I visited the Caribbean coast of Mexico last year and saw thousands of grackles. Whilst they're probably the ultimate opportunist in the area with their numbers reflecting it, I like them a lot. They've got character. And iridescent plumage. They've just got funny pyscho eyes. Still, you can't have everything, can you?
They are incredibly varied vocalists, even though the sound may not be pleasing to the human ear, it is the sound most heard in many areas. Thanks for the comment.
