My mom just sent me this link that is filled with amazing pictures of baby hummingbirds. Someone found a hummingbird nest and carefully took pictures starting with the eggs all the way to the young bird leaving the nest. It took just 24 days from birth to flight.
There are five pages in all, with the last picture showing a matchstick and a penny in the nest so that you can visualize the actual size. Amazing!
