THE TENNESSEE WARBLER 



Sylvia peregrina, Wils. 



PLATE CLIV. Male. 



So very rare does this little bird seem to be in the United States, that 

 in the course of all my rambles I never saw more than three individuals 

 of the species. The first was procured near Bayou Sara, in the State of 

 Louisiana, in the spring of 1821, when I drew it with the holly twig on 

 which it was standing when I shot it. The second I obtained in Loui- 

 siana also, not many miles from the same spot, in the autumn of 1829, 

 and the last at Key West, in May 1832. Of its migrations or place of 

 breeding I know nothing. 



It is an active and nimble species, an expert catcher of flies, fond of 

 haneins: to the extremities of branches, like several others of the tribe. 

 It utters a single mellow tzveet, as it passes from one branch to another in 

 search of food, or while on the wing, when it moves in a desultory man- 

 ner for some distance, diving suddenly towards the tree on which it in- 

 tends to alight. All the individuals which I procured were males.
