Sometimes two young Cuckoos are hatched out in the same nest, and then a great struggle takes place between them for possession.
Very odd things occasionally occur in regard to Cuckoo’s eggs. I have found one, perfectly fresh, covered over with moss and down inside a Hedge Sparrow’s nest wherein the bird had laid none of her own. I have known one lie untouched outside a Meadow Pipit’s nest, but whether left there by the layer or cast forth by the owner of the structure it is impossible to say.

WITH FOOD. PHOTOGRAPHED
IN 1/500 OF A SECOND.
A short time ago a friend of mine found a Sedge Warbler’s nest near Gloucester with four eggs in it. The following day when we returned to the place the nest contained only three and a Cuckoo’s egg. As I wanted a photograph of a member of the species for the present work, I parted the thick sedge grass and, erecting my camera within a few feet, got everything ready and went into hiding beneath my apparatus. In less than two minutes she returned and, gazing into her home, suddenly grew greatly agitated and began to hammer the Cuckoo’s egg unmercifully with her bill. Fearing that she might break it before I secured a photograph, I jumped up and drove her away, at the same time calling my companion over to take care of the object of her resentment. Directly it was gone she assumed all her native gentleness of manner and sat down upon her own eggs quite happy.
MORE, PLEASE!
Although young Cuckoos show so much sagacity in getting rid of any other occupants of the nest in which they have been hatched, they sometimes exhibit great stupidity in other directions. For instance, the young bird shown with his Tree Pipit foster-mother in the illustrations figuring in this chapter did not understand the alarm cry of the little brown bird at all. It did not matter however loudly she cried “danger” outside the nest up to a certain stage in his career, if he heard anything moving he shot up his head and opened his mouth very widely in request of food. Then, again, if a newly fledged Cuckoo happens to be resting on level ground and his foster-mother, say a Robin, Hedge Sparrow or Pied Wagtail, comes along with a supply of food, he has not the sense to accommodate himself to the stature of his wee parent, for, instead of lowering his great dappled head, he rears it as high in the air as he can, and the feeder has to stand on his shoulders, as shown in the accompanying photograph, and literally drop the food down his throat.
