 natis ; fronte et capitis lateribus Isete flavis ; alis et cauda nigris, extus cinereo limbatis, illis albo bifasciatis, 

 hnjus rectricibus tribus utrinque extemis albo pro majore parte notatis ; snbtus gula nigra, corporis reHquo 

 cum hypochondriis pure albis ; rostro et pedibus nigricantibus. Long, tota 4'9, alse 2-7, caudae 2-2, rostri

 mala. Mus. nostr.) 



Hob. North America, Rocky Mountains to Pacific Ocean from the Columbia river 

 southwards ^ ^. — Mexico, Moyoapam (Sumichrast ^), La Parada {Boucard ^); Guate- 

 mala, Volcan de Fuego, San Geronimo, Alotepeque {0. S. & F. B. G. ^ ^). 



So little was known of this species in 1862 and 1863 that specimens that then came 

 into our possession were in one case referred to a different species ^ and in another 

 described as new ®, errors which were soon afterwards corrected ^, and Mexican and 

 Guatemalan examples referred to the bird discovered by Nuttall and Townsend on the 

 banks of the Columbia river in 1835. Since then D. occidentalis has been found in many 

 parts of the Rocky Mountains and in Arizona^. In Mexico its range seems quite 

 confined to the higher districts, Professor Sumichrast having obtained it at an eleva- 

 tion of 8200 feet above the sea. In Guatemala, though it was perhaps most abundant 

 in the belt of pine trees of the Volcan de Fuego which covers the mountain above 

 10,000 feet, we nevertheless found it at much lower elevations, having shot specimens 

 in the hills surrounding the plain of Salaraa about 3500 feet above the sea, and near 

 the mines of Alotepeque at a similar elevation. The bird is always found in the pine- 

 forests ; but the trees being of moderate height, specimens were not difiicult to obtain. 

 Its habits are similar to those of B. virens ; and throughout the day it searches restlessly 

 for food in the outer branches of the trees. 



Of its breeding nothing has as yet been recorded. In Guatemala and Mexico it is 

 doubtless only a winter visitant ; and in the southern part of its range in North America 

 it has only been observed on passage ; but, as Dr. Cones remarks ^ it may yet be found 

 to build in the higher pine-belts of the Colorado watershed. The northern part of 

 its range is its summer quarters ; and here it no doubt breeds.
