Speke's weaver (Ploceus spekei) was named in honor of John Speke (1827 – 1864), an English explorer and officer in the British Indian Army who made three exploratory expeditions to Africa. He is most associated with the search for the source of the Nile and was the first European to reach Lake Victoria. Speke's weaver inhabits savanna, bush, agricultural land, and towns in northern and eastern Somalia, Ethiopia, Kenya, and northeastern Tanzania.
