Many birds whose summer quarters are in the eastern section of the North-American 

 continent are absent from Western Mexico in winter, are not common even in the 

 Southern States of that country, and only become abundant in Guatemala and the 

 countries lying further south. Thus the well-known eastern bird Vireo flavifrons 

 has only been recorded from the State of Vera Cruz, in Mexico, till we come to the 

 Isthmus of Tehuantepec, where it would appear to be more numerous. In Guatemala 

 it spreads over the whole country, being equally abundant in Costa Eica. In the State 

 of Panama, too, it is frequently found in collections made in that country in the winter 

 months. In Colombia it would appear to be less common, but we have records of it 

 from Minca, near Santa Marta i^, and from P'irico, in the Magdalena valley ^ ; we have 

 also a trade skin from the neighbourhood of Bogota in our collection, the most southern 

 point we know of its occurrence. Dr. Gundlach speaks of having frequently met with 

 V. flavifrons in Cuba ^ ; but he is uncertain whether it is a sedentary species or a 

 migrant. In Guatemala, as already stated, it is common in the winter season. We 

 observed it as early as September 10th, and thence till March. In the environs of 

 Coban it is to be found more abundantly than elsewhere, frequenting the borders of the 

 plantations and the trees of the gardens in the outskirts of the town. 



In the United States it is a very familiar species ; and Brewer gives a full account of 

 its habits ^^. Like other Vireos it builds a pendent nest, which, however, may be 

 distinguished by the profusion of lichens and mosses with which the outer portion is
