This report summarizes information on the abundance and harvest of band-tailed pigeons (Patagioenas fasciata) in the western United States and British Columbia through 2009. The all-bird Breeding Bird Survey (BBS) provides and annual index to abundance of Interior and Pacific Coast band-tailed pigeons since 1966, while the MSS, implemented in 2004, was designed specifically to index abundance of Pacific Coast band-tailed pigeons. Harvest and hunter participation are estimated from the Migratory Bird Harvest Information Program. The BBS provided strong evidence that the abundance of Interior band-tailed pigeons decreased (4.0% per year, 95% credible interval = -8.3 to -0.8) over the long term (1966–2009). Also, abundance appeared to decrease during the recent 10 and 5 years, but credible intervals included zero. Current (2009) estimates of total harvest, active hunters, and total hunter days afield were 5,000 ± 1,250 (estimate ± SE) birds, 4,400 hunters, and 13,200 ± 2,829 days afield. Harvest comprised 8.3% hatching year birds during the 2009 season. For Pacific Coast band-tailed pigeons, the BBS provided strong evidence that abundance decreased (-2.6% per year, CI = -5.4 to -1.1) over the long term (1966–2009). Abundance appeared to decrease during the recent 10 and 5 years, but credible intervals included zero. The MSS, however, provided some evidence that abundance decreased (7.0% per year, CI = -14.0 to 0.0) over the recent 5 years. Current (2009) estimates of total harvest, active hunters, and total hunter days afield were 22,600 ± 3,113 birds, 9,700 hunters, and 24,400 ± 3,112 days afield. Composition of harvest was 21.3% hatching year birds during the 2009 season. Current estimates of the age-related vulnerability to harvest for these populations are unavailable.
