"Oh, what is that bird?" "It is a wheatear. We have seen between two and three hundred since we set out, and I have told you their name twice, nay, three times." --Post Captain, Chapter 10 // The Northern Wheatar, Oenanthe oenanthe, is the species of wheatear found in the UK. Per Wikipedia, "The name "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 most species."
