Chickens remember the faces of other birds and can recognise individual flock members.

The longer version

Domestic fowl are more perceptive than their reputation suggests. They discriminate between individuals using features of the face and comb, and they retain that information long enough to keep track of flock mates over time.

This ability supports a social system built on a pecking order, where knowing who has already been challenged saves a great deal of pointless conflict. Chickens also form preferences for particular companions, recognise familiar humans, and can learn by watching others solve a problem. Their communication is elaborate too, with distinct calls for food, alarm and aerial versus ground threats. Such complexity is typical of social birds, where tracking relationships is as important as finding food.
