Revision as of 01:08, 20 July 2014 by Njlarsen (talk | contribs) (remove {{incomplete}})

Alternative name: Guatemalan Screech Owl

Megascops guatemalae

Otus guatemalae

Identification

Includes both greyish and reddish morphs. Generally boldly patterened, including a row of white spots across shoulder. Underside paler than upperside but with black shaft streaks and cross markings. Wings do not reach beyond tip of tail. Eyes orange-yellow, bill greenish.

Similar species

Distinguished from Vermiculated Screech Owl by having less vermiculations, longer tail, and by legs being feathered to toes.

Distribution

Widely distributed from northern Mexico to Nicaragua and probably to northern Costa Rica[2]

Taxonomy

Seven subspecies are currently recognized[1]:

  • M. g. tomlini
  • M. g. hastatus
  • M. g. cassini
  • M. g. fuscus
  • M. g. thompsoni
  • M. g. guatemalae
  • M. g. dacrysistactus

This taxon used to include Vermiculated Screech Owl, split mainly based on analysis of vocalization.

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 have been accepted by among other authorities, the American Ornithologists' Union.

Habitat

Lowland to mid elevation in both humid and dryer forests and woodland.

Behaviour

Nocturnal, usually hiding in tree cavities or among branches with high leaf cover.

Food is mainly invertebrates with some small vertebrates taken.
