Well, if the habitat is different colors that would affect a species fur color for say. The slightest difference in a habitat would make a big difference in how something evolves. If one honeycreeper lived in a slightly colder habitat they would evolve to grow more feathers than a honeycreeper that lived in a warmer habitat. Same goes for color, if a honeycreeper lived in a more dull colored habitat their feathers would be more stale and dull colored rather than one who lives in a more vibrant and colorful habitat. This is so they naturally camouflage better with their environment.
it might affect the evolution because each bird might have its own needs therefore it evolves different from other birds. ex: one bird might eat insects out of a tree so to make that job easier it must evolve and become a bird with a longer beak to reach the insect easier. hope this helps :D
