Canada

Origin: Native

Regularity: Regularly occurring

Currently: Present

Confidence: Confident

Type of Residency: Year-round

Global Range: (250-20,000 square km (about 100-8000 square miles)) Endemic to Vancouver Island (American Ornithologists' Union 1957).

Comments: Generally found in mature forest; nests in woodpecker holes.

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Estimated Number of Occurrences: 81 to >300

Comments: Known breeding occurrences are scarce but undoubtedly breeds sparsely throughout range.

Canada

Rounded National Status Rank: N3 - Vulnerable

Rounded Global Status Rank: T3 - Vulnerable

Reasons: Widely, but sparsely distributed on Vancouver Island. Habitat declining because of large-scale forest harvesting.

Global Short Term Trend: Decline of 10-30%

Comments: Data are lacking but probably declining.

Degree of Threat: B : Moderately threatened throughout its range, communities provide natural resources that when exploited alter the composition and structure of the community over the long-term, but are apparently recoverable

Comments: Large-scale logging likely is reducing available habitat, with long-term population declines inevitable.

Biological Research Needs: Study taxonomic relationships with mainland G. C. GRINNELLI. Study impact of forestry activities on distribution and productivity of this owl. Determine habitat use.

Global Protection: Few to several (1-12) occurrences appropriately protected and managed
