Big Brother Eviction Cuckoo Style | Natural World | BBC Earth

A newborn cuckoo's instinct is to remove from its adopted nest any of the warbler's eggs. But more sinister is cuckoo's removal of the warbler's own newborn chick.

It's amazing how some birds like crows, owls, parrots are so smart they can solve puzzles and even some math problems, while there are birds that are so dumb that they literally can see their egg fall off, pushed by another chick and their reaction was like " . . . ".

[@cameronstarkel5629]

I was just reading that current studies show that the cuckoo mom will come back and check occasionally and if the foster mom isn't taking care of the chick, the cuckoo will destroy the nest and all the eggs, so the foster bird 'know better'. It's called the Mafia Theory.

This is not the case if the cuckoo egg is recognized. Some species of bird recognize the cuckoo egg and will remove it, thus saving their clutch of eggs from a cuckoo chick. Cuckoos, contrary to popular belief, do not come back to do anything about whether the parents remove or destroy the egg. This has not been documented to happen, once laid, the egg is at the mercy of the parents it was left at.

@@jedsteelwell2354 Cuckoos have been in an evolutionary arms race with the bird species they take advantage of, for a long, long time! They have evolved to be very secretive, being able to lay eggs (in other birds' nests) in only 10 seconds, and those eggs look remarkably like those of the birds they are fooling, even when the other birds have evolved distinctive patterns on their eggs. Put a different looking egg in the nest, most birds will reject it! The part which is less well understood, is why many bird species don't seem to recognise the giant cuckoo chick, is not their own! But the cuckoo chick is able to make a sound resembling a whole nest-full chicks, so that the 'parents' bring more food! (Sorry for the long reply, I just watched a lecture about it!).

It is worth noting though that most cuckoo species do not pull this nest switcheroo they actually just raise their own kids. Only a handful of them actually participate in this practice and they all under the same subspecies. But whatever, this is the species I think we're all fascinated. I will try to find some nest videos of cuckoos of slightly different varieties that do not engage in this. Curious what kind of parents they are

I thought the same thing. But then it dawned on me that having to spend numerous weeks feeding and caring for her chicks, she can go right off and lay another egg in another nest, and then a few days later lay another, and so on. Perhaps that’s the evolutionary strategy: to lay as many parasitic eggs as possible during the mating season. Maybe each year she can have dozens of offspring survive to carry on the cuckoo empire in this manner.

It goes against human nature to like cuckoo behavior. I do not like it either, but isn't it absolutely amazing how such behavior can be genetically coded and become a basic instinct in a newly hatched cuckoo? I do not think this instinct could ever develop on little step at a time. Adult cuckoos actually will return to the nest and puncture the other eggs with their beaks. Cow birds do very similar things to the nest that they lay their eggs in. It is amazing behavior regardless of what we think of it.

[@parkinfurkmaz2877]

Agreed, too many people are criticising an animal's behaviour because it doesn't conform to the social values the humans evolved to have. It is utterly insane to think that this trait evolved incrementally and embedded as an instinct, not learned. These cuckoos have no intended malice towards the other bird species; their urge to do what what they do is as powerful as our urge to breathe air.
