Take a tip on White-bellied Sea-Eagles

Here's a tip on White-bellied Sea-Eagles. They've got two-tone tongues. Standard pink, with grey-brown flexible tips. Looking like claws, as in above image, but actually front section of tongue tightly folded lengthwise (an ability that genetically divides people: many can, many can't).

Another tip: the birds can be remarkably tolerant of a patient open approach. Bit of chat doesn't worry them either. Don't expect much by way of reply. 

And it can be frustrating trying to gain their full attention. They seldom deign to look straight at the camera, no matter how much direction is being given from behind the camera.
