Of the Bay-breasted Warbler little is known in either Mexico or Central America 

 except in the Colombian State of Panama, where it would appear to be not uncommon 

 during the winter months. In Mexico the sole record of its occurrence is Professor 

 Sumichrast's ^ ; and in Guatemala it is equally rare ; for though we were able to include 

 it in the list of the birds of that country ^, we have never since seen a single specimen 

 from there amongst the thousands of bird-skins we have examined. In Costa Eica it 

 has not yet been detected at all. In its migration to and from its winter quarters, 

 D. castanea, like several of its congeners of the Eastern States, passes the West Indies 

 without stopping, barely touches Mexico or Guatemala, but makes straight for the 

 Isthmus of Panama and the north-western parts of South America. In the latter 

 district it is not uncommon ; and Messrs. Wyatt and Salmon both met with it, the former 

 at Naranjo, in the Magdalena valley, and the latter at Eemedios, in the adjoining Cauca 

 valley. 



For its summer quarters D. castanea makes for Northern New England, and thence 

 spreads to the shores of Hudson's Bay ", in which district it breeds. Southward of this 

 it is known as a bird of passage as far west as the great plains. 



The nest is described by Brewer ^° as large for the size of the bird, and composed 

 outwardly of fine twigs mingled with long hanging mosses; the lining neatly and 

 smoothly made of black fibrous roots, seed-stalks of mosses, and a few hairs. The eggs 

 he describes as bluish green, thickly spotted with brown, and generally with a ring of 

 confluent blotches of brown and lilac round the larger end.
