" The Purple Martin is the only Swallow with which I am acquainted that will 

 readily perch on trees which are covered with foliage, alighting amid the leaves after the 

 manner of nearly all the Passerine birds, but they never hop from twig to twig. The 

 song of the Martin is loud and cheerful ; in autumn, when they are more generally dis- 

 tributed than at other times, these clear notes frequently reach the ear when the birds 

 are almost invisible, as they sail high in the air with a strong and graceful flight. Early 

 in September these birds migrate south, but do not remain in Florida all winter, and 

 not one is to be seen in the State after the 1st of November." 



The figures in the Plate have been drawn from specimens in the Salvin-Godman 

 collection, and the descriptions are taken from examples in the British Museum.
