121. Toxostoma lecontei lecontei. Leconte's Thrasher. — 



Seen several times in the sandy stretches of the lower 

 western slopes of the Pattie Basin. They were shy 

 and difficult to approach, but on April 7 I pursued 

 one through the creosote bushes on horseback, and 

 shot it from the saddle when it took flight. It proved 

 to be a male. 



122. Toxostoma crissale. Crissal Thrasher. — Two speci- 



mens were taken in the Cocopahs by Rhoads, who 

 saw not more than five altogether. 



123. Heleodytes brunneicapillus couesi. Cactus Wren. — 



Resident throughout practically all the region visited, 

 particularly in the washes west of Pattie Basin. An 

 occupied nest of the species was seen in a cholla 

 cactus and another in a palo verde. A noisy pair of 

 the birds was usually in evidence in the oasis around 

 the Tres Pozos. A bob-tailed fledgling was collected 

 on April 5 in the Pattie Basin, and a fully-grown young 

 bird (male ?) in the desert south of Mexicali on 

 April 19. 



Rhoads collected the species in February. 



124. Salpinctes obsoletus obsoletus. Rock Wren. — Six 



specimens were taken in the Cocopahs by Rhoads, 

 who, judging from his note on the species, was very 

 deeply impressed by the personality of this bird. 



125. Troglodytes aedon parkmani. Western House Wren. 



— Two or three were seen by Rhoads, and one col- 

 lected. 



126. Nannus hiemalis pacificus? Western Winter Wren. 



— ''Two or three wrens seen in woods near Colony 

 were presumably this form" (Rhoads). 



127. Telmatodytes palustris paludicola. Tule Wren. — Two 



obtained by Rhoads at the mouth of the Hardy. 



128. Telmatodytes palustris plesius. Western Marsh 



Wren. — One specimen collected with examples of the 

 preceding race by Rhoads. 



129. Auriparus flaviceps flaviceps. Verdin. — Widely dis- 



tributed throughout the whole region. Rhoads caught 

 one *'in its gourd-like roosting nest'' in February.
