Frugivorous birds, or frugivores, are fruit-eating specialists. Orioles, waxwings, and toucans are all frugivorous and will eat fruit, berries and fruit-flavored jelly in the backyard. Many other birds will also sample fruit, including thrushes, grouse, quail, jays, wrens, tanagers and even some finches and sparrows. Many tropical birds also eat fruit. Frugivorous birds may be considered pests in orchards. A granivore eats grains or seeds primarily. Many birds are granivorous, including many sparrows and finches. These are easy birds to attract to the backyard with different types of birdseed. Planting seed-bearing flowers in the yard or opting for ornamental grasses are easy ways to provide natural foods for granivores.

Many of these birds also eat large amounts of weed seeds or spilled grain in fields. Insectivorous birds are specialized carnivores that feed on insects, from gnats to mosquitoes to dragonflies. Flycatchers and warblers are insectivorous, and most birds will eat insects to feed hatchlings sufficient protein for healthy growth. Other types of birds that are primarily insectivorous all their lives include swallows, swifts, martins, dippers, and nighthawks. A molluscivorous bird feeds on mollusks such as snails, slugs or oysters. Many shorebirds are molluscivores and will forage at low tide for clams and oysters. Other molluscivorous birds forage in tidal flats or swamps. Limpkins are mollusk specialists, and many other wading birds and corvids also eat mollusks.

A molluscivorous bird may drop its food from a great height to help crack tough shells, so the meat is easier to access. Mucivorous birds feed on the mucus of plants and trees, namely sap. Few birds are solely mucivorous, but woodpeckers, waxwings, kinglets, and warblers all have a mucivorous component to their diets. Birds may drill into trees to release sap to sip, or they may take advantage of larger wounds on trees to access sap with less effort. Other birds will pick insects out of sap, but don't eat the sap and wouldn't be considered mucivores.

A nectivore feeds on flower nectar, and the most well known nectivorous birds are the more than species of hummingbirds in the world. Other popular nectivores include honeycreepers and sunbirds, and nectivorous birds will visit both flowers and nectar feeders. Many other birds will also eat some nectar, including finches, woodpeckers, chickadees, and orioles. An ophiophagous bird is a snake-eater, a specialized type of skilled carnivore. The snake eagle family of birds are ophiophagous, and the secretary bird is one of the most well-known snake-eating birds. Many larger wading birds, such as herons and egrets, will also eat any snakes they can catch.

Occasionally, it is found that animals historically classified as carnivorous may deliberately eat plant material. For example, in , it was considered that American alligators Alligator mississippiensis may be physiologically omnivorous once investigations had been conducted on why they occasionally eat fruits. It was suggested that alligators probably ate fruits both accidentally and deliberately. Likewise, many mosquito species in early life eat plants or assorted detritus, but as they mature, males continue to eat plant matter and nectar whereas the females such as those of Anopheles , Aedes and Culex also eat blood to reproduce effectively.

Although cases exist of herbivores eating meat and carnivores eating plant matter, the classification "omnivore" refers to the adaptation and main food source of the species in general, so these exceptions do not make either individual animals or the species as a whole omnivorous. For the concept of "omnivore" to be regarded as a scientific classification , some clear set of measurable and relevant criteria would need to be considered to differentiate between an "omnivore" and other categories, e. Various mammals are omnivorous in the wild, such as species of hominids , pigs , [44] badgers , bears , coatis , civets , hedgehogs , opossums , skunks , sloths , squirrels , [45] raccoons , chipmunks , [46] mice , [47] and rats.

Most bear species are omnivores, [51] but individual diets can range from almost exclusively herbivorous hypocarnivore to almost exclusively carnivorous hypercarnivore , depending on what food sources are available locally and seasonally. Polar bears are classified as carnivores, both taxonomically they are in the order Carnivora , and behaviorally they subsist on a largely carnivorous diet. Depending on the species of bear, there is generally a preference for one class of food, as plants and animals are digested differently.

Canines including wolves , dogs , dingoes , and coyotes eat some plant matter, but they have a general preference and are evolutionarily geared towards meat. Like most arboreal species, squirrels are primarily granivores, subsisting on nuts and seeds. For example, the American eastern gray squirrel has been introduced to parts of Britain, continental Europe and South Africa. Its effect on populations of nesting birds is often serious because of consumption of eggs and nestlings. Various birds are omnivorous, with diets varying from berries and nectar to insects , worms , fish , and small rodents. Examples include cranes , cassowaries , chickens , crows [56] and related corvids , kea , rallidae , and rheas. In addition, some lizards , turtles , fish such as piranhas and catfish , and invertebrates are omnivorous.

Quite often, mainly herbivorous creatures will eagerly eat small quantities of animal food when it becomes available. Although this is trivial most of the time, omnivorous or herbivorous birds, such as sparrows, often will feed their chicks insects while food is most needed for growth. Similarly, monkeys of many species eat maggoty fruit, sometimes in clear preference to sound fruit. From Wikipedia, the free encyclopedia.
