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.
