 Rufous Hummingbird

 

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).

PIF Continental Plan Monitoring Needs Category:  ** (Long-term population trend monitoring considered adequate, but some issues (e.g., bias) may not 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)
