GREAT-CRESTED GREBE. 



303 



Adult females do not differ much from old males, except 

 that they are not quite so large in size ; the crest is also a 

 little smaller, and the general colours of the whole plumage 

 less pure. 



Young birds in their first winter, and during part of their 

 second year, have but small crests, and little or no reddish- 

 chestnut colour. For some time after they are hatched the 

 young chicks have their bills mottled black and white : the 

 head and neck ornamented with long dark stripes on a ground 

 colour of dull greyish-white ; the upper surface of the body 

 dark brown, with longitudinal stripes of light brown , the 

 whole under surface white. The young bird figured below 

 was obtained in Norfolk.
