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. Provided by Wikipedia
