Finches are small, seed-eating songbirds. They come in a huge variety of colours and patterns, and can be found all over the world. Many finches are very pretty and make good pets.
A flamingo is a pink wading bird. They eat shrimp that is in the water by filtering it through their beak. Their pink colouring comes from the food they eat.
A fledgeling (also spelt fledgling) bird is one that has just grown its adult feathers and is ready to learn to fly. Someone who is just starting out doing something can also be called a fledgeling, or a novice.
