Pretend for a second that you have no idea what a bird is. You know what beaks, feathers, wings, etc. are, but you don’t know what a bird is.
Now read the following:
Birds (class Aves or clade Avialae) are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates.
Modern birds are characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Extant birds have more or less developed wings; the most recent species without wings was the moa, which is generally considered to have become extinct in the 16th century. Wings are evolved forelimbs, and most bird species can fly.
Birds are social, communicating with visual signals, calls, and songs, and participating in such social behaviours as cooperative breeding and hunting, flocking, and mobbing of predators.
These are all from Wiki’s page on birds. You can’t tell me that from these descriptors that birds don’t sound fucking terrifying.
TOOTHLESS-BEAKED PREDATOR-MOBBING DEATH-BOMBS FROM ABOVE!
Okay, I’m done. Back to studying.
