Our two female barred owls, Blanche and Rose, live along the Meadow Path from the upper parking lot to the main entrance and Sundial Plaza. Both barred owls are females and able to fly. One is missing an eye, and the other has a detached retina, which is why these raptors cannot survive in the wild.
Owls are stealthy hunters that usually are active at night. They have distinctive disc-shaped faces with large eyes and short, curved beaks. After eating, owls regurgitate pellets of fur, bone, and whatever else they cannot digest. These pellets make it easy for scientists to track what individual owls are eating -- pellets are collected, sterilized and taken apart to identify prey. Owls species are found living on every continent except Antarctica and vary greatly in size by species.
Owls have many adaptations that make them well-suited to being nocturnal hunters. They have serrated edges on their flight feathers that let them fly silently and sneak up on prey. Their facial disc helps funnel sound to their ears, and their skull is asymmetrical, which allows them to locate prey by timing differences. Their feathery ear tufts aren’t for hearing. They use them for display and camouflage. Owls have well developed eyes to see well at night, but their eyes face forward and they must turn their heads to see around them. Luckily, owls can turn their heads nearly all the way around (270 degrees out of 360!) and almost upside-down. This is because they have 14 vertebrae in their long necks. (Humans have 7.)
The barred owl, is a medium-sized owl. It is grey-brown with horizontal white streaks on its chest and vertical streaks on its stomach. These streaks, which look like bars, give them their name. The barred owl has a classic owl "hoot" that is often translated by humans as sounding like: "who cooks for you?." Nesting pairs mate for life and, like other owls, often make use of nests left by other birds. Barred owls have been observed wading for crayfish, which can turn their belly feathers a light pink. Their only natural enemy is the great horned owl. They live up to 10 years, but as long as 25 in captivity. Barred owls are found in moist forests, wooded swamps, and woodlands near waterways throughout the eastern half of the United States. They are sometimes also found in the Northwest.
