(Phys.org) —A team of researchers in Spain has found that at least one species of cuckoo bird may actually help its nest-mates survive. In their paper published in the journal Science, the team describes how in studying the great spotted cuckoo, they found that crow hatchlings were actually more successful due to the presence of an uninvited bird.
