Falco peregrinus
Tunstall was born at Burton Constable in Yorkshire. In 1760 he succeeded to the family estates of Scargill, Hutton, Long Villers and Wycliffe. Being a Catholic, he was educated at Douai in France. On completing his studies he took up residence in Welbeck Street, London, where he formed an extensive museum, as well as a large collection of living birds and animals. He is known for formally describing the Peregrine falcon. After his marriage in 1776 the museum was moved to Wycliffe, and at the time was one of the finest in England.
