  • The northern shrike: songbird like no other | Geophysical Institute
    Northern shrikes often jam their prey in forks of trees, or impale voles and birds on a sharp branch, or maybe a strand of barbed wire Shrikes may store food like this because their feet are more like a chickadee’s than a hawk’s; sticking their food to something helps them tear into it
