The Williamson's Sapsucker was first described in 1852 by John Cassin, an American ornithologist.
Originally, the female was considered to be a different species and named the Black-breasted Woodpecker by Cassin.
The species took its common name from Lieutenant Robert Stockton Williamson, who was the leader of a surveying expedition which collected the first male.
A group of sapsuckers are collectively known as a "slurp" of sapsuckers.
