Bear River MBR, a safe haven for migrating birds

BEAR RIVER MIGRATORY BIRD REFUGE — This 80,000 acres bird sanctuary lies in northern Utah, where the Bear River flows in a U-shape course through Utah, Wyoming, Idaho and back into Utah. It is the largest river in North America that does not ultimately reach the sea.

Bear River Migratory Bird Refuge (MBR) protects the marshes found at the mouth of the Bear River, providing a critical habitat for migrating birds. More than 250 species move through this area annually by the millions to rest and feed, including burrowing owls. The Bear River is the largest tributary of the Great Salt Lake, draining a mountainous area and farming valleys northeast of the lake and southeast of the Snake River Plain.

Burrowing owls can be found in open landscapes in both North and South America where they rest in burrows that were excavated by digging animals such as prairie dogs.
According to Wikipedia, burrowing owls are active during daylight but do most of their hunting from dusk until dawn when they can use their night vision and hearing to their advantage. Living in open grasslands as opposed to the forest, the burrowing owl has developed longer legs, which enables it to sprint as well as fly when hunting.
