Do birds reuse nests?

Eric has given you the best answer, that most birds do not reuse their nests. Many birds reuse some of the nesting material from old nests (not necessarily from their nest) while making their new nest. Some storks (White stork) and eagles reuse their nests. read more

Many birds will reuse old nests, particularly if the nests were successful in the previous years. Some birds will occasionally seek refuge in the nest throughout the winter and then come spring they will clean and spruce up the nest to prepare for offspring. read more

Depends on the species..a few do re-use nests, but MOST do not. Nests get parasites, and basically get "dirty" and most birds will build a new nest for each brood. Some birds might take nest material from an old nest to build a new one as well..so you should just leave it in case it will be used again in some form. read more
