These tiny seabirds use camouflage when it comes to breeding time.  Seen here in their tawny breeding season colours that blend in with their preferred nesting location.  These birds are becoming endangered, primarily because their nesting habitat is dwindling rapidly – they depend on old growth forest in which to build their nests and have been known to fly several kilometres inland in order to find the right nest site.  After the breeding season they return to their more common dark grey/black and white non-breeding or winter colouring, which is in common with their close cousin, the ancient murrelet.  These are a timid bird and when you see them on the coast you have to use some stealth tactics of your own to get a little closer – once they see you they will turn their backs and swim away.
