I didn't realize that so many names can be used for one species, but it does make sense when I think about it. It would be great if, at least once, a common named was used in the post for those of us not fluent in proper scientific names. I am getting better at recognizing certain ones-like Tom-but every once in a while I get thrown for a loop. Not that I don't mind the challenge, but when there so many interesting posts to read it can get frustrating! Thanks for explaining it, though, Kurt.
