1. Referring to birds that are hatched naked, blind, and too weak to stand or to feed themselves; thus remaining confined to their nests during their maturations: Nidicolous songsters usually stay in their dwelling until they are fully grown or close to being capable of flying.

Since meadowlarks are hatched helpless, blind, and without any feathers; they are obviously nidicolous animals that need to be taken care of by their parents.

Other nidicolous animals include mammals and marsupials (kangaroos, wallabies, koala, possums, wombats, etc.).

2. Living in the nests of other species or creatures: There is no doubt that there are nidicolous mites and other vermin that exist in the nests with the warblers.

Some nidicolous avifauna share nests with others of their species.
