Some birds practice brood paratisism - ie, they use the nests of parenting abilities of other birds to raise their young. In evolutionary terms this is an expensive practice, and more importantly, limits the ability of the parasite species to expand as they can only grow in accordance with the availability of the hosts nests ie they are always limited in numbers by the availability of hosts. From an evolutionary point of view, why then do these birds practice brood parasitism?
