The Eastern Screech Owl is relatively common species of owl that lives in parts of eastern North America. They are small, measuring 10 inches long at most, and weighing no more than 10 ounces.
Eastern Screech Owls have proportionally large heads with ear tufts, short tails, and a stocky body shape. Eastern Screech Owls have a mottled plumage that comes in two distinct color morphs, referred to as red phase and gray phase.
Eastern Screech Owls are nocturnal and will roost in tree trunks or cavities during the day. Despite their name, their call is a descending, soft whinny.
Conservation
The Eastern Screech-Owl is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
