Discussion The Northern Shrike sits quietly, often in the top of a tree, before swooping down after insects, mice, and small birds. It kills more than it can eat, impaling the prey on a thorn or wedging it in a forked twig. On lean days it feeds from its larder. Like other northern birds that depend on rodent populations, the Northern Shrike's movements are cyclical, becoming more abundant in the United States when northern rodent populations are low. Sometimes they hunt from an open perch, where they sit motionless until prey appears; at other times, they hover in the air, ready to pounce on anything that moves.
