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 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 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 manner for some distance, diving suddenly towards the tree on which it intends to alight. All the individuals which I procured were males.
