What type of body covering does a hummingbird have?

Hummingbirds are covered in iridescent feathers that can display a range of vibrant colors, thanks to microscopic structures that refract light. These feathers are lightweight and specialized for flight, allowing for their exceptional agility and maneuverability. Additionally, hummingbirds have a layer of down feathers underneath to provide insulation. Their unique plumage not only aids in flight but also plays a role in attracting mates.
