Blue-breasted kingfishers may look bright blue, but they are actually a murky brown colour. This is due to the difference between pigmented and structural colouration. If we were to just see the light reflected directly from the wings it would be brown, but small air bubbles interfere with the light in just the right way to reflect only blue light.
Blue-breasted kingfishers eat Insects, arthropods, fish, frogs, and occasional fruit from oil palms.
They fly so quickly that they can penetrate a layer of ice to catch a fish.
