Conservationists at the Royal Society for the Protection of Birds (RSPB) have been using remote controlled drones to watch the nests of endangered breeds and monitor the progress of reintroduced species. Over time, it’s these physiological changes that can disrupt animals’ breeding or rearing habits.

Most birds will follow a set group of behaviours, building a nest a certain way, courting a certain way, eating a certain set of food. But birds have a certain amount of flexibility buil in as well, which is very apparent in some of the smarter birds, like crows and parrots, but can still be present in other birds too.

Plastic behaviors are not automatically unrelated to natural selection, but the way those behaviors vary across individuals or across groups may not be best explained by underlying genetic differences. Changes in antipredatory behaviour in captivity have been proposed to explain the higher invasiveness of wild-caught exotic species.
