Patagioenas fasciata is a large pigeon found across montane regions of western North and South America, primarily inhabiting elevations between 4,900 and 11,500 feet. It inhabits coniferous and mixed woodlands, cloud forests, and forested slopes, where it is often seen in small flocks flying swiftly above the canopy or perched in tall trees.

The species measures about 14 to 15 inches in length. Adults have dark gray upperparts with a faint pinkish wash on the breast, a pale gray belly, and a broad white collar on the nape that gives the bird its characteristic appearance. The head is slate-colored, the bill is dark with a small pale tip, and the eyes are yellowish-orange with red orbital skin. The tail is long and squared with a broad pale band. Patagioenas fasciata feeds mainly on berries, seeds, and occasionally acorns or buds, depending on seasonal availability. It is known to forage in both trees and on the ground. Breeding involves simple stick nests built in conifers or dense shrubs, usually with one egg per clutch. Vocalizations consist of a deep, rhythmic cooing series. This species is considered plentiful and is categorized as Least Concern in conservation assessments.
