Black-billed Magpie (also known as the American Magpie)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Pica, Species: Pica hudsonia
Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Highly asymmetrical vane, typical of primary flight feathers for aerodynamic lift. The tip is rounded but moderately tapered. The outer (leading) vane is much narrower than the inner (trailing) vane.
- Size
- Approximately 5-7 inches (13-18 cm) in length. This is consistent with the primary feathers of a medium-sized corvid with a total length of 18-24 inches.
- Rarity
- Common. They are abundant throughout their range and are frequently seen due to their social nature and bold behavior.

Description
This feather belongs to the Black-billed Magpie, a flamboyant member of the crow family known for its long tail and striking black-and-white plumage. The bird itself is roughly the size of a crow but appears longer due to its tiered tail. In flight, these white primary panels create a flickering effect. They are highly intelligent, social birds known for their complex vocalizations and opportunistic feeding habits.
Colour & Pattern
Striking bicolor pattern. The outer vane and the tip of the feather are deep iridescent black (which can show blue/green sheen in direct light). The inner vane features a large, crisp white patch that stops before reaching the apex. The ventral side is more matte in appearance.
Barb Structure
Mostly pennaceous and tightly interlocked for flight efficiency. The lower portion near the calamus shows some plumulaceous (downy) barbs for insulation. Barbules are intact with visible hooklets though there is some mechanical separation (split barbs) along the trailing edge.
Texture & Surface
Smooth and stiff. The black areas have a slight glossy sheen due to melanin saturation and structural microscopic layering, while the white area is matte and slightly softer to the touch.
Key Features
The most diagnostic feature is the 'magpie flash'—a crisp, large white area restricted to the inner vane of a dark primary flight feather. The combination of intense black melanin and pure white is unique in this size class in Western North America.
Habitat
Open woodlands, meadows, riparian thickets, and increasingly common in suburban gardens and farmsteads. They prefer areas with scattered trees for nesting and open ground for foraging.
Geographic Range
Western North America, ranging from coastal Alaska down through western Canada and the Western United States to northern New Mexico and Arizona.
Ecological Role
Omnivorous scavengers and predators. They play a vital role in cleaning up carrion and controlling insect populations, but they are also known for raiding the nests of other birds for eggs.
Similar Species
The Yellow-billed Magpie (Pica nuttalli) has nearly identical feathers, but is restricted to California. Crows and Ravens have entirely black primaries without the white patch. Some raptors have banded white, but not the solid blocky patch seen here.
Interesting Facts
Magpies are one of the few non-mammal species known to be able to recognize themselves in a mirror test. They are also known for 'funerals,' where a group will gather noisily around a deceased member of their species.
Condition Notes
Fair to Good. There is significant 'unzipping' or separation of the barbs along the trailing edge, likely due to mechanical wear or the bird's grooming/molting process. No obvious signs of parasite damage (lice holes) are visible.
