Claim: The etymology of Desert wheatear came from the Latin word "deserti," which means "dessert" and "wheat," referring to the prominent wheat found in some of its species.
Evidence: "Wheatear" is not derived from "wheat" or any sense of "ear", but is a 16th-century linguistic corruption of "white" and "arse", referring to the prominent white rump found in many species. 
The specific deserti is Latin for "desert".
