William Yarrell

William Yarrell (3 June 1784 – 1 September 1856) was an English zoologist, prolific writer, bookseller and naturalist admired by his contemporaries for his precise scientific work.
Yarrell is best known as the author of A History of British Fishes (2 vols., 1836) and A History of British Birds featuring 564 original engravings (in 3 vols., first ed. 1843, second ed. 1845, third ed. 1856). The latter went into several editions and was the standard reference work for a generation of British ornithologists. He described Bewick’s swan in 1830, distinguishing it from the larger whooper swan.
