Size
6–14.5 in long (15–37 cm) — a plump-bodied bird (typical for the family)
Habitat
Woodlands and forest edges, including wooded suburbs and parks.
Diet
Insects and spiders gleaned from foliage and bark, with seeds and berries in season.
Range
Recorded on 342 Breeding Bird Survey routes across 10 states, most concentrated in the Northern Pacific Rainforest.
Family
Columbidae · Forest birds

Band-tailed Pigeon Population Forecast

If the recent trend holds, Band-tailed Pigeon is projected to stay roughly flat through 2029, near 0.29 (95% range 0.13–0.45). A 5-year backtest shows a typical error of ±9%, with 100% of held-out values landing inside the 95% band.
