Even urban and suburban sites withscattered trees harbor screech-owls. The easiest wayto find them is to venture out on clear nights, andlisten. Judicious playing of their songs – or imitatingthem if you are a good whistler – frequently provokesa response.While they might turn up nearly anywhere, anideal habitat is young or semi-open woods, preferablywith a stream nearby. In such places, two or threeowls might be heard calling simultaneously.It always pays to take a good look at tree cavitiesduring the day.

Great horned owlBubo virginianus (Bew-bo [eagle owl] ver-jin-ee-ain-us [of Virginia; location of first specimen])TRACKS18-24C O M M O N O W L S O F O H I O 25An 1890 quote from famed naturalist Ernest Thompson Setonsums up this owl well: “…their untamable ferocity… magnificentbearing… strictly carnivorous tastes… would make me rank thesewinged tigers among the most pronounced and savage of the birdsof prey.”These powerful predators are near the top of the avian foodchain, and one of their colloquial names, “cat owl,” is an indicationof the size of prey that they can take. The great horned owl is thesecond most common Ohio owl, after the Eastern screech-owl.They occur across the length of North America, to the limit oftrees where the tundra begins in the north, and south throughCentral America and into South America. At least 16 subspecieshave been described, and plumage variations among thesesubspecies follow Gloger’s Rule: the darkest populations occurin the most humid areas. Great horned owl and snowy owl arethe only members of the genus Bubo in the Western Hemisphere;about a dozen other species are found in Africa and Eurasia.D e s cripti o n great horned owlLength = 22 inchesWingspan = 44 inchesWeight = 3.1 lb.This is our largest resident owl, and great horned owls appearvery powerful and thick-bodied. They are our only large owl withprominent ear tufts; the next largest tufted owl is the long-eared owl,which is five times lighter and about 1/3rd smaller overall. Longearedowls are generally much scarcer, only likely to occur from latefall through early spring, and are quite secretive and seldom vocalizeAdult great horned owlPhoto by: ODNR Division of Wildlife / Tim Daniel
