Woodpeckers and opossums have very different diets, despite both being omnivores. Opossums are scavengers and will eat practically anything they can find, including insects, small animals, and human food scraps. Woodpeckers, on the other hand, are less picky and will eat insects, sap, and fruit, but they do not typically scavenge. They are also able to eat food that other birds cannot reach. This article will explore the diets of these two creatures in more detail, highlighting the differences and similarities between them.
| Characteristics | Opossums | Woodpeckers |
|---|---|---|
| Diet type | Omnivorous | Insectivorous |
| Diet | Insects, ticks, small rodents, frogs, birds, berries, vegetables, fruits, garbage, pet food, fresh meat, roadkill, small mammals | Insects, insect larvae, tree sap, ants, wild berries, fruits, nuts, seeds, plant foods |

Opossums are omnivores, eating insects, rodents, birds, eggs, fruits, and plants
Opossums are omnivores, meaning they eat a variety of foods, including insects, rodents, birds, eggs, fruits, and plants. They are scavengers and will eat almost anything to survive, including carrion and roadkill. Opossums are known to raid garbage cans and bird coops for nourishment, and they have a particular fondness for fruits that are close to rotting, as these attract insects, another food source.
Opossums are also known to eat ticks, frogs, snakes, slugs, shellfish, and small mammals, such as mice. They will also consume birdseed, pet food, and vegetables when foraging in residential areas. The opossum diet changes slightly depending on the season. For example, they tend to eat more insects in the summer and more small mammals in the winter.
Opossums are marsupial mammals, belonging to the Animalia kingdom, and are predominantly found in America. They are considered "living fossils," and while they are not aggressive, they are often considered pests due to their tendency to disturb household pets, destroy gardens, transmit diseases, and create nests in attics, walls, and basements.
The Virginia opossum is the only species found in the United States and Canada, but opossums can also be found in Central and South America, where they originated. Opossum pelts have long been part of the fur trade, and opossum oil, or possum grease, is used as a folk remedy and for arthritis treatment.

Opossums are opportunistic scavengers, feeding on human food scraps and rummaging through bins
Opossums are opportunistic scavengers, feeding on a wide variety of foodstuffs, including human food scraps and rummaging through bins. They are omnivores, and their diet includes insects, rodents, small mammals, birds, and plants. Opossums are known to raid garbage cans and human homes for nourishment, eating leftover food from bins and even pet food. They also eat fruits, with a preference for those that are close to rotting, as these attract insects, another food source for opossums.
Opossums are members of the marsupial order Didelphimorphia, and they are endemic to the Americas. They originated in South America and are now found in North and South America. The Virginia opossum is the only species found in the United States and Canada. These mammals are considered "living fossils," with the oldest opossum fossils dating back to the early Miocene epoch, approximately 20 million years ago.
As scavengers, opossums play an important ecological role in cleaning up the environment by consuming decaying matter and other waste. They have a strong sense of smell and touch, which helps them locate food. Opossums are also known for their prehensile tails and opposable thumbs, which they use to climb trees in search of food.
The diet of opossums varies depending on the season and their environment. In the summer, they tend to eat more insects, while in the winter, they consume more small mammals. Opossums are adaptable and can survive on a diverse range of foods, allowing them to inhabit different types of environments.
In addition to human food scraps and insects, opossums also feed on birds, bird eggs, and even carrion or roadkill. They are known to eat the skeletal remains of small animals to meet their calcium needs. This adaptability in their diet and their ability to scavenge effectively contribute to the survival and success of opossums in various habitats.

Woodpeckers are adaptable, eating insects, sap, and fruit
Woodpeckers are omnivores, and their diet consists primarily of insects. They are adaptable, however, and will also eat fruit, nuts, seeds, and sap, depending on the season.
In spring, after a long winter, woodpeckers eat sweet tree sap and various fruits and berries. In late spring and summer, their diet consists mainly of insects. In winter, they change their diet to nuts and berries, as insects are scarce during this time.
Some woodpecker species, like Flickers, incorporate fruit and nuts into their diet during the non-breeding season. They are also known to eat plant fruits, including oranges and other citrus, apples, strawberries, and many wild fruits and berries.
Sapsuckers, as their name suggests, are specialized for feeding on tree sap. They drill wells in trees to access the sap and also consume insects trapped in it. The Yellow-bellied Sapsucker, for instance, eats tree sap, wood-boring insects, and ants. They also consume inner bark and cambium (the innermost layer of the bark of a tree trunk or a branch).
While insects are the mainstay of the woodpecker's diet, they are flexible in their food choices, especially during different seasons. They eat most types of insects and their larvae, including beetles, ants, plant lice, caterpillars, wood-boring larvae, spiders, and more.
Some larger woodpecker species also eat bird eggs, lizards, and even small mammals. Each species has a different diet, which varies based on region and preference.

Woodpeckers are least picky in the bird family, eating or drinking their food
Woodpeckers are known for their distinctive behaviour of pecking at trees with their long beaks to access tree sap and insects. This behaviour is linked to their diet, which is highly varied compared to other birds. While most bird species have specific dietary preferences, woodpeckers are generalists, consuming a wide range of plant and animal matter.
Woodpeckers are primarily insectivores, and their long beaks enable them to extract insects and insect larvae from trees effectively. Their diet includes a variety of insects such as beetles, ants, grasshoppers, spiders, wasps, millipedes, and crickets. Additionally, woodpeckers also feed on small animals, including lizards and even small mammals, depending on the species.
The woodpecker's diet is not limited to insects and small animals. They also consume plant-based foods such as fruits, nuts, and grains. Some species have a particular preference for tree sap, which can be easily accessed with their long beaks. This preference for tree sap is a distinguishing feature of their diet.
The dietary habits of woodpeckers can vary based on their region and preference. Different woodpecker species have different dietary habits, and their food sources may overlap or be unique to their range. While some species may have specific dietary preferences, others are more generalistic, showcasing the adaptability of these birds.
The woodpecker's behaviour of pecking at trees is not just a hunting strategy but also serves a nutritional purpose. By pecking at trees, they gain access not only to insects but also to the tree sap, which provides them with essential nutrients. This behaviour is so integral to their survival that their habitat is largely dependent on the availability of trees for foraging.

Woodpeckers are smart, storing food for later
Opossums and woodpeckers are both omnivores, but their diets differ. Opossums are scavengers, eating a wide variety of foods, including insects, small mammals, birds, and plants. On the other hand, woodpeckers primarily eat insects and other invertebrates, though their diet can vary depending on the species. Some larger woodpecker species also eat small mammals and bird eggs.
Woodpeckers are intelligent birds, and some species are known for their unique food storage habits. While some woodpeckers may occasionally cache food, Acorn Woodpeckers are renowned for their dedicated hoarding behaviour. They actively drill holes in trees, telephone poles, or fence posts to create specialised storage sites called "granaries". These granaries can hold an extensive amount of food, with one study documenting over 60,000 acorns in a single granary.
Red-headed and Red-bellied Woodpeckers also store food in tree crevices, cracks, or under loose bark. The Red-headed Woodpecker is unique in covering its stored food, usually with bits of wood. They store leftover food, such as acorns and beechnuts, and even grasshoppers, which they keep alive in tight crevices.
The caching behaviour of woodpeckers provides a significant survival advantage, especially during periods of food scarcity, such as winter. By storing food, they can maintain their energy levels and survive harsh conditions. This behaviour is particularly beneficial for non-migratory species that remain in their territories year-round.
The cooperative breeding system of Acorn Woodpeckers is closely linked to their remarkable food storage habits. Their communal approach to filling, maintaining, and defending their granaries ensures a reliable food supply for the entire group. This social complexity and adaptation to future needs are fascinating aspects of Acorn Woodpecker behaviour.
