Cuckoos stay on course
With short hectic wing strokes that are hardly raised above the body, the flight of the cuckoo is not the height of elegance. Nevertheless, their wings carry them over 16,000 kilometres a year. Martin Wikelski ...
Cuckoos impersonate hawks by matching their 'outfits'

New Zealand's unique biodiversity has been strengthened with the identification of a new endemic songbird family—the family Mohouidae—which includes the endangered Yellowhead, the Whitehead and the Brown ...
Scientists get bird's-eye view of how cuckoos fool their hosts (w/ Video)
Using field experiments in Africa and a new computer model that gives them a bird's eye view of the world, Cambridge scientists have discovered how a bird decides whether or not a cuckoo has laid an egg in ...
Honeyguide birds destroy own species' eggs to eliminate competition
Like cuckoos, honeyguides are parasitic birds that lay their eggs in other birds' nests and dupe them into raising their young. Now scientists reveal that, unlike in cuckoos, the resemblance between honeyguide ...
