The Snowflake 



In the northern United States and Canada, it is the 

 snowflake or snow bunting, a sparrowy little bird with a 

 great deal of white among its rusty brown feathers and an 

 exaggerated white eyebrow that runs around the cheek

 blasts and snow storms, flocks of these irrepressibly cheer-
