THETOPHILTJS. 83 



In Guatemala this Wren is a common bird, as we found it abundant at all seasons in 

 the neighbourhood of Duenas and even as high as Calderas in the Volcan de Fuego, at 

 an altitude of over 7000 feet. It is also found equally abundant in the low-lying 

 country bordering the Pacific, in the neighbourhood of towns and villages, at as low an 

 elevation as 1000 feet above the sea. Specimens obtained on the line of the Panama 

 Railway were found at a much lower elevation than this. 



Its place of resort is usually moderately thick forest, choosing trees of dense matted 

 growth rather than thickly grown underwood. Its song is powerful and melodious, 

 but with no great variation.

This species may be considered to represent Thryophilus rufalhus in Mexico, where, 

 however, it has a limited range, which does not appear to pass beyond the western 

 coast of that country. Here its presence was detected by the two naturalists Grayson 

 and Xantus, to whose exertions our knowledge of the ornithology of Western Mexico 

 is almost entirely due. The following short note by the former traveller is the only 

 account we have of the bird : — "This little Wren is common from Sinaloa to Tehuan- 

 tepec. Its nest is usually 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, &c. 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 colour."
