A pigeon is a medium-sized seed-eating bird with a small head, short legs and a cooing voice. It's very similar to but generally larger than a dove. There are many varieties of wild or domesticated birds, selectively tamed to carry home messages tied to the neck or leg. A dove is a stocky bird very similar to, but generally smaller than a pigeon. It is gentle and those who oppose violence are referred to as doves.
This trivia may be absolutely useless to you (thank God for small mercies...diary posts cannot be rated) but I felt like posting it. I'm going through an identity crisis :p
