110 TENNESSEE SWAMP WARBLER
|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 Louisiana 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 hanging to the extremities of branches, like several others of the tribe. It utters a single mellow tweet, as it passes from one branch to another in search of food, or while on the wing, when it moves in a desultory manner for some distance, diving suddenly towards the tree on which it intends to alight. All the individuals which I procured were males.
