The survival rate of raptorial birds tends to increase with larger body size, with a 30–50% annual loss of population rate in small falcons/accipiters, a 15–25% loss of population rate in medium-sized hawks (e.g., Buteos or kites) and a 5% or less rate of loss in eagles and vultures. The oldest known wild golden eagle was a bird banded in ...
322 non-carrion prey items were found for greater spotted eagles in the Belaya River, 59% of which were mammals. The diet was largely European water vole at 32.6%, followed by smaller voles and mice. It was found that the Belaya eagles ate a large balances of reptile prey (19.5%)—in fact, 15% of all vertebrate prey were European adders. The ...

[8] While found across a wide range, today breeding from as far west as Greenland and Iceland across to as far east as Hokkaido, Japan, they are often scarce and spottily distributed as a nesting species, mainly due to ...
The maximum cited weight for steppe eagle males in the wild is 4.6 kg (10 lb) while that for females is 5.5 kg (12 lb). [43] Among standard measurements, the wing chord can measure from 510 to 610 mm (20 to 24 in) in males and from 536 to 640 mm (21.1 to 25.2 in) in females.

The martial eagle can be found in most of sub-Saharan Africa, wherever food is abundant and the environment favourable.With a total estimated distribution of about 26,000 km 2 (10,000 sq mi), it has a substantial distribution across Africa, giving it a somewhat broader range than other species there like the crowned eagle (Stephanoaetus coronatus) and the Verreaux's eagle (Aquila verreauxii).
