The Burrowing Owl鈥檚 vocal abilities have raised eyebrows among birders and scientists alike.聽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.

听滨苍 , 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聽Burrowing Owl retires again to its mostly subterranean life.
