DENDECECA. 129 



Like B. coronata, this species visits Mexico and Central America in winter, but, 

 being a western bird, occupies a rather different area during that season. As in similar 

 cases the western form hangs more strictly to the Pacific side of Mexico, and does not 

 migrate nearly so far south as its eastern congener. Not uncommon in collections from 

 Southern Mexico, D. auduboni hardly penetrates beyond that district ; for we only twice 

 met with it in Guatemala : — once in November in company with D. coronata at San 

 Geronimo, 3000 feet above the sea, where both species were feeding on the ground 

 together ; the second time in February, when a solitary bird was shot in an open 

 glade of the pine-forest which clothes the mountains above Totonicapam, 10,000 feet 

 above the sea. Both these birds are in winter dress ; but birds in summer plumage 

 occur in Mexico 3. In the north Audubon's Warbler is well known throughout the 

 Kocky Mountains ; and there seems good reason to believe that it breeds in most of the 

 higher ranges from Arizona to British Columbia. A nest taken in Vancouver's Island 

 by the late Mr. Hepburn is described^ as built outwardly of coarse strips of bark, long 

 leaves of dry grass, and stalks of plants mingled with finer grasses, pieces of cotton 

 cloth and other materials, and inwardly of fine grasses, feathers, lichens, mosses, fine 

 roots, &c. all felted together and lined with fur and feathers. The eggs are pure white, 

 spotted chiefly at the larger end with red markings. 



Dr. Coues's account of this species is very full, both as to synonymy and as to the 

 range and habits of the bird i^.
