Hawk/goose effect
In cognitive ethology, the hawk/goose effect refers to a behavior observed in some young birds when another bird flies above them: if the flying bird is a goose, the young bird shows no reaction, but if the flying bird is a hawk, the young bird leans itself in order to reduce the danger. Initially thought to be an inborn instinct developed from natural selection, it was later shown to be cultural. It was first observed by Konrad Lorenz and Nikolaas Tinbergen.[1][2][3][4]
