Omnivores are animals that have wider food options, and they can eat and digest food materials from both herbs and animals. Most living organisms belong to the omnivore category. Moreover, organisms from all types of tropical levels are the main food sources of omnivore animals. Omnivore animals can be found everywhere on the planet.
The size of omnivore animals ranges from small insects like ants to higher organisms like humans.
List of omnivores animals and their food
Bear: Technically, bears are carnivores, but trophically, they are omnivores. That means they consume animals like insects, fish, small reptiles, etc.
Civet: It is essentially an omnivore that eats fruits, nuts, rambutan, chiku, and coffee, and also consumes insects and small animals.
Chipmunks: Chipmunks are also omnivores, meaning they eat different kinds of food materials. They aren’t restricted to specific tropical levels but consume what they get on their premises. They consume plant materials (fruits, nuts, and seeds) and animals, including baby mice, small birds, eggs of different birds, worms, and insects.
Coyote: It is an opportunistic omnivore that regularly eats wild animals and plants and typically eats whatever it gets. It hunts and scavenges small living creatures, ranging from small animals like mice to dogs.
Dog: Dogs are essentially omnivores, consuming food materials that are derived from both plants (grains and fruits) and animals (cats, rats, birds, etc.). Surprisingly, dogs eat grass and small plant leaves, especially wild dogs, which is quite common in most cases.
Human: Humans are the best examples of omnivore animals. Humans can hunt the animals and consume whatever they prefer to eat.
Hedgehog: Plant-derived materials like vegetables, fruits, and seeds, as well as animal-derived food materials like insects and other invertebrates, are the preferred food items for hedgehogs.
Monkeys: Monkeys also fall under the category of omnivorous animals, and they consume vegetables, seeds, fruits, nuts, and floral parts of plants. A few monkeys also eat animal-derived foods, especially eggs of birds, spiders, insects, and small reptiles.
Opossum: It is also known as a possum and eats dead animal matter, birds, rodents, frogs, eggs, and insects. It can also consume plant-based materials such as fruits and grains.
Pig: Pig is an omnivore and a foraging animal that majorly eats plant leaves, roots, fruits, and flowers. Moreover, it hunts small insects and fish.
Rat: A rat is an omnivore, that eats plant parts and small animals like insects, spiders, etc.
Squirrels: Most types of squirrels are omnivores, which means they prefer to eat both plant- and animal-based materials.
Birds: Omnivore birds eat both plant- and animal-based materials. Examples: Chicken, Duck, Sparrows, Crows, etc.
Fish: Omnivore fish eat both phytoplankton and zooplankton. Examples: Catfish, Parrotfish, Damselfish, etc.
