Family: Columbidae (Pigeons and Doves)
- Shape
- Highly asymmetrical vane with a noticeably tapered, pointed tip; the leading edge is narrow while the trailing edge is broader and curved.
- Size
- Estimated 4-5 inches (10-13 cm) in length; this is consistent with the outer primary feathers of an adult Mourning Dove which typically range from 9 to 14 cm.
- Rarity
- Very Common; one of the most widespread and abundant birds in North America.

Description
A slender, medium-sized dove with a long, pointed tail. The bird is generally grayish-brown with black spots on the wings and a pinkish iridescent patch on the neck. They are known for their mournful 'coo-ah, coo, coo' call and the distinct whistling sound their wings make during takeoff.
Colour & Pattern
Dull brownish-tan to olive-gray on the upper surface with a slight silvery-gray sheen on the underside; no heavy banding is present, which is typical for the primary feathers of this species.
Barb Structure
Pennaceous; the barbs are tightly interlocked with microscopic hooklets (barbicels) typical of flight feathers to maintain aerodynamic integrity; plumulaceous fluff is minimal at the base.
Texture & Surface
Smooth, stiff, and slightly waxy to the touch; the surface has a matte to semi-glossy appearance designed for silent but efficient flight.
Key Features
Tapered, pointed tip; tan-gray uniform coloration; strong asymmetry of the vanes; relatively short calamus compared to total length.
Habitat
Extremely versatile: found in open woodlands, prairies, agricultural fields, suburban backyards, and urban parks; avoids dense, unbroken forests.
Geographic Range
Abundant across North America, from Southern Canada through the United States and Mexico into Central America; northern populations are migratory.
Ecological Role
Primary seed eater (granivore); they play a massive role in seed dispersal across open landscapes and serve as a vital prey species for small raptors like Cooper's Hawks.
Similar Species
White-winged Dove (has a distinct white patch), Eurasian Collared-Dove (larger, more gray/blue tones, broader tip), Rock Pigeon (much larger, darker gray).
Interesting Facts
The whistling sound heard when a Mourning Dove takes flight is not vocal; it is 'wing whistle' produced by the vibration of these specialized primary feathers acting as an alarm signal to other birds.
Condition Notes
Fair to Good; the feather shows significant 'zipper' separation (unlocked barbs) near the tip and edges, likely due to mechanical wear or handling after being found.
