Mourning Dove
Primary flight feather (remex), likely P7-P9 based on moderate asymmetry and elongation.

Mourning Dove

Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Columbiformes; Family: Columbidae; Genus: Zenaida; Species: Zenaida macroura

Family: Columbidae (Pigeons and Doves)

Shape
Asymmetrical vane with a narrower leading edge and wider trailing edge; elongated, slender profile with a slightly tapered, rounded tip and minimal emargination.
Size
Estimated 12-14 cm (4.7-5.5 inches) in length. This is consistent with the primary flight feathers of an adult Mourning Dove, which typically measure between 11 and 15 cm.
Rarity
Very Common; one of the most abundant and widespread birds in North America.

Description

A slender, graceful feather from a medium-sized bird known for its mournful 'coo-oo' call. The bird itself is soft grey-brown with black spots on the wing coverts and a long, pointed tail. Known for their fast, direct flight and the distinct whistling sound their wings make upon takeoff.

Colour & Pattern

Uniform mousy-grey to brownish-grey on the dorsal surface; the ventral side is slightly paler with a silvery sheen. The rachis is dark. No distinct banding or spots are present, which is typical for the primary feathers of this species.

Barb Structure

Densely interlocked (pennaceous) throughout the majority of the vane for flight efficiency; semi-plumulaceous (fluffy) barbs are visible at the very base (calamus area) near the superior umbilicus.

Texture & Surface

Smooth, matte, and slightly velvety to the touch. The vane is somewhat flexible but maintains a firm aerodynamic shape. There is a slight powdery feel characteristic of Columbids.

Key Features

Uniform grey coloration, distinct asymmetry of the vane, slender 'dagger' shape, and lack of Terminal bands or bold markings distinguish it from similar-sized raptor or jay feathers.

Habitat

Extremely versatile; found in open woodlands, agricultural fields, grasslands, suburban gardens, and urban parks. Avoids dense, unbroken forests.

Geographic Range

Abundant across North America, from southern Canada through the United States to Mexico and Central America. Most populations are resident, though northernmost birds migrate south for winter.

Ecological Role

Primarily a granivore (seed-eater), playing a role in seed dispersal. They are a vital prey species for many birds of prey, including Cooper's Hawks and Falcons.

Similar Species

Rock Pigeon (larger, broader, often darker), Eurasian Collared-Dove (very similar, but primaries tend to be slightly darker/sootier), White-winged Dove (would show a bold white patch).

Interesting Facts

The whistling sound heard when a Mourning Dove takes off is not vocal; it is 'wing-whistling' caused by the specialized shape of the primary feathers vibrating against the air.

Condition Notes

Fair to Good. There is some minor fraying ('zipper' separation) and wear at the distal tip, suggesting this may be a molted feather from a bird toward the end of its annual molt cycle.
