18 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 solitarius. 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 ight 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.
