However, the female also exists as a rare rufous "hepatic" morph, so instead of being grey it is red-brown. The eyes and legs are yellow and the slightly curved bill is horn-coloured. In flight, the Cuckoo can be easily mistaken for a Sparrowhawk or Kestrel , because it has swept-back wings and long tail.
However, Sparrowhawks do not have pointed wings like the Cuckoo, and the Kestrel is streaked and not barred on the underparts. When perched, usually in the open at the top of a tree, the Cuckoo drops its wings below the level of its tail, as in the photograph. It also breeds throughout Asia east to Japan.
The earliest-ever reliable record of a cuckoo in England was one at Farnham in Surrey on 20 February It is traditional to write to The Times when you hear the first cuckoo of spring.
Only the male cuckoo calls cuckoo , and as the spring progresses the double-note tends to change: In June I change my tune. Cuckoo spit has nothing to do with cuckoos, but is produced by insects as a protection from predators. Each season a female will lay between 12 and 22 eggs, all in different nests. More than species have been parasitised by cuckoos in Europe: in Britain the most favoured species are dunnock, meadow pipit and reed bunting. A female cuckoo will generally lay her eggs in a nest belonging to the same species of bird that reared her.
Unlike most birds, female cuckoos lay their eggs in the afternoon rather than the morning. Young cuckoos do not tolerate other eggs or chicks in their nest. Adult cuckoos move back to Africa as soon as the breeding season is over — as early as the second half of June in southern England.
Young cuckoos follow their parents back to Africa several weeks later. The cuckoo spends nine months of the year in tropical Africa, where it has never been heard to sing.

Reed-warbler-specialist cuckoos lay a greenish spotted egg, just like those of reed warblers, while meadow-pipit-specialist cuckoos lay a brownish spotted egg, just like those of meadow pipits.
Both these hosts reject eggs unlike their own, so the specialised cuckoo-egg mimicry is essential to fool them. The female cuckoo also needs secrecy to succeed, because if the hosts see her at their nest they are alerted to inspect their clutch more closely. She glides down to the host nest from a hidden lookout perch, removes a host egg, lays her own in its place, and is off — all within a second visit. As she departs, she often gives a chuckle call, as if in triumph. This is perhaps the most remarkable trick of all.
So the female cuckoo has the last laugh as she flies away. 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. 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. What we witness is a fantastic arms race between parasite and host.
This titanic battle commences with that famous bird call. Perching motionless in a tree she will lay in wait, monitoring the nests of her potential victims. Her job done she zooms off, never to see her offspring again. The entire operation takes just 10 seconds.
But why does she have to be so quick? If the hosts are alerted to the presence of a cuckoo they are more suspicious of the eggs in their nest. But if they are unaware, they will incubate the interloper in blissful ignorance. They specialise in one species and pass the ability down to their young. The experiment also highlighted another aspect of this battle.
