Cuckoo, warbler images
The shining bronze cuckoo (Chrysococcyx lucidus) and the much larger long-tailed cuckoo (Eudynamys taitensis) lay their eggs in the nests of New Zealand native birds, including yellowheads (Mohoua ochrocephala) and grey warblers (Gerygone igata). Here you can see an image of a grey warbler and of each cuckoo. Photos by Dr Michael Anderson (Massey University), All rights reserved.
Dr Michael Anderson (Institute of Natural and Mathematical Sciences) recorded these calls as part of his research into the behaviour of shining cuckoos. You can learn more about Dr Anderson's work from his Radio New Zealand National interviews.
