We all know Cuckoos as the harbingers of spring - whose haunting calls proclaim the birds own name across fields and reedbeds. Cuckoos are also well known, perhaps even infamous, for their habit of laying their own eggs into the nests of much smaller species, such as reed warblers, who are then doomed to raise the enormous cuckoo chick rather than their own young, and whose eggs are ruthlessly thrown from the nest by the cuckoo hatchling.But how does this complex behaviour act out in nature, and how did it evolve? A bird much more often heard than actually seen, and often mistaken for a hawk or falcon when briefly glimpsed in flight.
In this book the authors delve into the stories behind what we see, and into the complex and ever evolving What are the cuckoo's special tricks and what counter-measures have the host birds developed to resist the depredations of cuckoos?
