Palm-nut Vulture vs Spanish Imperial Eagle

Palm-nut Vulture (Gypohierax angolensis)

Palm-nut Vulture

Gypohierax angolensis

Huge1.6 kgForest

This is a nearly unmistakable bird as an adult. At 1.3–1.7 kg (2.9–3.7 lb) in weight, 60 cm (2.0 ft) in length and with a wingspan of 1.50 m (4.9 ft), this is the smallest Old World vulture. Its plumage is all white except for black areas in its wings and tail. It has a red patch around each eye. The juvenile, which takes 3–4 years to mature, is brown with yellow eye-patches. In flight, this species resembles an eagle more than a typical vulture, and it can sustain flapping flight, so it does not depend on thermals.

Spanish Imperial Eagle (Aquila adalberti)

Spanish Imperial Eagle

Aquila adalberti

Huge3.0 kgWoodland

This is a large raptor and quite large eagle, broadly similar in size to its cousin, the eastern imperial eagle, which is found in a considerably different distributional range. Compared to sympatric largish booted eagles, it is somewhat smaller than the golden eagle and somewhat larger than Bonelli's eagle. Spanish imperial eagles can weigh from 2.5 to 4.8 kg (5.5 to 10.6 lb). The average weight of males in a sample of 10 was 3.19 kg (7.0 lb) while that of 17 females was found to be 3.43 kg (7.6 lb). Meanwhile, another sample of 10 unsexed adults weighed an average of 3.93 kg (8.7 lb).
