VIOLET-GREEN SWALLOW 



Two subspecies of the Violet-green Swallow are in summer confined to 

 western North America. The third {Tachycineta thalassina thalassina) is found 

 only in Mexico. The Northern Violet-green Swallow {Tachycineta thalassina 

 lepida) breeds north to Alaska and Yukon; west to the Pacific Coast; south to 

 northern Lower California and northern Durango, Mex. ; and east to western 

 Nebraska, western South Dakota, and southeastern Alberta. The San Lucas 

 Swallow {Tachycineta thalassina hrachyptera) is resident in the southern half 

 of the peninsula of Lower California, and does not, so far as known, migrate to 

 any extent. All of the following migration data pertain, therefore, to the 

 northernmost form.
