Asymmetrical Ears

At last Saturday’s FMEL-ORCA conservation stewardship class, I talked about birds of prey including the Barred Owl (Strix varia) that I photographed on a local ranch . . . .
. . . . and the Great Horned Owl (Bubo virginianus) photographed at Pelican Island National Wildlife Refuge in the process of stealing an Osprey nest for its own use.
A question was asked about the hearing ability of Owls, which led me to discover that an Owl’s skull has the ears asymmetrically placed, which makes it easier for the Owl to locate the direction that sounds are emanating from. A neat evolutionary adaption that, when combined with the Owl’s acute vision, make these birds formidable hunters. You learn something new everyday!

  1. Incredible. It makes us think about the double eyed human vision, allowing us to see in 3D!
