WORTHEN'S SPARROW 



Little is known of the distribution of Worthen's Sparrow. So far, it has been 

 taken at only three places: Silver City, N. M., June i6, 1884; Chalchicomula, 

 Puebla, April 28, 1893, and Miquihana, Tamaulipas, June 8, 9, 1898. 



TEXAS SPARROW 



The lower part of the Rio Grande Valley is the home of the Texas Sparrow, 

 and it ranges here northwest to Fort Clark, and along the Gulf Coast to Cor- 

 pus Christi, and San Patricio County. It is non-migratory. It also occurs in 

 northeastern Mexico, in the States of San Luis Potosi, Nuevo Leon, and 

 Tamaulipas. 



GREEN-TAILED TOWHEE 



From its winter home in northern Mexico and along the border of the 

 United States, the Green-tailed Towhee moves slowly northward, occupying 

 more than tw^o months — late February to early May — in passing across the 

 less than a thousand miles from the northern limit of the winter home to the 

 northern boundary' of the breeding range. Some dates of spring arrival are: 

 San Antonio, Tex., February 25, 1885; Carlisle, N. M., March 21, 1890; 

 Camp Grant, Ariz., March 6, 1867; Santa Catalina Mountains, Ariz., March 

 18, 1902; near Fort Lewis, Colo., average April 29, earliest April 27, 1906;

 April 25, 1868; Fort Crook, Calif., May i, 1859; Fort Klamath, Ore., May
