Brown-capped Rosy-Finch
Common
Name: Brown-capped
Rosy-Finch (BCRF)
Scientific
Name:
Leucosticte
australis
Global/Continental
Conservation Status: Not on IUCN 2004 Red List
National-level
Conservation Status:
Nothing other than coverage under the Migratory Bird Treaty Act
Key
Reference(s):
BNA No. 536 (Johnson et al. 2000)
Distribution:
Breeds in the mountains from se
Wyoming
(
Medicine
Bow
Range
) south through
Colorado
to n
New Mexico
(
Santa Fe
region). Winters generally at
lower elevations in the breeding range (AOU 1998).
Habitat
Associations:
Barren, rocky, or grassy areas and cliffs among glaciers or beyond
timberline; in migration and winter also in open situations, fields,
cultivated lands, brushy areas, and around human habitation (AOU 1998).

RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
– Develop/implement Protocols
- Priority
monitoring action – Conduct high elevation surveys (PIF Monitoring
Needs doc); (similar) Develop techniques and protocols for monitoring
BCRF (
Colorado
)
- Second
priority monitoring action – Conduct new winter surveys (PIF
Monitoring Needs doc)
- High
priority candidate for rapid status assessment (PIF Monitoring Needs
doc)
- Document
population size and breeding of BCRFs in
New Mexico
(
New Mexico
)
- Identify
factors that regulate/limit BCRF population levels (
Colorado
; BNA)
- Determine
if the declining population trend shown in the Christmas Bird Count
data is real. What is the cause? (BNA)
Habitat
Needs/Ecology/Life History
- Investigate
seasonal movements and habitat needs of BCRFs (
Colorado
)
- Information
on breeding biology (time and place of pairing, nesting dates, sites,
clutch sizes, success rates, diet of young, growth in young, nest site
fidelity, annual and lifetime reproductive success, timing &
sequence of molt (BNA)
Migration
- Determine
whether there is differential migration between the sexes in BCRF
(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)
