Young birds have transverse blackisli bars on tlie back, and bhickisli 

 spots beneath. The shafts of thi' lesser coverts are streaked with l>rownish- 

 vellow ; the back leathers with white. 



There are some variations, both 

 of color and proportions, l)etween 

 eastern and western specimens of 

 the Jiobin. In the latter there is 

 a tendencv to a lonjjjer tail, though 

 the difference is not marked ; and, 

 as a rule, they slightly exceed east- 

 ern specimens in size. The broad 

 white tip to the later,al tail-feather 

 — so conspicuous a mark of east- 

 ern birds — is scarcely to be fcmnd 

 at all in any western ones ; and in 

 the latter the black of the head 

 is v(>rv sharply defined against the 



lighter, clearer ash of the back, there hardly ever l>eing a tendency in it 

 to continue backward in the form of centrjd spots to the feathers, as is 

 almost constantly seen in eastern examples ; of western specimens, the 

 rufous, too, is appreciably lighter than in eastern. As regards the streaks 

 on the throat, the black or the white may either largely predominate in 

 specimens from one locality. 



Turdus misratorius.
