. There is subtle yellow edging on the wings and tail (pic 2). When agitated or disturbed it can show a crown (pic 3).
Spotted in my backyard. Although Pine Siskins prefer evergreen or mixed evergreen and deciduous forests with open canopies, they are opportunistic and adaptable in their search for seeds. They'll forage in weedy fields, scrubby thickets, or backyards and gardens. And they'll flock around feeders, especially thistle feeders, in woodlands and suburbs.
Although considered Washington's most common finch, the pine siskin has suffered a significant annual decline in population since 1966, according to the Breeding Bird Survey. Due to the irruptive nature of this species, populations vary widely from year to year, and trends can be difficult to interpret. Parasitism by brown-headed cowbirds can have a significant impact on pine siskin productivity, and forest fragmentation has increased their contact with cowbirds. Maintaining large tracts of coniferous forest will help keep this bird common.
