In 1827 the American ornithologist John James Audubon included an illustration of Bewick's wren under the binomial name Troglodytes bewickii in his The Birds of America. In the companion Ornithological Biography, published four years later, Audubon explained that he had shot the specimen near St. Francisville, Louisiana in 1821 and had chosen the specific epithet bewickii in honour of his friend the engraver Thomas Bewick. Bewick's wren is now the only species placed in the genus Thryomanes that was introduced by the English zoologist Philip Sclater in 1862. Wikipedia
