 mcsi^^m [0. S. & F. B. G.^). 



The first published account of this pretty species is that by J. P, Giraud, who gave a 

 figure of it in his 'Descriptions of Sixteen New Species of North- American Birds 

 collected m Texas'^; but it was probably discovered some ten years previously by 

 Deppe in Southern Mexico, as the specimens named by Lichtenstein Parus erythropis 

 in the Berlin Museum ^^ were obtained, as were so many other Mexican birds, 

 by that energetic collector. Another name, Cardellina amicta, was subsequently 

 bestowed upon it by the late Vicomte DuBus, who figured it in his ' Esquisses Orni- 

 thologiques ' ^ ; and a description of it under this title was given by Bonaparte in his 

 ' Conspectus ' ^°. All these names are now acknowledged to belong to C. rubrifrons. 



Giraud, as already stated, inserts C. rubrifrons as a bird of Texas ; but whether it 

 really occurs in this border State is very questionable. In Southern Arizona, however, 

 the fact of its presence has been established by Mr. W. H. Henshaw, who found it in 

 several places in July 1874, when young birds were also observed. Southward of this point 

 we have no record of its occurrence until we reach Southern Mexico, where it has been 

 observed in the higher districts by several ornithologists. In Guatemala it is restricted 

 to the higher regions of the main cordillera and the forests of the volcanos. We never 

 observed it ourselves below an elevation of 7000 feet in the forest-belt of the Volcan de 

 Fuego, where it was common, and in the mountains above Totonicapam, at an elevation 

 of about 10,000 feet. In the former district we found it in damp forests of mixed trees, 

 and in the latter in pine-forests, its resort in Arizona, according to Mr. Henshaw. 



In its habits it somewhat resembles the restless Paridse ; but it takes insects on the 

 wing and jerks its tail like a Setophaga. 



In Southern Mexico and Guatemala C. rubrifrons is probably resident throughout 

 the year, though we observed it only during the dry winter months, the places frequented 

 by it during the rainy season being not easily accessible. In Arizona it may be migra- 

 tory ; but on this point our information is incomplete. 



The young have been described by Mr. Henshaw7; but its nest and eggs have not yet 

 been met with.
