WEST SCRAMENTO REGION, CA (MPG) - This time of year, after the leaves have fallen from the willows, Great Horned Owls are easier to see during the day in the Yolo Bypass Wildlife Area. The Yolo Basin Foundation invites members of the public to join docents on a tour of the area on Saturday, February 10 from 9 a.m. to noon.

The mottled brown Great Horned Owls (Bubo virginianus) aim to blend into leafless trees. Their large silhouette of a thick body, wide head and prominent feathered ear tuffs can be spotted perched in the branches, generally near the trunk. Great Horned Owls hunt by night and eat a wide variety of prey including birds, mammals, fish and insects. Their size allows them to eat larger prey such as skunks, raptors and geese. Great Horned Owls, like most owls, eat much of their prey whole. The indigestible materials such as fur and bones are compacted into a pellet that owls eject through their mouth. Dissecting owl pellets can reveal recent meals. Other bird species seen this time of year include Western Meadowlarks, Marsh Wrens, American Bitterns, Buffleheads, Ruddy Ducks and Black-crowned Night Herons.

All interested tour participants should meet a few minutes before 9 a.m. in Parking Lot A of the Yolo Bypass Wildlife Area, at the west end of the Yolo Causeway.
