• Pin-Tailed Whydah "The species is a brood parasite which lays its eggs in the nests of estrildid finches, especially waxbills. Unlike the common cuckoo, it does not destroy the host's eggs. Typically, 2–4 eggs are added to those already present. The eggs of both the host and the whydah are white, although the whydah's are slightly larger. The nestling whydahs mimic the gape pattern of the fledglings of the host species.[7]
  
  The male pin-tailed whydah is territorial, and one male often has several females in his small group. He has an elaborate courtship flight display, which includes hovering over the female to display his tail. The song is given from a high perch, and consists of rapid squeaking and churring. The diet of this species consists of seeds and grain.[5][7]"
