This was not an albino kiwi (a condition of no pigmentation) but a North Island Brown Kiwi with white feathers. Since then, two more white kiwi have also hatched.

Feathered dinosaur
Although growing evidence of the relationship of non-avian dinosaurs to birds raised the possibility of feathered dinosaurs over the twentieth century, it was not until the mid-1990s that non-avian dinosaur fossils were discovered with clearly preserved feathers. Since then, feathers or feather-like integument have been discovered on dozens of genera of dinosaurs via both direct and indirect fossil evidence.Although the vast majority of feather discoveries have been for coeleurosaurian theropods, the discoveries of integument on at least three ornithschians raise the likelihood that proto-feathers were present in basal dinosaurs, and perhaps even a more ancestral animal, in light of the pycnofibers of pterosaurs.All modern birds possess feathers, with the exception of a few artificially created chickens.
