Cuckoo (a kind of cuckoo bird - ed) is a parasitic bird. That is, this bird used to smuggle her into the nest eggs of other birds that are hatched without the knowledge of the owner of the nest.
Well, to be able to freely access the nests of other birds, in this case the bird reed warblers, cuckoo usually act like a bird sparrow hawk aka European eagle eating a smaller bird.
The cuckoo does have a visual similarity to the bird sparrow hawk. "The most striking similarity of the cuckoo bird sparrow hawk is a stripe pattern on their bellies," said Justin Welbergren, researchers from the University of Cambridge in England, as quoted from the BBC website.
Therefore, the cuckoo's use of his physical resemblance to terrorize and drive out the birds that escaped from reed warbler nests. "If the body does not like the cuckoo hawk, like the cuckoo will be surrounded by reed warbler, when approaching their nests," said Welbergen.
When 'intervene' reed warbler nests, the cuckoo will lay her eggs in the nest freely. Having gone cuckoo, bird reed warbler egg with no suspicion would have thought it was hers and menetaskannya eggs.
Even until the eggs had hatched cuckoo, reed warbler birds will still feed him, because he thinks it is his son. A recent study also found that the cuckoo was singing like a bird newly hatched reed warbler. source vivanews.com
