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 autumn, 
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 H. erythrogaster in Jamaica; but in Cuba itis 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 2!. 
In Mexico, Grayson says 14, 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; and we have a note by Mr. le Strange
