Quick Summary

Precocial young are animals that are capable of a high degree of independent activity shortly after birth or hatching. Unlike altricial young, which are born helpless and require extensive parental care, precocial animals are more developed at birth.12

Examples of precocial birds include ducks, geese, ostriches, pheasants, and quail. Their chicks typically have strong legs and are covered in down, allowing them to see and move around soon after hatching. Mammals like ungulates and guinea pigs are also considered precocial.12

This advanced state of development allows precocial young to walk independently and forage for themselves, though they may still rely on parental guidance for protection and to form attachments, a process known as imprinting.2

…move about at once (precocial), or they may be blind, hairless, and essentially helpless (altricial). In general, precocial young are born after a relatively long gestation period and in a small litter. Hares and many large grazing mammals bear precocial offspring. Rabbits, carnivores, and most rodents bear altricial young.
