It's a little outdated (apparently maniraptors are a kind of fish O.o ), but that is indeed one of my favorite shorts. In fact, I've got a soft spot for all the "edutainent" shorts Disney made back then ("Toot, Whistle, Plunk, Boom" ect.)
Wow, poor bird. I wish for the life of me I could remember if I've ever seen said cartoon. Your pic screams to me that I have but I really can't remember it. They should put it back on youtube so I can check it out.
