Key
Reference(s):
BNA No. 93 (McCallum 1994)
Distribution:
Breeds locally from s-c British Columbia (Kamloops, Penticton), c
Washington, e Oregon, s Idaho, w Montana and n-c Colorado south to s-c
California (Palomar Mountain), s Arizona, s New Mexico, and w Texas
(Guadalupe, Chisos, and probably, David mountains); also in Coahuila,

(Sinaloa, Jalisco, Michoacán and Distrito Federal) south in the highlands
to
Guatemala
and
El Salvador
, casually north to s

Associations:
Montane forest, primarily open ponderosa pine association,
occasionally aspen; in migration, wooded area in lowlands and mountains
(upper Subtropical and Temperate
zones) (AOU 1998).

RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct
U.S.
nocturnal surveys (PIF Monitoring Needs doc); (similar) Conduct
nocturnal bird surveys in all habitats as needed to monitor priority
species including FLOW (
Montana
); Use standardized owl-monitoring protocol to follow trends (Canadian
Action Plan)
- Second
priority monitoring action – Conduct Mexican nocturnal surveys (PIF
Monitoring Needs doc)
- Third
priority monitoring action – Conduct migration monitoring (PIF
Monitoring Needs doc)
- High
priority candidate for rapid status assessment (PIF Monitoring Needs
doc)
- Supplemental
FLOW Surveys
- Thorough inventory of FLOW distribution in Blue and Northern
Glaciated Mts (Oregon/Washington); Determine
presence and distribution of FLOW in MT (
Montana
); More information on
distribution & abundance of FLOW in CA (
California
); Determine population status and ecology of FLOW in NM (
New Mexico
)
- Identify
FLOW nesting areas
- Nocturnal surveys needed to locate nesting localities (
California
); Survey nesting FLOW in NV (
Nevada
)
- Habitat
surveys
- Inventory of size, location and condition of old-growth stands of
Douglas-fir/ponderosa pine on drier, lower elevation sites (focus
species including FLOW) (
Montana
); Survey other suitable habitat to determine full extent of range in
British Columbia
(Canadian Action Plan)
Habitat
Needs/Ecology/Life History
- Study
FLOW nesting ecology and habitat use (Oregon/Washington)
Effects
of Management Practices
- General
management questions
- Identify treatment conditions that attract FLOW (Oregon/Washington);
Effects of habitat management and spatial patterns on demography of
FLOW (Canadian Action Plan)
- Effects
of silvicultural practices (controlled burns, thinning) on FLOW (BNA)
- Value
of nest boxes
- Determine if nest boxes will be useful as a management tool for FLOW
(BNA); Study factors leading to acceptance of nest boxes (Canadian
Action Plan)
Migration
- Identify
migration corridors of FLOW (
California
)
Wintering
- Delineate
range and study ecology of species in wintering area (Canadian Action
Plan)
- Virtually
nothing is published on winter behavior & range of FLOW (BNA)
