About This Species

Found in open country, farmland and scrub from the southern United States through Central America, often seen walking on the ground near livestock or in mixed flocks with other blackbirds. Breeding males perform a distinctive hover display above females, ruffling their neck feathers, which is a good behavioural cue for identification in spring and summer. Its striking red eye is visible at close range in good light.

Ethical Viewing Guidelines

  • A few metres' distance from a foraging flock is generally enough not to disturb feeding behaviour.
  • As a brood parasite that lays eggs in other birds' nests, it receives standard wild bird protections under national and regional laws such as the US Migratory Bird Treaty Act, though enforcement and specific provisions vary by country.
  • Because it targets host nests, avoid drawing attention to any nest, host or parasitised, by lingering nearby.
