Band-tailed Pigeon
Common
Name: Band-tailed Pigeon (BTPI)
Scientific
Name:
Columba
fasciata
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. 530 (Keppie and Braun 2000)
Distribution:
Breeds (fasciata group)
from sw British Columbia south (primarily in mountains) through
Washington, Oregon, California, and w Nevada to s Baja California; from s
Nevada, Arizona, c Utah, n-c Colorado, New Mexico, and w Texas south
through the mountains of Mexico, Guatemala, El Salvador, and Honduras to
(at least formerly) n-c Nicaragua. Regular
in summer (and probably breeding) north to se
Alaska
(as far north as
Mitkof
Island
and the
Stikine
River
) and w-c
British Columbia
. Winters (fasciata
group) from w Washington, c California, c Arizona, c New Mexico (rarely),
and w Texas southward through the breeding range, occurring widely in
Mexico in the foothills at lower elevations than in the breeding season,
regularly north to sw British Columbia, rarely west to islands off the
coast of California, and east to Nevada (AOU 1998).
Note: albilinea group is
resident in Central and
South America
.
Habitat
Associations:
Temperate and mountain forests, primarily in oaks, less commonly in
coniferous forest, and locally in lowlands, foraging also in cultivated
areas; increasingly common in wooded suburbs in Pacific coastal region
(Subtropical and Temperate zones) (AOU 1998).

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 – Improve the BBS (PIF Monitoring Needs
doc); (similar) Test survey techniques that produce reliable
population estimates over large areas (BNA)
- Supplemental
Surveys
- Additional species monitoring in Ponderosa Pine in
New Mexico
for species including BTPI (
New Mexico
); Determine current population numbers for BTPI in
Arizona
(
Arizona
)
- Determine
causes of population decline; determine why BBS shows decline in
British Columbia
while range is expanding (Canadian Action Plan)
- See
needs under “Effects of Management”
Habitat
Needs/Ecology/Life History
- Determine
specific habitat needs for BTPI in Pine-Oak (
Arizona
)
- Determine
relationships between food abundance, breeding densities, &
productivity in BTPI (BNA)
- Determine
importance of mineral availability from grit or water at mineral
springs (BNA)
Effects
of Management Practices
- Monitor
BTPI in areas with and w/o salvage logging to determine effects (
Arizona
)
- Effects
of forest management & agricultural practices on BTPI (BNA)
- Evaluate
status & trends subsequent to closing of hunting (Canadian Action
Plan)
Effects
of Human Development/Disturbance
- Impacts
of hunting on BTPI, including crippling loss, magnitude of hunting in
Mexico
, and effects on survival estimates (BNA)
Invasives/Exotics/Disease/Parasites/Contaminants
- Effects
of disease, especially trichomoniasis, and pesticides on BTPI (BNA)
Demographics
- Population
models are needed, based on regional reproduction and survival
throughout annual cycle (Canadian Action Plan)
