This bird, a species of cuckoo, can be difficult to see and photograph due to its habit of skulking in shubbery, undergrowth and dense waterside vegetation. It has a wide diet consisting mostly of insects, but it will also take young birds and eggs. The males construct a nest, they then incubate the eggs and provide most of the feeding and care for the young.
Seen at Nairobi National Park
The bird in the last photo may be the same one but I can't be sure as it was so far away. Also see: http://ibc.lynxeds.com/species/white-bro...
