Common
Name: Rufous Hummingbird (RUHU)
Scientific
Name:
Selasphorus
rufus
Global/Continental
Conservation Status: Not
on IUCN 2004 Red List
National-level
Conservation Status:
U.S.
– Bird of Conservation Concern
Key
Reference(s):
BNA No. 53 (Calder 1993)
Distribution:
Breeds from s Alaska (west to Prince William Sound), s Yukon, w and
s British Columbia (including Queen Charlotte Islands), w-c Alberta, and w
Montana south, primarily in the mountains, to nw California (Humboldt
County), e Oregon, c Idaho, and w Wyoming.
Winters primarily from Sinaloa and
Chihuahua
south to
Oaxaca
,
Mexico
, Distrito Federal, and w
Veracruz
. Also over much of the
Gulf
Coast
region from c and e
Texas
to nw
Florida
, casually northward (usually unsuccessfully) through much of the e
United States
. Also casually to rarely in
British Columbia
and coastal s
California
(AOU 1998).
Habitat
Associations:
Coniferous forest edge, second growth, thickets, and brushy
hillsides, foraging in adjacent scrubby areas and meadows; in winter,
primarily pine-oak woodland; in migration, primarily lowlands in spring
but montane meadows in fall (AOU 1998).

be accounted for)
RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – NOTE: Breeding
Bird Survey (BBS) provides acceptable data at the continental level (PIF
Monitoring Needs doc)
- Second
priority monitoring action – Improve the BBS (PIF Monitoring Needs
doc); (similar) Determine if non-linear analysis of BBS improves
precision (Canadian Action Plan)
- Supplemental
RUHU Surveys
- Develop statewide bird monitoring efforts (including RUHUs) that
include riparian shrub habitats (
Montana
); Conduct point counts for birds (including RUHUs) in se
Alaska
across the USFS’s 21 geographic provinces (
Alaska
)
- Determine
causes of RUHU population declines if they persist (Canadian Action
Plan)
Habitat
Needs/Ecology/Life History
- RUHU
food sources
- Identify the important nectar-producing plants for RUHUs; and
determine the patch size, distribution, and number of nectar-producing
plants required by RUHUs (Oregon/Washington)
- Monitor
changes in mature forest cover and construct bird-habitat models in
southcoastal
Alaska
(
Alaska
)
- See
needs under “Demographics”
Demographics
- Compare
the reproductive viability of RUHU (nest success/productivity) in
early- and late-successional habitats (Oregon/Washington)
