What are the uses of outer covering of birds?

Answer 1

The feathers, or plumage, of a bird have the following purposes:

• In many bird species, the male's brighter colouring or markings help attract a female
• Waterproofing - most birds have feathers that help to waterproof them against rain or the water of the habitat in which they live
• Camouflage - many birds have plumage that enables them to blend in with their surroundings
• Insulation - some species of birds, which live in colder climates, have feathers which are arranged and structured so as to insulate them better against the cold

Answer 2

The outer covering of birds, specifically feathers, serves various purposes such as providing insulation to regulate body temperature, aiding in flight by reducing air resistance, displaying for courtship and camouflage for protection. Feathers also play a role in waterproofing, helping birds stay dry in wet conditions.
