In the Anastomus oscitans, we have still better evidence that the white plumage is nuptial character, for it is developed only during the summer; the young in their immature state, and the adults in their winter dress, being grey and black. These latter cases offer another instance of the capricious manner in which sexual selection appears often to have acted.
