“I shot the two little birds here represented, near the village of Henderson, in the State of Kentucky, in May 1811.  They were both busily engaged in searching for insects along the branches and amongst the leaves of a Dog-wood tree.  Their motions were those common to all the species of the genus Sylvia. On examination, they were found to be both males.  I am of opinion, that they were both young birds of the preceding year, and not in full plumage, as they had no part of their dress seemingly complete, excepting the head.  Not having met with any other individuals of the species, I am at this moment unable to say anything more about them.  They were drawn, like all the other birds which I have represented, immediately after being killed; but the branch on which you see them was not added until the following summer.

The common name of this plant is Service Tree.  It seldom attains a greater height than thirty or forty feet, and is usually found in hilly ground of secondary quality.  The berries are agreeable to the taste, and are sought after by many species of birds, amongst which the Red-headed Woodpecker is very conspicuous.”
