Repinned from Dante - Pinned to say that sometimes looking good IS a function in itself. This peacock would be forever alone if he didn't look so vibrant and perfect. -- I agree with what Dante is saying. In the case of the peacock, it could be said that function follows form! It seems as though the form and design of the feathers leads to a useful, secondary function.
Fiery-throated Hummingbird - There are about 338 different species of hummingbirds. There are few other birds that rival the spectacular iridescence of the Fiery-throated Hummingbird. Found only in the cloud forest of Costa Rica and western Panama.
