It is not possible to draw a sharp line between plumages I and II or between II 

 and III, many specimens being intermediate, and these have had to be arbitrarily 

 placed. In the former instance all specimens having white predominating in the 

 tail-bands have been referred to group I, while in the latter all those showing little 

 contrast in color between the back and the tail have been referred to group III. 

 Quite evidently the relative proportion of the rufescent to the other plumage must 

 vary according to the particular series obtained in any one coimtry, though it seems 

 significant that all of the considerable number of Texas examples represent one style 

 of plumage only.
