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)
- Supplemental
BAIS Surveys
- Pursue Grassland Bird Monitoring including BAIS if pilot study
results are positive (Canadian Action Plan); Conduct count-based
surveys of all bird species, including priority species (like BAIS) in
mixed grasslands (Montana); Conduct an inventory of BAIS wintering areas (
Arizona
); Improve BAIS bird and habitat monitoring on the wintering grounds
(Canadian Action Plan)
Habitat
Needs/Ecology/Life History
- Determine
patch size requirements for BAIS (in winter) (
Arizona
)
- Studies
of vocalization in BAIS (song development, acquisition, song-type
function, female recognition) (BNA)
- see
needs under "Wintering" and "Demographics"
Effects
of Management Practices
- Determine
the responses of BAIS to different management techniques (in winter) (
Arizona
)
- Examine
reproductive success of BAIS in native grasslands and various
categories of non-native grasslands (demographics, seasonal food
abundance, vegetative characteristics & wet and dry summers) (BNA)
- see
needs under "Demographics"
Landscape
- see
needs under “Demographics”
Wintering
- Winter
distribution
- Study the winter range/distribution of BAIS (
Mexico
& southwest
U.S.
) (
Arizona
; BNA)
- Winter
Habitat Needs
– Determine state-specific habitat requirements for wintering BAIS
(New Mexico; Arizona); Determine if the unfragmented grasslands around
Marfa, TX are important to wintering BAIS (TARP); Winter habits,
habitat conditions (additional studies in Mexico and SW U.S. to
determine habitats used, responses to land management, behavior, site
fidelity) (BNA)
- See
needs under “Habitat Needs…”, “Effects of Management
Practices” and "Monitoring"
Invasives/Exotics/Disease/Parasites/Contaminants
- Determine
effects of exotics on grassland habitat suitability for priority
species including BAIS (
Montana
)
Demographics
- Demographic
responses to habitat - Study the reproductive success of BAIS in different habitats
i.e. native and non-native grasslands and cropland (
Arizona
); Demography in relation to habitat quality and management regime for
both breeding and winter (Canadian Action Plan)
- Information
on BAIS breeding biology & demographics (What kinds of temporal
& spatial variation exist in nesting success? Effects of landscape
on demography?) (BNA)
