Birds
Birds are said to be descended from dinosaurs. That's an interesting thought!
The study of birds is called Ornithology. What are your favorite birds? In my town, we have blue jays, cardinals, English sparrows, Cedar Waxwings, grackles, crows, peregrine falcons, and even some bald eagles. I am sure there are others, but can't think of them right now, and I'm just trying to fill these pages with some content (smile).
