§ Quick facts
§ Encyclopedia
The eastern screech owl or eastern screech-owl is a stocky, short-tailed owl that is relatively common in Eastern North America, from Mexico to Canada. Mid-sized for a screech owl, the species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls. Although it often lives in close proximity to humans, the eastern screech owl frequently avoids detection due to its strictly nocturnal habits.
