Great Gray Shrike Lanius excubitor

Thrush-sized bird; pale gray overall with black mask. In flight, watch for white patches in the wings. In areas of overlap, compare with other gray shrikes. Inhabits open habitats with scattered vegetation, from open forests to bogs and brushy meadows. Often seen on prominent perches, including power lines and short treetops, that offer perfect vantages for from which to spot prey. Carnivorous habits make shrikes unique among passerines, feeding on rodents and small birds. Vocalizations include bright short liquid trills and “gargling” phrases, often strung together into a repetitive song.
