Box brood

from Wikipedia, the free encyclopedia

The nesting (or nesting ) is an ornithological technical term; there is a temporal overlap between two broods of a bird species. Since only the females lay eggs, it is always the nested broods of a female. While one brood has not yet fledged, the female mates again, lays eggs and begins to breed again. The first brood is brought up by the male alone . The male of the second brood can be the one of the first brood, but also another male. Both are observed in barn owls. A prerequisite for a successful nesting of the broods is a very cheap food supply, which is why brood nesting is also often observed in owls during so-called mouse gradations .

Furthermore, box brood occurs in wild pigeons ( e.g. wood pigeon ), kingfishers and others.
