Comparison of the Bald, Golden, and Steller’s Sea-eagle

“Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.” (Proverbs 23:5 KJV)

The last post mentioned the Golden Eagle and the Sea Eagle. We were privileged to have seen the Bald Eagle [almost daily here in Polk Country this time of the year.], the Golden Eagle, and the Steller’s Sea Eagle. Just thought you might like a size comparison. The above photo was taken at the National Aviary in Pittsburgh, PA. The two exhibits were side by side and I was overwhelmed at the size of the Steller’s Sea Eagle on the right, and the Bald Eagle on the left. I backed up so I could get them both. What a difference!

The Bald Eagle has a body length of 70–102 cm (28–40 in). Typical wingspan is between 1.8 and 2.3 m (5.9 and 7.5 ft) and mass is normally between 3 and 6.3 kg (6.6 and 13.9 lb).[5] Females are about 25% larger than males, averaging 5.6 kg (12 lb), and against the males’ average weight of 4.1 kg (9.0 lb)

The Golden Eagle is a very large raptor, 66 to 102 centimetres (26 to 40 in) in length. Its wings are broad and the wingspan is 1.8 to 2.34 metres (5 ft 11 in to 7 ft 8 in). Golden eagles’ wingspan is the fifth largest among living eagle species. Females are larger than males, with a bigger difference in larger subspecies. Females of the large Himalayan golden eagles are about 37% heavier than males and have nearly 9% longer wings, whereas in the smaller Japanese golden eagles, females are only 26% heavier with around 6% longer wings.[2][8] In the largest subspecies (A. c. daphanea), males and females weigh typically 4.05 kilograms (8.9 lb) and 6.35 kg (14.0 lb), respectively. In the smallest subspecies, A. c. japonica, males weigh 2.5 kg (5.5 lb) and females 3.25 kg (7.2 lb).[2] In the species overall, males average around 3.6 kg (7.9 lb) and females around 5.1 kg (11 lb). The maximum size of golden eagles debated. Large subspecies are the heaviest representatives of the Aquila genus and this species is on average the seventh-heaviest living eagle species. The golden eagle is the second heaviest breeding eagle in North America, Europe and Africa and the fourth heaviest in Asia. For some time, the largest known mass authenticated for a wild female was the specimen from the A. c. chrysaetos subspecies which weighed around 6.7 kg (15 lb) and spanned 2.55 m (8 ft 4 in) across the wings.[10] American golden eagles are typically somewhat smaller than the large Eurasian species,

Steller’s Sea Eagle is the largest bird in the genus Haliaeetus and is one of the largest raptors overall. Females vary in weight from 6,195 to 9,500 g (13.658 to 20.944 lb), while males being rather lighter with a weight range of 4,900 to 6,800 g (10.8 to 15.0 lb). The average weight is variable, possibly due to seasonal variation in food access or general condition of eagles, but has been reported as high as a mean mass of 7,757 g (17.101 lb) to a median estimate weight of 6,250 g (13.78 lb)… [Above from Wikipedia, with editing.]
