Description
A medium-sized all-black passerine with a heavy bill and broad wings. Known for their social intelligence, 'caw' vocalizations, and communal roosting behaviors.
Colour & Pattern
Uniformly iridescent black with subtle violet or blue-green sheen visible under direct light; the rachis is dark charcoal to light gray at the base
Barb Structure
Pennaceous at the distal end (stiff and interlocked); plumulaceous (downy) at the proximal base near the calamus for thermoregulation
Texture & Surface
Smooth and glossy on the pennaceous portion (water-repellent); soft, fuzzy, and matte on the plumulaceous portion near the skin
Key Features
Solid black coloration with iridescent sheen; lack of banding; large proportion of downy fluff (afterfeather) at the base of the rachis
Habitat
Highly adaptable; found in open woodlands, agricultural fields, urban parks, suburban yards, and landfills
Geographic Range
Year-round resident across most of North America from southern Canada to northern Mexico
Ecological Role
Omnivorous scavenger and predator; plays a vital role in cleaning carrion and controlling insect/rodent populations

Interesting Facts
