The Philadelphia Vireo is evidently more common in Costa Rica in winter 

 than the Red-eyed Vireo. It has been taken on both the Caribbean and 

 Pacific lowlands and on the central plateau. The birds were fairly numer- 

 ous at El Hogar all through November, 1906, at which time there was 

 a large flight of migrants of various species. While there they were 

 always seen in the trees scattered through the pastures not far from 

 the house and among the fruit-trees in the immediate vicinity of the farm 

 buildings.

 The Red-eyed Vireo is a regular winter visitor to Costa Rica, although 



in small numbers. There are no records of its presence in the lowlands of 



either the Pacific or Caribbean, the lowest point at which it has been 



taken on the eastern side being at Carrillo (about 1,200 or 1,500 feet) and 



on the western side at Boruca (1,500 feet).
