RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct boreal surveys (PIF Monitoring Needs
doc)
- Second
priority monitoring action – Improve the Breeding Bird Survey (BBS)
(PIF Monitoring Needs doc); (similar) Improve BBS precision if
possible (Canadian Action Plan)
- Supplemental
OSFL Surveys
- Develop monitoring protocols for patchily distributed birds
(including OSFL) in peatlands (Adirondack Mts); Conduct point counts
for birds (including OSFL) in southeast Alaska across the US Forest
Service’s 21 geographic provinces (Alaska); Evaluate ability of
migration monitoring to track eastern populations of OSFL (Canadian
Action Plan); Determine population status and trends for OSFLs in
Nevada and Arizona (Nevada; Arizona)
- Determine
causes of population declines of OSFL (Adirondack Mts; Northern Ridge
& Valley; Canadian Action Plan)
- Habitat
Monitoring
- Monitor changes in mature forest cover and construct bird-habitat
models for central Alaska (including OSFLs) (Alaska); Identify
important patches of conifer forest supporting priority birds
including OSFL (Northern Ridge & Valley); Monitor
"health" and succession of important peatland sites for OSFL
(Adirondack Mts); Develop a method to remotely sense and locate
optimum peatland habitats (including OSFL habitat) (Adirondack Mts)
- See
needs under "Wintering"
Habitat
Needs/Ecology/Life History
- Determine
more specific habitat preferences/needs for OSFLs (
Nevada
; Northern Ridge & Valley)
- Collect
natural history information on OSFL in
Arizona
(
Arizona
)
- Effects
of various environmental attributes (landscape features, food
resources, predation) across various habitats, landscapes, &
forest management regimes (harvested, burned, unmanaged) on
productivity of OSFL (BNA)
- Determine
if food resources (prey availability) limit OSFL productivity (BNA)
- see
needs under "Wintering" and "Effects of
Management..."
Effects
of Management Practices
- Determine
management practices that enhance populations of OSFL (Adironack Mts)
- Effects
of Silvicultural Practices - Determine effects of forestry practices on
OSFL demography (Canadian Action Plan); Compare
early-successional habitats resulting from natural disturbances vs.
forestry practices for high-priority species (including OSFL)
(Adirondack Mts); Determine
whether logged areas serve as ecological traps or sinks for species
like OSFLs (Montana); Determine optimal habitat requirements for
productivity (old growth vs logged vs burned vs natural regeneration
(California)
- Evaluate
the effects of insect control on OSFLs (
Arizona
)
- Effects
of Fire
- Determine the most appropriate fire treatment for OSFL in Mixed
Conifer habitat (Arizona); Study
bird use (including OSFL) of burned forest patches (Montana);
Determine where, when and how to introduce fire; where and how much to
salvage (Montana)
- see
needs under "Habitat Needs/Ecology…”, “Demographics”, and
“Wintering"
Effects
of Human Development/Disturbance
- Study
impacts of human development on early successional species (including
OSFL) (Adirondack Mts)
Landscape
- Study
the differences between historic and existing landscape conditions for
OSFLs (
Montana
)
- Determine
the landscape-level habitat conditions associated with OSFL nesting
success (
Montana
)
Species
Interactions
- Study
beaver activity, meadow succession, and their role in creating or
maintaining peatlands (Adirondack Mts)
- Effects
of hemlock loss due to woolly adelgid on bird populations including
OSFL (Northern Ridge & Valley)
Predation

if predation limits OSFL productivity (BNA)
Wintering
- Determine
range & status of OSFL on wintering grounds, including overwinter
survivorship (Canadian Action Plan;
California
; BNA)
- Investigate
possible OSFL habitat loss on wintering grounds (
Arizona
)
- Evaluate
ecology of OSFL on wintering grounds, including habitat selection,
resource use, competition, & effects of forest alteration on
wintering populations (BNA)
Demographics
- Reproductive
success
- Compare the reproductive success of OSFL in different habitats
including naturally disturbed, managed, and post-fire habitats
(Oregon/Washington;
Arizona
;
Montana
); Determine the relationship between reproductive success of OSFL and
habitat composition and structure (Oregon/Washington)
- Effect
of insect availability and predator densities on OSFL nest success
(Oregon/Washington)
