The Diederik cuckoo parasitizes several weaver (especially the Village Weaver) and bishop species. Note the completely barred underwing in flight (upper, Rubondo, 3-13; 2nd row left, Kitulo NP, 3-11, both courtesy of Paul Oliver) and the red eye in the male, brown eye in the female. The 2nd row right photo is of a juvenile (Lengijavi, 1-12). The left 3rd row immature was at Nanja Dam, 6-06); the right 3rd row, Engikaret (2-23), courtesy of Per Holmen. The left lower bird (courtesy of Owen Evans) was trapped and died in the tubular entrance of a weaver's nest. The right lower adult male was seen at Shambarai (1-13); click it to see 17 enlargements.
