Nice! Although this impressive species is kept in many zoos, it is still worth taking a closer look at the ones in the Tierpark: Among their normal Steller's sea eagle like the bird on this photo, the dark 'niger' morph bird is still on display too. This is the only known living 'niger' morph and the specimen that finally proved that it is a morph instead of separate race/species.
I didn't knew that. Thanks for the info! Honestly, I have a passion for get as many species photographed as I can, but I don't care too much on morphs, varieties, breeds or even subspecies.
