Notes on the Plumage of North American Birds 



FIFTIETH PAPER 



By FRANK M. CHAPMAN 



(See Frontispiece) 



In its distribution and geographic variations the Horned Lark is among 

 the most interesting of North American birds. The facts that it is the only 

 American member of a family of some 200 species, and that, in spite of its 

 j)lasticity. none of the American races have l)ecome specifically distinct from 

 each other or, as a group, from the Old-World species, leads us to believe that 

 the Horned Lark has reached this country in, geologically speaking, compara- 

 tively recent times.
