288 LIFE HISTORIES OF NORTH AMERICAN BIRDS. 



He says: " Contopus pertinax is a sparingly distributed summer resident in the 

 pine-forested mountains of south central Mexico, between 8,000 and 12,000 feet 

 altitude. At Los Vigas, Vera Cruz, on June 14, 1893, a nest containing two 

 fresh eggs was found in a pine tree at an altitude of about 8,000 feet. The nest 

 was about 15 feet from the ground, on the outer end of one of the lower 

 branches. It was placed upon a small fork of the main branch. The nest is 

 outwardly composed of grass tops, which are covered with fragments of moss 

 and lichens, and it is lined with the fine heads (seed tops) of a species of grass 

 growing all about under the pine trees of the vicinity. The locality was on 

 a gentle slope at the northeast base of the Cofre de Perote, near Los Vigas, in a 

 thick growth of small pines. The parent birds paid but little attention to the 

 nest, but were cpiite shy, so that some trouble was experienced in obtaining one 

 of them; each time, however, the birds returned to .the vicinity of the 'nest after 

 a long detour through the woods. So far as I saw them, these birds are very 

 quiet during the breeding season." 



The nest, which is now before me, is a compact and neatly built structure, 

 and measures 4| inches in outer diameter by 2 inches in height. . The inner cup 

 is 2£ inches wide by 1\ inches deep. 



Coues's Flycatcher leaves its summer home in southern Arizona and New 

 Mexico about October 1, and apparently none winter within our borders. The 

 eggs are ovate in shape; the shell is frail ancLwithout' luster, of a rich cream tint, 

 and is sparingly spotted, principally about the larger end of the egg, with differ- 

 ent shades of chestnut, ferruginous, and lavender. They resemble very much 

 the eggs of the Olive-sided Flycatcher, but. average a trifle smaller, measuring 

 21.08 by 16.51 and 19.56 by 15.75 millimetres, or 0.83 by 65 and 0.77 by 0.62 

 'inch, respectively. 



The type specimen, No. 26222 (Pi: 2, Fig. 17), United States National 

 Museum collection, the smallest egg of the two, was taken by Mr. Nelson, as 

 already stated, on June 14, 1893, near Los Vigas, Vera Cruz, Mexico.

 Carolina as "Dead-limb bird," extends through the eastern United States north 

 into the southern parts of the Dominion of Canada to about latitude 46° N.,
