Audubon in Louisiana
Yellow-throated Vireo, or Greenlet

Yellow-throated Vireo, or Greenlet
Vireo flavifrons, Vieillot
Octavo edition, plate 238
“While the small White-eyed Vireo rambles among the low bushes and brambles of the fields of all parts of the United States, the Yellow-throated species takes possession of the forest, and gleans with equal ease among the branches of the tallest trees, to which it seems to give a marked preference during the spring and summer. It is fond of the quietest solitudes . . . This species is at all times extremely rare in Louisiana, where I have seen it only during early spring or late in the autumn. . . .”
