WHO COOKS FOR YOU?. WHO COOKS FOR YOU-ALL?. Barred Owls are known for this haunting, repetitious song, which is occasionally heard even during the day. Barred Owls are a common resident of swamps and wet forests in the eastern US and much of southern Canada. They have dark eyes (not the glaring, piercing, yellow eyes usually associated with owls and other birds of prey), which gives them a mysterious and sometimes quizzical appearance. This one was photographed in the Great Dismal Swamp, Virginia, USA. Photo taken with a Celestron 750mm f5.6 lens on Ektachrome 400 film. (Date: May 1978)

Burrowing Owls are common breeders in grasslands and prairies throughout the western US. There is also an isolated population in southern Florida. As the name implies, they live in burrows in the ground, which they either dig themselves or appropriate from rodents such as Prairie Dogs. They often live in close proximity to developed areas, such as golf courses and airfields. They are very diurnal, and can easily be seen standing near their burrows or hunting during the day. Photo taken with a Nikkor 300mm ED f4.5 lens on Kodachrome 64 film. Indeed, this one was photographed near a nest burrow in the infield of a local park's baseball field in the Florida Keys, USA.
