Habitat Management Series for Unique or Endangered Species. Report Number 11: Burrowing Owl, 'Speotyto cunicularia hypugaea'

摘要

The burrowing owl (Speotyto cunicularia) breeds as far north as southern Canada, from interior British Columbia east to south-central Manitoka and as far south as central Mexico. The eastern limit of breeding lies roughly along a line from Manitoka to northwest Louisiana. The winter range includes the southern portion of the breeding range, especially Texas, southern Louisiana and Mississippi, and western Florida, and extends south through central Mexico and western Central America to western Panama. Burrowing owls populations are declining in some areas due to loss of burrow sites resulting from burrowing mammal control activities, and from loss of habitat due to urban industrial and agricultural expansion.
