Megascops asio
A stocky, short-tailed screech owl of eastern North America with grey and rufous morphs that adapts to wooded suburbs. It is among the heaviest screech owls, and birds have lived over 20 years in captivity.
The eastern screech owl (Megascops asio) is a stocky, short-tailed owl found widely across eastern North America from Mexico to Canada. Two colour morphs occur, grey and rufous, in proportions that differ sharply between subspecies and regions. Five subspecies are usually recognised, although the taxonomy within the species is described as muddled. It lives in most woodland types across its range and is comparatively tolerant of urban and developed areas, often living close to people yet seldom seen because it is strictly nocturnal. The primary song ends in a tremulous whinny, a terminal flourish that only the subspecies mccallii lacks. Birds have lived more than 20 years in captivity, though wild individuals rarely reach such an age.

Insects, small mammals and small birds in the wild; frozen mice, day-old chicks and quail in captivity
A cavity nester that takes readily to boxes - a study found fledging rates in boxes and natural cavities essentially the same. Provide cover it can hide in by day.
Strictly nocturnal, it hides in cavities or among branches by day. It tolerates urban surroundings but in captivity prefers a quiet location.
The primary song ends in a tremulous whinny, a terminal element absent only in the subspecies mccallii, and it is repeated through the night.
Listed on CITES Appendix II, so import requires an export permit. Frozen mice, chicks and quail are thawed for feeding, and a steady supply of raptor food is a precondition for keeping the bird.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Eastern Screech Owl is Over 20 years has been recorded in captivity, though wild birds seldom live that long. With proper care and nutrition, they can live a long and healthy life.
Eastern Screech Owl typically reaches 16-25cm (121-244g) as an adult. Size may vary depending on care conditions and individual genetics.
