Yarrell was born in Duke Street, St James's in London, to Francis Yarrell and his wife Sarah (née Blane). His father and uncle ran a newspaper agency and bookshop. He studied at Dr Nicholson's school in Ealing. His father died in 1794 and the Yarrells moved the short distance to Great Ryder Street, where William lived the rest of his life. In 1802 he became a clerk with the Herries, Farquhar and Co. bank. In 1803 he and his cousin, Edward Jones, joined his father's business. He sometimes left the business in Jones's care, going into the countryside to fish and shoot. He acquired the reputation of being the best shot and the best angler in London, soon becoming an expert naturalist. He sent many bird specimens to Thomas Bewick, who engraved them as woodcuts for his own book of British birds.

His first publication, at the age of 40, was "On the Occurrence of some Rare British Birds" (1825). This was published in the 2nd volume of the 'Zoological Journal' and he later became one of that journal's editors. He was elected a Fellow of the Linnean Society in 1825. He wrote in 1827 on the structure of the tracheae of birds and on plumage changes in pheasants. He corresponded and shared specimens with other naturalists including Thomas Bewick (from 1825), Sir William Jardine, Prideaux John Selby and Nicholas Aylward Vigors, as well as with the Cornish naturalist Jonathan Couch, who provided him with many specimens, especially of fish. Yarrell was one of the original members of the Zoological Society of London. In 1833, he was a founder of what became the Royal Entomological Society of London. He was acknowledged by John James Audubon both as a "valued friend" and for the information and "precious specimens of birds and eggs, collected in the desolate regions of the extreme north." He served for many years as treasurer both of the Entomological Society and of the Linnean Society.

Yarrell's major works were A History of British Fishes (1836) and A History of British Birds (1843), the latter having the same title as the popular book by Thomas Bewick, published from 1797 to 1804, but with a different set of engravings. British Birds was first published "in thirty-seven parts of three sheets each, at intervals of two months; the first Part was issued in July 1837 and the last in May 1843." The sheets were then collected into two volumes, with the addition of "many occurrences of rare birds and of some that were even new to Britain". The additional birds were listed and briefly described in the Preface and "the new subjects have been engraved on single leaves, so paged, that the bookbinder may insert these separate leaves among the birds of the genus to which each respectively belongs." British Birds was illustrated with drawings by Alexander Fussell. Yarrell thanks him for "nearly five hundred of the drawings on wood here employed". The pen for the remaining drawings (the title-page asserts there are 520 in the book) is not stated. Yarrell also thanks John Thompson (1785–1866) and his sons for the "very long series of engravings" of the drawings, as well as his printers, Messrs. Bentley, Wilson and Fley. At the time of its release, Yarrell's Birds was considered the best work on the subject both scientifically and artistically, as noted by Prof. Alfred Newton in his "Prospectus" to the 1871 edition, from which Yarrell's introduction was removed along with the names of contributing artists under Thompson's direction. Both Yarrell's books were so popular that their publisher John van Voorst stated that sales exceeded £4,000. Thomas R. Forbes, in his biographical paper on Yarrell, writes that "All [editions of Birds] are outstanding because of the author's clear, narrative style, accuracy, careful scholarship and unassuming charm." Yarrell's last paper, "On the Influence of the Sexual Organ in Modifying External Character" (1856), described an experiment that disproved the belief that when a stag lacks a healthy testicle, it will fail to grow an antler on that side of the body.
