RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct high elevation surveys (PIF Monitoring
Needs doc)
- Second
priority monitoring action – Conduct new winter surveys (PIF
Monitoring Needs doc); (similar) Monitor
winter populations of BLRF in
Nevada
(
Nevada
)
- Gather
baseline population information on BLRF (
Nevada
)
- High
priority candidate for rapid status assessment (PIF Monitoring Needs
doc)
- Identify
factors that regulate BLRF population levels (BNA)
- Is
the declining population trend shown in the Christmas Bird Count data
real? What is cause? (BNA)
Habitat
Needs/Ecology/Life History
- Information
on BLRF breeding biology (time & place of pairing, clutch size
& variation, timing of breeding related to latitude, nesting
success, annual or lifetime productivity, nest & egg measurements,
nestling growth, vocalizations, courtship, diet, duration & timing
of molt) (BNA)
Migration
- Determine
whether there is differential migration between the sexes in BLFR
(BNA)
Wintering
- More
information on BLRF in the winter season (BNA)
Demographics
- What
is the sex ratio of BCRF? Does it change with age class? Is there a
floating population of nonbreeding males? (BNA)
Genetics/Taxonomy/Systematics
- Is
BCRF genetically monogamous? (BNA)
