Eastern Screech Owl
formerly Otus asio
River Journey - Ranger Rick's Backyard Safari gallery
Eastern screech owls are cavity nesters and both parents are active in rearing their three to five chicks (average clutch size). They have a symbiotic relationship with blind snakes. Sometimes they catch the snakes but do not eat them. Instead, the owls place the snakes in their nests where they survive by eating the insect larvae in the nest. According to some studies, this relationship creates a greater success rate for young owls to fledge. Left to its choice the Screech Owl is a good neighbor controlling the local mice population.
The IUCN listing for this species is Least Concern.
