Here is another example of wildlife that Sir Arthur Conan Doyle was most likely very familiar with, but I was not. I decided it would be nice to add pictures of these birds so you can see them too.
These are mentioned in “The Priory School” in The Greatest Adventures of Sherlock Holmes when Holmes is explaining a map of the moor to Watson. “A few moor farmers have small holdings, where they raise sheep and cattle. Except these, the plover and the curlew are the only inhabitants until you come to Chesterfield high road.”
