No, I'm one of those people who is the first to admit when he is wrong. In this case I am not wrong. According to the late Roger Tory Peterson, world renound authority on birds and author of several books on the subject at hand, vultures are not birds of prey.
Webster's told us you were wrong about the correct use of the word "buzzard." It also tells us you are wrong about he correct use of the term "birds of prey."
Websters is simply wrong here. They are including a species of bird that is not a bird of prey into a group that are birds of prey. You sir, are wrong.
Again, from Websters: Main Entry: bird of prey Date: 14th century : a carnivorous bird (as a hawk, falcon, or vulture) that feeds wholly or chiefly on meat taken by hunting or on carrion
Interesting that you included the part about carrion in your second post, but not your first. I suggest that you review Field Guide to North American Birds published by National Geographic, or the National Audubon Society's Field Guide to North American Birds or Roger Tory Peterson's Peterson's Field Guide to Birds of Eastern Norht America. These books are considered by most to be the most informative on the subject. I seriously doubt anyone in the birding world would recognize or even consider Webster's Dictionary as a plausable replacement.
Once you have read up on the subject, then go fly with them for 28 years as I have. Observe them. Watch their behavior. Learn to identify each and every species of soaring bird at a casual glance, then come back and we'll talk birds. You'd better get busy, you've got a lot to learn.
