There can be little doubt that the Swallow of South America is the same as that of 

 the Northern continent, and that it visits the former country during the autuum, 

 winter, and early spring months, retiring northwards in spring to breed. All the 

 records that we can find of the date of the appearance of the bird in South America 

 range between September or October and April, In the West Indies, little is known 

 of E. erythrogaster in Jamaica ; but in Cuba it is found in both autumn and spring 

 migration, appearing the first time in August, and again in May, but it does not 

 spend the intervening months in the island. Dr. Gundlach says that in the autumn 

 birds in perfect plumage are not to be found, but in spring all are in adult feather 21. 

 In Mexico, Grayson says ^^ it is very abundant in May and June at Tepic, where it breeds 

 under the roofs of houses, in the corridors ; he adds ^^ that it is only seen accidentally 

 on the sea-coast in September and October, when it is apparently migrating. It is also 

 said to breed in the Plateau of Mexico i9 ; and we have a note by Mr. le Strange
