Northern Shrike

The Butcher Bird

1-3-14 impaled mouse & MS shrike by Bridie McGreavy DSC_0146The Northern Shrike (Lanius excubitor) is highly unusual in that it is a predatory songbird. Birds, mammals and insects are preferred over nectar, nuts and seeds. This tundra-nesting bird comes as far south as New England to overwinter, where it preys mainly on mice, voles and small birds. The Northern Shrike often kills more prey than it can immediately eat or feed its young, storing the excess food to eat later, when available living prey may be scarce. The manner in which it stores this extra food is what gave it the name “butcher bird;” it often impales prey on a thorn, broken branch (as in photograph) or even barbed wire, or it wedges prey into narrow V-shaped forks of branches, where they hang until reclaimed by the shrike.
