Taxonomy

This and almost all Screech-Owls in the Americas have previously been considered to belong in the same genus (Otus) as the European and Asian Scops-Owls, but a reassignment to Megascops has been accepted by among other authorities, the American Ornithologists' Union.

Subspecies

There are 6 subspecies1:

  • M. a. maxwelliae:
  • South-central Canada and north-central US
  • M. a. naevius:
  • M. a. asio:
  • M. a. hasbroucki:
  • Central Oklahoma to Texas
  • M. a. floridanus:
  • M. a. mccallii: (McCall's):
  • Southern Texas to north-eastern Mexico (Nuevo Le¢n and Tamaulipas)

Habitat

Their main habitat is open deciduous or mixed woodland and forest edges.

Behaviour

Usually solitary. Nocturnal; using tree cavities for the day roost.

Breeding

They nest in a natural tree cavity or a woodpecker hole. They are also known to make use of nest boxes. They are strictly nocturnal, roosting during the day in cavities or next to tree trunks.

Diet

They swoop on prey from a perch on a lower tree branch or take insects in flight. Their diet consists of large insects, small rodents and small birds. They have excellent hearing and night vision to find their prey.
