One may also ask, are parrots Altricial? Parrots have evolved their way into the best of both worlds.

In this way, what is the difference between precocial and Altricial?

In biology, precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. The opposite developmental strategy is called “altricial“, where the young are born or hatched helpless. These categories form a continuum, without distinct gaps between them.

Are chickens precocial or Altricial?
