lynxloveschamois In the 18th century, Edward Jenner first recorded a newly hatched cuckoo’s murderous rampage. Puzzled by the migratory cuckoo’s parasitical existence, he suggested that the adult birds simply didn’t have time to raise their young, needing to nip back to Africa as soon as possible. Around the same time, the famed naturalist Gilbert White guessed that the cuckoo’s substantial stomach meant that it couldn’t incubate its eggs. To White, the desertion of the eggs was a “monstrous outrage on maternal affection”. But it was Charles Darwin who cut to the chase in 1859’s On the Origin of Species. He identified the immense benefit of being a brood parasite. Freed from parental duties, the cuckoo was able to lay many more eggs than its victims. However, Darwin’s observation prompts one question: if the cuckoo’s con is so effective, why aren’t more birds at it? Of all of British birds, only the common cuckoo (Cuculus canorus) goes to such extraordinary lengths, and worldwide only around 1 percent of all birds share its methods.

After 23 years studying the cuckoo’s sinister plans in Wicken Fen, Britain’s foremost expert on cuckoo behaviour, Dr Nicholas Davies of the University of Cambridge, is able to shed some light on the matter. “Foisting your parental duties on somebody else may seem to be a wonderful thing to do,” he explains. “But over evolutionary time, the hosts fight back so that the poor cuckoo has to work incredibly hard to be lazy, simply because it has to overcome all of these defences. What we witness is a fantastic arms race between parasite and host.” This titanic battle commences with that famous bird call. In May, the blue-grey male cuckoo arrives on our shores from Africa and booms out his distinctive ‘cuc-coo’, thereby establishing himself as God’s gift to the slightly browner female. Nature takes its course and the female’s work begins.
