An omnivore, the band-tailed pigeon will eat the nuts, seeds, berries, blossoms, but also insects. When in season it is also known to eat domestic crops such as cherries, berries, oats, barley and wheat.

Nesting materials are provided by the male and consist mainly of twigs and pine needles. The female lays 1, rarely 2 eggs which are incubated by both parents for 18-20 days. The chicks fledge 28-30 days after hatching.

IUCN status - LC (Least concern)
This species has an extremely large breeding range and a global population estimated at 4 million individuals. This species was hunted to low numbers in the beginning of the 20th century, but since then recovered, following hunting regulations. The population is believed to be currently facing a very small decline, which is not sufficient to cause the species to be considered threatened.
