With more than 10,000 known species of birds in the world, there is a lot of room for diversity among this feathered class. Diet is one of the most obvious points of variation. While some birds sip nectar, others nibble insects; some eat seeds, while others eat fruit.
Then, there are the carnivorous birds. Powerful and cunning, these species capture others from the sky and devour the likes of snakes, lizards, and rodents. Some, like this kingfisher, plunge into the water to catch fish.
