268 BIRDS OP WESTERN AND 



13. Catherpes mexicanus (Sw.). 

 Tepic, Guadalajara, Grayson. 



" Usually met with in the interior, inhabiting the ruins and houses of towns and cities. Not found at Mazat- 

 lan or in any part of the coast region." 



14. Thryothorus felix Scl. 



" " Proc. Bost. Soc. of N. H., xiv, p. 278. 



Mazatlan, Tres Marias, Grayson. 



" The woods of the Tres Marias Islands are well supplied with songsters, in which the ever cheerfiil and 

 happy song of the wren is often heard to mingle at all hours of the day. Like nearly all the birds of these 

 islands, it is very docile, almost suffering itself to be trodden upon, when it is busily occupied in searching 

 among the dry leaves on the ground for its insect prey, indeed most of the specimens procured I killed 

 with a long switch, as I did the Hummers. It seemed to be constantly occupied in searching for insects, 

 occasionally mounting some low branch, often two together, each vying with the other in their melodious 

 rapture, for a few moments at a time, when they would again resume their vocation." 



15. Thryothorus sinaloa Baird. 

 Mazatlan, Sinaloa, Grayson ; Colima, Xantus. 



" This little wi-en is common from Sinoloa to Tehuantepec. Its nest is generally built in the drooping 

 branches of a thorn tree, thus giving the abode of the young some protection against the innumerable ants 

 and other insects that would otherwise infest it. Most of its congeners build their nests in hollow logs, 

 among roots of trees, etc. The nest is partly suspended from the branches and built of fine grass. The 

 eggs are usually five in number, and marked with small specks of a brownish color." 



16. Thryothorus hewickii, var. leucogaster Gould. 

 Guadalajara, Grayson. 



" I found this wren along the stone fences and hedges near Guadalajara, but have not seen it near the 

 Pacific coast. It is doubtless a constant resident in many localities in the high central plains." 



17. Troglodytes insularis Baird. 



" " Proc. Bost. Soc. of N. H., xiv, p. 299. 



Island of Socorro, Grayson. 



" This diminutive species is very abundant and well distributed over the island. As in other members of 

 this family its attire is modest and unpretending, but its song may be heard throughout the day, either among 

 the trees or brush covered rocks that crop out everywhere. I never tired watching them climbing about 

 over old logs, or the trunks of standing trees, creeper like, and often turning up the leaves on the ground at 

 our feet in search of food. In the midst of all this busy occupation for subsistence it frequently stops and 

 mounts a branch or twig to pour forth its cheerftil little song, which is of considerable volume for a bird so 

 small." 



18. Cistothorus palustris var. paludicola Baird. 

 Mazatlan, Grayson. 



Fam. MoTACiLLiD^. 



19. Anthus ludovicianus (Gm.). 

 Mazatlan, Grayson. 



" Common during winter months."
