While primarily associated with mature forests, they may also be found in partially cleared areas with sufficient tree cover. Their distribution is patchy and often tied to specific habitat requirements.

Occasional reports of vagrant individuals have been recorded in the southern US, including the first recorded sighting in Texas in 1996 at Bentsen-Rio Grande Valley State Park.

Distribution Map

This map gives you a rough idea of where you might spot a Stygian Owl. The coloured areas show countries where these birds have been seen.

A few things to keep in mind:

  • Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
  • Where birds live can change with seasons and available food
  • This map is quite simple - it doesn't show exact locations

We're working on making our maps even better! Soon, we hope to show you:

  • More detailed maps for bigger countries, including state and region
  • How birds move around during different seasons
