Listen to Burrowing Owls Hiss Like Rattlesnakes

These tiny desert dwellers use sound to warn away unwanted visitors.

The Burrowing Owl鈥檚 vocal abilities have raised eyebrows among birders and scientists alike. Because as well as its double hoots and other calls, the Burrowing Owl is known for another hair-raising sound: a long, rattling hiss.

Standing on almost comically long legs, this yellow-eyed owl is very active in daytime, and its hissing habit may have evolved to mimic the sibilant warning given by a cornered rattlesnake. This sonic threat of a venomous reptile could be just enough to warn away most unwanted visitors from the owl鈥檚 nest burrow. In , ground squirrels were nearly as alarmed by the Burrowing Owl鈥檚 hiss as they were by the recording of a real rattlesnake.

Despite its name, the Burrowing Owl doesn鈥檛 do much digging, though. Instead, it鈥檚 more of a squatter, nesting and roosting in vacant rodent burrows, often those of prairie dogs . . . until it鈥檚 time to eat. Not content with providing the Burrowing Owl鈥檚 accommodation, rodents鈥攅specially mice鈥攁lso provide lunch. Well, they are lunch鈥攚ith a side of large insects. After feasting the Burrowing Owl retires again to its mostly subterranean life.
