BRONZED COWBIRD 



The Bronzed Cowbird {Tangavius aneus) is a tropical bird of Central 

 America and Mexico, of which there are now recognized three subspecies. One 

 of these, the Lesser Bronzed Cowbird {Tangavius cBueus assimilis), is found 

 only in southwestern Mexico from Oaxaca to Jahsco. Both the others occur in 

 the United States, but only along the southwestern border. The distribution 

 of these is as follows: 



The Bronzed Cowbird (Tangavius cBneus cenciis) ranges in northwestern 

 Mexico south to Tepic and north to Sonora. It has been taken also in Arizona, 

 at Tucson on April ir and May 21, 1909, and at Sacaton on May 28. 



The Red-Eyed Cowbird (Tangavius ceneus involucratus) occurs north to 

 central southern Texas and south through eastern Mexico and Central America 

 to Panama. It is resident in the valley of the Lower Rio Grande, but is appar- 

 ently only a summer visitor farther north in Texas.
