Why cuckoo calls sometimes sound differently and what it means

Cuckoos can change the structure of their voice and song due to various factors. New experiments show that the modified version of the cuckoo call draws less attention from other cuckoos than the classic 'cuckoo'. This may mean that males with impaired song are at a disadvantage when competing for females and territory.
