The emphatic hoots of a pair of Barred Owls resonate in the still of a February night. So-called for the stripes on their breast, Barred Owls are among the largest owls in North America. They're also the most vocal. Their signature hooting sequence has been memorably described as 鈥渨ho-cooks-for-you?! who-cooks-for-you-all?!鈥
But this is just one of more than a dozen Barred Owl calls, ranging from a 鈥渟iren call鈥 to a 鈥渨ail鈥 to a wonderfully entertaining 鈥渕onkey call.鈥
Although the Barred Owl鈥檚 calls have long been heard in Eastern forests, it is a relative newcomer to the western US. During the 20th Century, its breeding range has expanded into the North and the West, and down as far as northern California.
The exact reasons behind the expansion aren't certain. But new riparian forests, fire suppression, and the planting of shelter-belts in the northern Great Plains are some of the human impacts that have likely played a role.
No matter what accounts for the Barred Owl鈥檚 dramatic sweep across the continent, the bird 鈥 and its extraordinary voice 鈥 seem here to stay.
