As the cuckoo chooses the nest some days beforehand, it may be thought, if the nest is an open one, that the cuckoo looks upon the colour of the eggs within it while her own is in process of maturing inside her, and that it is thus her egg comes to assume the colour of the others; but this explanation will not hold good for nests that are made in the holes of trees, as that of sylvia phaenicurus, or which are oven- shaped with a narrow entrance, as with sylvia rufa.
