Hooded crow in the context of "Omnivorous"

An omnivore (/ˈɒmnɪvɔːr/) is an animal that eats both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet.

Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears.

The American crow (Corvus brachyrhynchos) is a large passerine bird species of the family Corvidae. They are a common bird found throughout much of North America, only absent from the tundra biome. American crows are the New World counterpart to the carrion crow and the hooded crow of Eurasia, occupying similar ecological niches.

American crows have all-black plumage, with iridescent feathers. They look similar to other all-black corvids. They are highly intelligent, similar to other Corvidae, and are adaptable to human environments.

The carrion crow (Corvus corone) is a passerine bird of the family Corvidae, native to western Europe and the eastern Palearctic. Along with the hooded crow (Corvus cornix), the carrion crow occupies a similar ecological niche in Eurasia to the American crow (Corvus brachyrhynchos) in North America. The two species look very similar to one another, but can be differentiated by size, as the carrion crow is larger and of a stockier build compared to the American crow.

Corvus is a widely distributed genus of passerine birds ranging from medium-sized to large-sized in the family Corvidae. It includes species commonly known as crows, ravens, and rooks. The species commonly encountered in Europe are the carrion crow, hooded crow, common raven, and rook; those discovered later were named "crow" or "raven" chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for "raven".

The 46 or so members of this genus occur on all temperate continents except South America, and several islands. The genus Corvus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective name for a group of crows is a "flock" or a "murder".

In Irish mythology, the Badb (Old Irish, pronounced [baðβ]), or in modern Irish Badhbh (Irish pronunciation: [bˠəu], Munster Irish: [bˠəiw])—also meaning 'crow'—is a war goddess who takes the form of a crow, and is thus sometimes known as Badb Catha ('battle crow'). She is known to cause fear and confusion among soldiers to move the tide of battle to her favoured side. Badb may also appear prior to a battle to foreshadow the extent of the carnage to come, or to predict the death of a notable person. She would sometimes do this through wailing cries, leading to comparisons with the bean-sídhe (banshee).

With her sisters, Macha and the Morrigan or Anand, Badb is part of a trio of war goddesses known as the three Morrígna.
