med externally of hemp, flax, or woolly substances, and is well lined with different kinds of hair, intermixed with softer materials. It breeds twice during the summer, and returns southward in the beginning of autumn, in small parties, shifting chiefly by night. During the breeding-season, this little bird, when approached, shews great anxiety for the preservation of its eggs or young, and tries, with all the artifices employed by many other species, to entice the aggressor away from its nest. They are seen, on their return to the south, passing through Louisiana in October.
I made my drawing of this species near Natchez, and having killed the specimen while it was searching for insects among the flowers of a large climbing plant, I have figured part of the latter also. This plant I have never seen, excepting in low, damp or marshy places. It there runs over decayed trees, spreading in the form of a bower, and hanging in graceful festoons. The long pendulous clusters of pale purple flowers are destitute of odour.
