Brief Description

A large, intelligent, all-black bird with a thick neck and a heavy bill. Crows are highly social, often forming massive winter roosts and exhibiting complex problem-solving skills.

Additional Information

  • Region of Origin: North America from southern Canada through the United States to northern Mexico.
  • Typical Sighting Period: Year-round resident throughout most of its range.
  • Plumage Details: Entirely black with an iridescent violet or blue-green sheen in direct sunlight. Juveniles are similar but have duller brownish-black feathers and blue or gray eyes that turn brown with age.
  • Ecological Significance: Acts as a primary scavenger (sanitation) and seed disperser; also serves as a sentinel, alerting other animals to the presence of predators like hawks and owls.
  • Conservation Status: Least Concern (IUCN); population is stable and adaptable to urban environments.
  • Observation Tips: Crows are easily spotted in open areas and suburbs. Look for them on the ground foraging or in large groups called 'murders.' They are wary and will fly away if approached too quickly.
