Pigargo de Steller (o Pigargo Gigante) en el Puerto de Rausu

Muy buenas,
Hace tiempo que vi un documental donde se mostraban a cámara lenta unas enormes águilas marinas en una bahía japonesa helada mientras una anciana les daba de comer pescado congelado.
Estamos hablando de ésto:
http://es.wikipedia.org/wiki/Haliaeetus_pelagicus 
http://en.wikipedia.org/wiki/Steller%27s_Sea_Eagle
Etymology:
This species was first described as Aquila pelagica by Peter Simon Pallas, in either 1811 or 1826 depending on the source. Subsequently, many generic and specific names have been variously spelled, e.g., Haliaetus pelagicus, Haliaetos pelagica, Faico leucopterus, Faico imperator, Thalassaetus pelagicus, Thalassaetus macrurus, Haliaeetus macrurus and most recently Thallasoaetus pelagicus. Besides its normal common name, the species has sometimes been referred to as the Pacific Eagle or White-shouldered Eagle. In Russian, the eagle has been called morskoi orel (sea eagle), pestryi morskoi orel (mottled sea eagle) or beloplechii orlan (white-shouldered eagle). In Japanese, it is called 0-washi (large eagle or great eagle).

Description:
Steller's Sea-eagle is the biggest bird in the genus Haliaeetus and is one of the largest raptors overall. Females typically weigh from 6.8 to 9 kilograms (15 to 20 lb; 1.07 to 1.4 st), while males are rather lighter with a weight range from 4.9 to 6 kilograms (11 to 13 lb; 0.77 to 0.94 st).[3] At its average weight, the Steller's outweighs both the average Harpy and the average Philippine Eagles by over 0.5 kilograms (1.1 lb; 0.079 st).[3] The Steller's Sea Eagle's length can range from 85 to 105 cm (33 to 41 in). The wingspan is from 1.95 to 2.5 m (6.4 to 8.2 ft) and the wing chord measurement is 57–68 cm (22–27 in).[3][6][5] The Steller's sea eagle has the second largest median wingspan of any eagle.[3] Both the wing chord and wingspan, at an average of 2.13 m (7.0 ft), are similar or slightly smaller than to those of the Steller's close relative, the White-tailed Eagle (Haliaeetus albicilla), which is rather smaller in both weight and total length.[3] As in most Haliaeetus eagles, the tarsus and the tail in this species are relatively short compared to other very large eagles at 9.5–10 cm (3.7–3.9 in) and 32–34.5 cm (13–13.6 in) in length, respectively.[3] The bill is very large. In fact, the skull (at around 14.6 cm (5.7 in)) and the culmen (at around 7 cm (2.8 in)) of the Steller's Sea Eagle are the largest of any eagle and are comparable in size to those of the largest accipitrids, the Old World vultures.

Size relative to a 6-ft (2-m) man:

Vale, aquí se puede ver bien el tamaño de la gran águila de Filipinas (y, sí, es menor a ésta):

Although summer season (June-August) does have more bird species, there are some winter specialties that are well worth seeing in this area of northern Japan. February is probably the best single month for winter birding, the conditions are just right for most of the species to be seen, and towards the end of the winter lasting from December to February the light is strong and bright.  The entire trip went flawlessly: Hokkaido is not heavily populated, the roads are good, and enough English is spoken so that visitors can manage. We visited four main spots, each with their unique features.

Rausu is a small coastal fishing town, population just over 6,200. It’s the most northeasterly town in Japan, and the gateway to the rugged Shiretoko Peninsula. In winter large concentrations of Steller’s Sea Eagles and White-tailed Sea Eagles hunt for fish on the pack ice, which drifts down from the Sea of Okhotsk. Nature tour boats from Rausu harbor are the best way to see these birds. We stayed for three nights in a small minshuku (Japanese style bed & breakfast) famous for nightly visits of the Blakeston’s Fish Owl. The food was out of this world, Hokkaido crabs, sweet and delicious.
Bien, lo que he conseguido reunir:
