They grow new feathers.
Natural selection is a direct product of the environment. A couple of simple examples are: In a cold environment the only plants and animals that will survive will be cold tolerant plants and animals. In a forest of Bears the only animals to survive will be animals that are faster or bigger than Bears. A sudden change in environmental conditions, such as an Ice Age, will see whole populations of some species disappear while only remnants of some species will survive. Those remnants will display either cold tolerance or the ability to withstand the cold by other means ie: clothing or fire.
animals have fur to keep them warm its the same with feathers and they have fins so they can swim faster
No

rocks weather faster in polluted cities
quetzals adapt to the jungle climate when you change the climate it might die the thin feathers on it's body helps it adapt even better. Jadelike feathers help them fly faster and longer than other birds Camoflage (green-ish feathers) Beak is perfect for the fruit it eats hides in trees from their enemies. When habitat is destroyed, it will inhabit old empty woodpecker holes.
good ski's to ski faster
Quarters and feathers would only fall at the same speed in a vacuum. In air, the quarter would fall faster, as it has less air resistance.
The hollow bones and feathers of birds made them better adapted to their environment than the flying reptiles which became extinct during the Cretaceous Period. Sources: My science book and my own knowledge
It change in faster transportation
things rust faster when in wet areas also the salts acid eats through the metal over an amount of time!
They have:webbed feet so they can swim faster
