 practically the same as of the preceding bird. 

 The two species associate in flocks during the 

 winter and can only be distinguished by close 

 attention to their head markings and songs.

 hills, becoming rare in the extreme southern 

 part of the State.

 variety. Length five inches or more. Fore-
