New Forrest II.

Birdwatchers near the reclaimed lands of Singapore mistook this kingfisher for a moulting kingfisher, or an albino kingfisher until conservationists theorized that the kingfishers living in the sand dunes had adapted to life in the sand by turning white as camouflage. This phenomenon emerged as a consequence of land reclamation in Singapore during the 70s. Lighter-bodied Kingfishers were able to blend in with the light-coloured sand and were less likely to be eaten by birds of prey in the reclaimed lands. Because the light-coloured Kingfishers were much more effective at hiding from predators, the frequency of the normal morph rapidly dropped to about 0.01%, a phenomenon known as adaptive melanism.
