The most striking characteristic of the Gray-cheeked Thrush is its 

 rapid migration, probably the most rapid of all North American birds. 

 Scarcely five weeks are occupied in the journey from the Gulf of Mexico to 

 Alaska, an average speed of a hundred miles a day and a probable speed 

 during the latter part of the journey at least twice as great.
