Osteology and DNA sequence data, though, suggests that the burrowing owl is a terrestrial member of the little owls genus (Athene), thus it is placed in that group today, by most authorities. A considerable number of subspecies have been described, though they differ little in appearance; the taxonomic validity of several is still up-for-debate ...
Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn owl and bay owl family, Tytonidae.

Forest and spotted owl management documents often state that severe wildfire is a cause of recent declines in populations of spotted owls, and that mixed-severity fires (5–70% of burned area in high-severity patches, with >75% mortality of dominant vegetation) pose a primary threat to spotted owl population viability, but a systematic review ...
