Similar in large size and whiteness of under parts * to D. p. nelsoni, 

 but with less of white on wing-coverts, sometimes with none, the 

 spots, when present, only on terminal or (usually) subterminal por- 

 tion, and on only a few of the covert feathers. 



o Many winter specimens from eastern Massachusetts, etc., are precisely like 

 typical D. p. nelsoni in coloration and very nearly as large, and probably should be 

 referred to that subspecies. Certainly they are much nearer D. p. nelsoni than to 

 D. p. medianus from Pennsylvania, etc. 



6 Also in tendency to reduction or absence of bars on lateral rectrices.
