Typical Owls (Strigidae)

Short-eared Owl (Asio flammeus) - HBW 5, p. 241

French: Hibou des marais German: Sumpfohreule Spanish: Búho Campestre

Taxonomy: Strix Flammea Pontoppidan, 1763, Denmark.
Morphologically similar to A. otus, but recent studies of proteins indicate unusually large genetic distance between them. Sometimes thought to be closely related to A. capensis, which replaces it ecologically in Africa, but resemblance seems superficial and probably due to convergence, and vocalizations very different. Much darker race galapagoensis possibly specifically distinct. Race domingensis was formerly considered a separate species, including portoricensis as a race; alternatively, these two have been considered a single race of present species. Ten..

Much darker race galapagoensis possibly specifically distinct.

Ten subspecies recognized.

  • flammeus (Pontoppidan, 1763) - breeds Iceland, British Is, and locally through Europe and Asia E to Kamchatka and Commander Is, S to Spain, Caucasus, NE Mongolia and NE China; also North America from W & N Alaska through Canada and S to C USA.
  • ponapensis Mayr, 1933 - Pohnpei I, in E Caroline Is.
