It's hard to know precisely when the red-winged blackbird, Agelaius phoeniceus, is about to attack. The birds tend to swoop in, hitting victims from behind. Sometimes, the birds take turns attacking victims. It's unclear, however, if the red wing attacks from its beak, which is usually sharp and cone-like, or with its feet.
Para quem pudesse pensar que eu estava a inventar. Se bem que o meu não era red winged.
