Description
This feather belongs to the iconic Northern Cardinal. Males are famous for their brilliant red plumage and black face masks, while females exhibit more olive-brown tones with red accents. This specific feather's muted red color suggests it is from a female or an immature male starting to molt.
Colour & Pattern
Rich, warm reddish-brown to dull crimson. Lacks strong banding or iridescence. The color is derived from carotenoid pigments. The calamus is semi-translucent.
Barb Structure
Pennaceous on the distal half with interlocked barbs; plumulaceous (downy) at the proximal base for insulation; barbs appear somewhat frayed at the edges.
Texture & Surface
Smooth and soft texture with a matte finish. Light and airy, typical of a songbird's insulating body plumage.
Key Features
Rich red-brown coloration, small size under 3 inches, and the distinctive transition from a downy base to a solid pennaceous tip.
Habitat
Found in woodlands, gardens, shrublands, and suburban backyards; prefers dense undergrowth for nesting.
Geographic Range
Common across Eastern and Central North America, from Southern Canada through the US and into Mexico and Central America.
Ecological Role
Seed disperser and insectivore; serves as a common prey species for hawks and domestic cats. Population is stable and expanding north.
Similar Species
Summer Tanager (more uniform bright red), House Finch (streaked patterns), or Pyrrhuloxia (grayer with red highlights).
Interesting Facts
Unlike many songbirds, both male and female Northern Cardinals sing. They are the state bird of seven US states, more than any other bird.
Condition Notes
Fair condition; showing moderate wear and separation of the barbs (venting) along the left edge; likely a naturally molted feather.
