I’m your host, Kate Shaw. This week we’re going to learn about two tiny owls. Thanks to Elizabeth and Alexandra for their owl suggestions! The burrowing owl is native to the Americas, especially the western part of North America, and most of Central and South America. It prefers grasslands and other open areas. It’s a small owl, not much bigger than the average songbird. It’s mostly brown with lighter underparts that are barred with a brown pattern. You can tell a lot about an owl by the color of its eyes. In general, an owl with dark eyes is most active at night, an owl with orange or red eyes is likely to be most active at dawn and dusk, and an owl with yellow eyes is often active in the day. That’s not a hard and fast rule, but it can help you make a good guess about an owl’s behavior. The burrowing owl has yellow eyes, and it is indeed active in the day. The term for daytime activity is diurnal. In past episodes I’ve said that owls have long legs that are usually hidden by feathers. In the case of the burrowing owl, its long legs are in plain sight because it spends a lot of the time running around on the ground. It will sometimes chase prey on foot, but other times it will perch on a fence post, tree branch, or some other high place to watch for a small animal to pass by. Then it will swoop down to grab it just like any other owl. It eats mice and other small rodents, lizards, small snakes, frogs, large insects and other invertebrates like scorpions and caterpillars, and birds. It especially likes termites and grasshoppers. Females are more likely to hunt during the daytime, while males are more likely to hunt at night or at dawn and dusk. Sometimes the burrowing owl will eat fruit and seeds too. When the burrowing owl has more food than it can eat, it will store some in underground larders. The burrowing owl gets its name because it builds a nest in a burrow in the ground, often in burrows dug by other animals like prairie dogs and skunks. Some subspecies of burrowing owl will dig its own burrow, and all subspecies will enlarge an existing burrow until it’s happy with the size. It uses its beak to dig and kicks the dirt out with its feet. Both the male and female will work on the burrow together. Once it’s the right size and shape, the owl will bring in dried grass and other materials to line the burrow. One of its favorite materials is dried animal dung, especially from cattle. The dung releases moisture inside the burrow, making it more comfortable, and attracts insects that the owls eat. Win-win! It will also scatter animal dung around the entrance of its burrow and will sometimes also collect trash like bottle caps and pieces of foil to decorate the entrance. The female lays her eggs in the burrow and spends most of her time incubating the eggs, only going outside briefly to stretch her legs. The male stands guard at the entrance to the burrow or nearby except when he’s out hunting. He brings food back for the female. When the eggs hatch, both parents take care of the babies. At first the chicks stay in the burrow, but as they grow older they come out to play outside and start learning how to fly. Since burrowing owls usually nest in small colonies, there’s always an adult watching for danger somewhere nearby. Most birds abandon their nests after their chicks are grown. The burrowing owl often uses its burrow year-round, although populations that migrate will usually make a new burrow when they return to their summer range. The burrow gives the owls a place to nap during the hottest part o...
