As you can imagine, there are more than 10,000 species of birds in the world, and their diets and what they eat vary widely. But which birds are omnivores?
Many bird species are considered omnivorous, including crows, ducks, thrushes, blackbirds, woodpeckers, orioles, cranes, pheasants, gulls, robins, starlings, and chickens. The diet of these birds varies widely, depending on the food sources in and around their habitat.
Although the birds listed above are considered omnivorous, some of them are stronger omnivores than others. However, none of them are picky and will eat a mixture of plant and animal foods.

Woodpeckers are strong omnivores
What is an omnivore?
Omnivore is a term for animals and birds whose diets typically include large amounts of plant and animal foods. The adjective to describe these animals and birds is omnivorous.
What Do Omnivorous Birds Eat?
The diet of omnivorous birds varies widely, depending on the abundance of certain food sources within their range and habitat.
Some plant food eaten by omnivorous birds Includes seeds, grasses, fruits, nuts, grains, nectar, pollen and buds.
Omnivorous birds eat animals including Insects, snakes, carrion, mammals, rodents, lizards, fish, eggs and crustaceans.
To be considered omnivorous, birds don’t need to eat every plant or animal food. However, the diet does need to include a lot of animal and plant foods.
Dietary categorization is usually only done when birds reach the adult stage, since the chick and juvenile stages of their lives may eat vastly different diets. This is because young birds depend on foods rich in nutrients and protein, which aid in growth and development.

Which birds are omnivores?
Technically, most birds can be considered omnivorous, since most birds include insects as part of their diet, since they provide a reasonable amount of protein.
However, birds that eat only a small portion of insects and other animal material and whose diet consists primarily of plant foods are generally not classified as omnivores.
Birds that are generally classified as omnivorous consume a more balanced balance of plant and animal foods in their diets.
Examples of birds that are considered omnivorous include:
- crow
- Duck
- woodpecker
- thrush
- Robin
- pheasant
- turkey
- black bird
- oriole
- freckle
- seagull
- grouse
- crow
- magpie
- Jess
Are birds omnivorous year-round?
Omnivorous birds must vary their diets primarily based on the time of year and available food sources.
This means that insects can be a major source of food during spring and summer, as insect populations proliferate and there are plenty around.
As summer draws to a close, insect populations may start to decline, replaced by omnivorous birds that often feed on fruits that are more readily available as crops mature. Grains and seeds may be eaten more frequently in the fall, as they are generally more readily available.
During winter, omnivorous birds become less picky and will eat most of what they can, as food may be scarce during this time. Many birds can store food such as grains and seeds for this time.
The highly variable diet and adaptability of omnivorous birds means that they generally have a better chance of survival because of the wider range of food choices they can and will eat. This is more pronounced for birds that are resident and do not migrate during the cold winter months.

Not only does the weather determine what omnivorous birds eat, females also often consume foods that are higher in calcium during the breeding season. This is because it promotes healthy egg development.
When birds are moulting, more animal food can be consumed because the higher levels of protein and nutrients greatly promote the development and growth of new feathers.
Migrating birds require a high-calorie and high-fat diet both before and during migration. This extra energy is crucial for birds to successfully complete long-distance migrations.
Chicks and young birds typically eat more animal material in their diets. This is because growth and development require high levels of protein and nutrients at such a critical time in their lives.
Omnivorous birds often switch their diets to a completely herbivorous diet when they reach a more mature stage in their lives because they do not depend on as much protein and nutrients each day. At this point, they are no longer technically considered omnivorous.
What does it take to feed omnivorous birds in the garden and backyard?
Since birds eat a variety of diets, this means that having a mix of animal and plant foods at your feeders will cater to all species and attract a wider variety of hungry birds.
Animal-Based Garden Bird Food That includes mealworms, crickets, and anything that includes fatty base oils. Minimizing the amount of insecticides and insecticides means there are plenty of insects and rodents for birds to prey on.
some examples of Plant-Based Backyard Bird Food Includes mixed seeds, sunflower seeds, niger seeds, peanut butter, fruit slices, sugar or nectar water, berry bushes, fruit trees, seedflowers, and pumpkin seeds.
A mix of the above foods in your feeders will not only provide birds with a rich food source, but will also attract a diversity of bird species in your backyard.
Having many different types of feeders also helps attract more birds, since different types are easier to use than others for specific birds.
Make sure feeders are cleaned regularly to stop the spread of any disease and make them less attractive to rodents and vermin. Also, consider installing barriers to keep unwanted visitors out.

Different Bird Feeders Attract Different Birds
Are eagles omnivores?
Eagles are not omnivores, but are often classified as carnivores because their diet consists mainly of other animals. Eagles will only eat vegetable vegetation to prevent starvation or to aid digestion; however, this is very rare.
Are owls omnivores?
Most owls are carnivorous, feeding mainly on small mammals including mice and rabbits, lizards and snakes. There are some exceptions to this rule, and small owls like burrowing owls also sometimes eat seeds and fruit.
Owls rarely eat plants, and when they do, it’s usually in desperation to avoid starvation because there’s no other food around. It can also help with digestion, but this is rather unusual behavior.
Are all birds of prey omnivores?
Birds of prey are not omnivorous, but are all classified as carnivorous. This is because most of the food they prey on and consume is the meat of other animals. Most raptors hunt reptiles, mammals, other birds, and fish for food.
Are birds herbivores, carnivores, or omnivores?
Birds can technically be herbivores, carnivores, and omnivores. Birds that eat only plant material (such as hoatzins) are classified as herbivores, birds that eat a mixture of plants and animals (such as crows and many others) are omnivorous, and birds that eat only meat (such as owls, hawks, and hawks) Classified as a carnivore.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
