Owls 猫头鹰

by Jerri Graham

As Harry Potter's beloved pet, Hedwig, a Snowy owl, is probably the most famous bird in the world. Snowy owls are just one of the more than 200 species of owls. Owls _(1)_ size and can be as little as the 31-gram Elf owl and as large as the Blakiston's Fish Owl, which can weigh almost five kilograms. Owls are actually very different from other birds.

Owls are nocturnal animals, which means that they sleep during the day and hunt at night. They are known both for their unique call, or hoot, and their extremely good sight. They use these features to navigate and hunt in the dark. They are far-sighted and use this vision to track and target their prey _(2)_ a distance.

_(3)_ pigeons and sparrows can exist on seeds and grains, this would not satisfy most owls. Instead, they prefer to eat small mammals such as moles, mice, and rabbits. _(4)_ these warm-blooded creatures, they will also feed on insects and other birds when hunger strikes. Like other birds of prey, owls have sharp beaks and claws that they use to tear their food to pieces before eating it.

Sometimes they do swallow larger chunks of bone, feathers, and other things that are indigestible. What their bodies don't digest is thrown up _(5)_ owl pellets. These lumps of bone and other bits are collected because they are _(6)_ for studying the habits and diet of owls.

Owls serve man by _(7)_ some of the pests that would make life unbearable. Protecting their habitat is, in a sense, a way of protecting our own.
