 to the White Mountains and Nova Scotia; winters in the tropics.

 doubtless show it is more common than is generally supposed.

 The Robin is our most abundant summer resident, and in favorable 

 localities a few may be found in the winter. Migrants begin to 

 arrive toward the last of February and the species is abundant 

 until December. (See Group, Gallery, between Cases A and B.)
