Newborn hummingbirds are born the size of a plump raisin. They have no downy feathers, just yellow straw-like strands down the middle of their back. Their eyes are closed and their bodies are black.
After 10 days they develop pin feathers that look like porcupine quills.
Pre-fledglings are fully feathered, have very short tail feathers and a beak less than 1/2 inch long. They are most often found on the ground.
