Conservation Status
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.

Famous quotes containing the words conservation and/or status:
“A country grows in history not only because of the heroism of its troops on the field of battle, it grows also when it turns to justice and to right for the conservation of its interests.”
—Aristide Briand (1862–1932)
“Knowing how beleaguered working mothers truly are—knowing because I am one of them—I am still amazed at how one need only say “I work” to be forgiven all expectation, to be assigned almost a handicapped status that no decent human being would burden further with demands. “I work” has become the universally accepted excuse, invoked as an all-purpose explanation for bowing out, not participating, letting others down, or otherwise behaving inexcusably.”
—Melinda M. Marshall (20th century)
