  • The northern hawk owl is distinguished by:
    • a lack of ear tufts
    • dark brown upper parts with white spotted wings
    • a speckled and streaked crown and hind neck
    • the white underside is finely barred with black
    • two darker patches are located on either side of the breast.
Distribution

Reproduction and Growth

Breeding Behavior

  • Nests are found in the cavities of trees and dead stumps.
  • Three to seven eggs are laid.
