109. in full juvenile plumage. All this species suffer much ab- rasion to plumage and show considerable individual variation as to times of moult and it is possible that juveniles show a similar variation. The species has, I believe, a faculty of moulting when abrasion reaches a certain stage and not at set regular evenly spaced intervals or seasons (apart from the breeding plumage moult) and it is possible if not badly abraded they might miss a moult and moult at different times of the year in different years. This might mean a bird could and might breed in juvenile plumage. Probably some such is the actual condition in rare cases, but the major- ity of birds are nearer normal and do not breed in juvenile plumage.
