RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct high elevation surveys (PIF Monitoring
Needs doc); (similar) Monitor montane shrubland species -
Conduct count-based surveys in montane shrublands of species including
CAHU (
Montana
); Monitor priority species including CAHU in montane riparian
habitats above 7,000 ft elevation (
Nevada
)
- Confirm
population status in
Canada
(Canadian Action Plan)
- Investigate
causes of population decline if decline is confirmed (Canadian Action
Plan)
Habitat
Needs/Ecology/Life History

of habitat suitability in seral shrub fields for hummingbirds
including CAHU (
Montana
)
- Information
on CAHU developmental biology, molt (BNA)
Demographics
- Develop
information on survivorship, reproductive success (BNA)
