268 BIRDS OF WESTERN AXD 



13. Catherpes mexicanus (Sw.). 

 Tejjic, 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 jiart of the coast region." 



14. ThryothoruH fellx Scl. 



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



Mazatlan, Tres Marias, Grayson. 



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

 happy song of the wren is often heard to mingle at all hours of the day. Like nearly aU 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 tlie 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 vjing with the other in their melodious 

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



15. Thryotliorus sinaloa Baird. 

 Mazatlan, Sinaloa, Grayson ; Colima, Xantus. 



" This little wren 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 othcrmse 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. Thryothonis bewickii, 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 iloubtless a constant resident in many localities in the high central plains." 



17. Troglodytes insular Is 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 

 tlie trees or brush covered rocks that crop out every^A'here. 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 Itranch or twig to pour firth its cheerful little song, which is of considerable volume for a bird so 

 small." 



18. Cisiofhorus palustris var. pahidicola Baird. 

 Mazatlan, Grayson. 



Fam. MoTACiLLiD^. 



19. Antlius liidoolcianus (Gin.). 

 Mazatlan, Grayson. 



" Common during; winter months."
