At the age of 58, his fame already assured by publication of his great Birds of America, John James Audubon set out in 1843 on one last expedition to look for new birds. Traveling up the Missouri River with a team of younger naturalists, he did find species new to him, including a few that were new to science. One such novelty was a vireo that he named for expedition member John G. Bell, “an excellent companion in our not unperilous rambles.”
Audubon’s crew first encountered the vireo near what is now St. Joseph, Missouri, and continued to find it as they traveled upriver into the Dakotas. Typically, it was near the river in “the bottom lands, overgrown with low shrubbery, or along the borders of ravines” in prairie country. The species still nests mainly near streamsides or in shrubbery along dense thickets.
