Quick Summary

The term nidicolous in zoology describes animals, particularly birds, that are reared for a time in a nest. This means they remain in the nest after hatching and require care from their parents for a period before they are able to become independent.12

The word originates from the Latin word nidus, meaning "nest," combined with the English form "-colous," indicating living in or on something. This contrasts with nidifugous animals, which leave the nest shortly after hatching. While all nidifugous animals are precocial (capable of independent activity soon after hatching), some nidicolous animals can also be precocial, meaning they can leave the nest but choose to stay. Other nidicolous animals are altricial, meaning they are born helpless and require extended parental care.12
