BRITISH BIRDS. 



The young differ still more in appearance from their parents — so much 

 so that they have been erroneously described as a distinct species under 

 the name of Turdus solitarvus. They have the general colour greyish 

 brown^ much paler on the margins of the feathers of the throat and belly ; 

 the quill- and tail-feathers have light brown margins. This brown plumage 

 is changed during the first autumn for the showy dress of the parents ; 

 and in the moult, when the feathers are in process of being changed, 

 these young birds present a very singular piebald appearance.
