RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct Mexican Breeding Bird Surveys (BBS) (PIF
Monitoring Needs doc)
- Second
priority monitoring action – Conduct border (U.S-Mexico) bird
surveys (PIF Monitoring Needs doc)
- High
priority candidate for rapid status assessment (PIF Monitoring Needs
doc)
- Determine
conditions that result in drastic fluctuations in RWSP population
numbers (BNA)
- Document
the historic distribution of RWSP in light of El Niño events
and determine if high densities and peripheral range locations
are attributable to periodic increased rainfall (BNA)
Habitat
Needs/Ecology/Life History
- Information
on RWSP Breeding Ecology - Determine if RWSP breed twice in different habitats (
Sonoran
Desert
& desert grassland) (
Arizona
); Information on nesting behavior (pattern of nest attentiveness,
role of male, how far do young disperse?) (BNA); Define relationship
between rain and breeding (BNA)
- Information
on RWSP Molt
- Define relationship between breeding and molt (BNA); Clarify the
molt patterns in RWSP and relate to age and to spring vs summer
nesting seasons (BNA)
Effects
of Human Development/Disturbance
- Determine
how urbanization affects the RWSP (
Arizona
)
Landscape
- Determine
if habitat fragmentation affects RWSP (
Arizona
)
Predation
- Determine
if predation is a problem for RWSP (
Arizona
)
Nest
Parasitism
- Study
to what extent Brown-headed Cowbird parasitism affects RWSP (
Arizona
)
