SAN LUCAS THRASHER 377 



Mr. Sennett (1879) says that "it feeds upon the como and other 

 berries, as well as insects and larvae." 



The behavior, voice, and other habits of Sennett's thrasher seem 

 to be similar to those of the brown thrasher, to which it is so closely 

 related. According to Dr. Friedmann (1929), it has occasionally 

 been imposed upon by both the dwarf cowbird and the red-eyed 

 cowbird.

 (Mexico City) ; Hidalgo (Jacala) ; Queretaro (Jalpan) ; San Luis 

 Potosi (Angostura) ; Coahuila (Sabinas) ; and Texas (Del Rio). 



The typical subspecies, the long-billed thrasher {T. I. longirostre) ^ 

 is found only in Mexico from Queretaro and Veracruz southward, 

 Sennett's thrasher {T. I. sennetti), the race occurring in the United 

 States, is found from Texas to San Luis Potosi and Tamaulipas. 



Casual record. — A specimen was collected at Barr, Colo., in May 

 1906. 



Egg dates. — ^Texas: 135 records, April 2 to June 24; 82 records, 

 May 6 to 23, indicating the height of the season.

TOXOSTOMA CINEREUM CINEREUM (Xantus) 



SAN LUCAS THRASHER 



HABITS 



John Xantus (1859) described and named this species, which he 

 says is "very similar to Mimus montanus [sage thrasher], with longer 

 and more curved bill. The upper parts are grayish brown or cinere- 

 ous with a faint trace of rufous on the rump. Beneath white with 

 a tinge of brownish yellowish towards the vent ; the breast and sides 

 with sharply defined sagittate or subtriangular spots of brown, 

 scarcely elongated on the sides, the shade of brown similar to, but 

 darker than that of the back. The lateral tail feathers are tipped 

 with white, the outer one sometimes edged with the same. There 

 are two narrow dull whitish bands on the wings." 



This, the type race of the species, occupies about the southern half 

 of the peninsula of Baja California, ranging north to about latitude 

 28°. Another race, Tnearnsi, is found farther north on the penin- 

 sula, and there is another race in southern Mexico.
