In the case of this particular creature, this characteristic manifests itself in the fact that some females attain a slightly larger average weight. The species as a whole develops respectable measurements. Adults reach an average body length of about 20 – 24 in (50 – 60 cm).

A typical wingspan for both genders, furthermore, equates to roughly 46 in (117 cm). Weight, though, remains where the genders differ slightly, overall averages remain approximately equal. To be precise, a typical weight equals roughly 1.88 lb (0.85 kg).

In terms of appearance, however, no gender-based differences appear. In point of fact, both sexes of the remarkable Black-and-white hawk-eagle remain virtually indistinguishable. As the common name suggests, the basic color scheme appears as black and white.

Impressively, that native territory does not simply entail minor regions of the two continents. More precisely, the fascinating bird appears as far north as southern Mexico. However, its known endemic range also extends as far south as the country of Argentina.

Within this wide range, though, it possesses highly specific requirements. That holds true since it only inhabits specific habitat types. These consist of lowland forests of any type. While it does inhabit highly humid and dense forests if it must, these are not preferred.

The physically impressive bird has even more decidedly precise preferences for where it makes its home. It only inhabits such regions that appear at lower altitudes, unless forced to relocate there. This marvel of Nature also prefers regions with close-packed canopies.

Like other raptors, the stunning Black-and-white hawk-eagle evolved to feed exclusively as a carnivore. Although it hunts opportunistically, it does, like most animals, have preferred prey. These primarily consist of various toads, small mammals, and lizards.

One more unusual factor about its nature remains, though. To the surprise of many researchers, a large percentage of its diet also consists of various types of small birds. Although certain animals prey on its young in the nest, adults have few natural predators.
