Educated at Ampleforth College, he served for several years in the militia, joining the 3rd battalion of the York and Lancaster Regiment in 1839 and retiring with the rank of captain in 1864.
[1] In 1857 Salvin inherited from his uncle, Thomas Monnington Webbe-Weston, the Tudor mansion Sutton Place, Surrey, but usually lived at Whitmoor House on the estate.
[2][3] He trained young otters to follow him like dogs and sleep in his lap, and at one time kept a wild boar with collar and bell.
[1] Salvin's early love of hawking was stimulated by an acquaintance with John Tong, assistant falconer to Thomas Thornton.
In 1864, Salvin took three birds, Izaak Walton, Hobble Gobble, and Detective, to Corby Castle to demonstrate cormorant fishing.
Rosalie Hook described the bird as a "tolerably patient sitter but a troublesome guest as he insisted on fish diet without a particle of salt on it & I had to drive to Farnham for his dinner".
Salvin also assisted Gage Earle Freeman with Falconry: its Claims, History, and Practice (1859), the Remarks on training the Otter and Cormorant appended to it being his.
