 28th July and 7th January. The moult evidently extends 

 over a considerable period, for birds with moulting heads 

 and half-grown side-plumes were killed in September, 

 October, and November. It would seem that in a wild

 plumages ; middle tail-feathers similarly coloured, but half 

 as long again as the outer pairs, webbed on both sides to the
