Effects of Human Activity

Shooting And Trapping

Legislation prohibits shooting and trapping as a systematic or organized threat. Collister (Collister 1989) notes, however, that 14% of recoveries of Purple Finches banded in Alberta were shot without scientific permits, and 3% were caught in snares.

Pesticides And Other Contaminants/Toxics

No reported effects.

Ingestion Of Plastics, Lead, Etc

No reported effects.

Collisions With Stationary/Moving Structure Or Objects

Reported sources of mortality due to collision include motor vehicles, windows, other stationary objects (Weaver 1940, Collister 1989, W. E. Cook pers. comm.).

Degradation Of Habitat

Moderate logging potentially beneficial because Purple Finch prefers open wooded habitats (Keller 1990). Extensive clear-cutting likely to reduce population by eliminating habitat (Verner and Larson 1989).

Disturbance At Nest And Roost Sites

Human disturbance occasionally causes nest abandonment, and tree-trimming activities may destroy some nests in conifer plantations (NRCP data; 5/202 nests with known outcomes, 2.5%). No information on population consequences of this activity.

Human/Research Impacts

Research impacts almost certainly minimal, if only because minimal research conducted on this species. Effects of outdoor lighting on ability to orient properly during migration noted (Ferrell 1975), but no information on demographic consequences.

Management

Conservation Status

No evidence of immediate danger of extinction, although declines of northern and eastern populations require monitoring.

Measures Proposed And Taken

None.
