摘要

人们曾多次观察到鸦科鸟类将硬壳食物放在路面上，当汽车驶过压碎硬壳时，鸦科鸟类就会吃掉露出的食物。然而，对于乌鸦是否有意做出这种行为一直存在争议。我们观察到一只美洲乌鸦（Corvus brachyrhynchos）将双壳类动物放在路面上，然后食用外壳被碾压后露出的肉。

American Crow Cracks Open Bivalve via Automobile

here have been many observations of corvids placing a hard-shelled food item onto a roadway, then consuming the food exposed when a passing automobile crushes the shell. However, it has been debated whether corvids perform this behavior intentionally. Our observation of an American Crow (Corvus brachyrhynchos) placing a bivalve on a road, then eating the meat exposed when the shell was run over, supports the idea that corvids intentionally use cars to crack shelled foods.
