THE INDIAN PIED CRESTED CUCKOO.

This Cuckoo has a most extraordinary range. It is found all over India and Northern Burma and is also found over a great part of Southern Africa.
Many oviduct eggs of Indian birds have been taken, and all of these are alike, deep blue egga, generally broad ovals or spheroidal in shape and almost identically like those of the foster parents, which are invariably species of the genera Argya and Turdoides. In size they agree well with the eggs of the latter but are, of course, much bigger than the eggs of some species of the former.
It is of course impossible very often to distinguish between the eggs of this Cuckoo and those of Hierococcyx varius, but over most of its range the latter breeds in April, May and June and the former in June, July and August. The eggs of the Hawk-Cuckoo are also larger on the average and are more broad elliptical rather than spherical. The yolk of the eggs of Hierococcyx is much paler than that of the egg of Clamator.
In the hills when this Cuckoo wanders above its normal breeding- elevation where no Argya or Turdoides breeds it then selects the nests of Garrulax moniliger or G. pectoralis in which to place its egg, and the resemblance between the eggs of fosterer and Cuckoo is then not nearly so complete. Odd eggs have from time to time been found in the nests of queer fosterers such as Bulbuls, Shrikes etc., but these are merely casual instances and do not, I think, mean anything more than that the Cuckoo has not been able to find one of the nests of the proper fosterers.
One hundred eggs average about 23.9 x 18.6 mm., but vary greatly in size.
