Woodpeckers and opossums are both omnivores, but their diets differ in many ways. Opossums are scavengers and will eat practically anything they can find, including insects, small animals, and even human food scraps. On the other hand, woodpeckers are less picky and often adjust their diets based on what is available in their environment. They eat a variety of foods, including insects, fruits, and nuts, and are known to enjoy treats like oranges, grapes, and apples. While opossums might raid your garbage cans, woodpeckers can be attracted to your backyard with the right feeders and food. Understanding the dietary habits of these creatures can provide insight into their unique adaptations and behaviours in their respective environments.

What You'll Learn
Woodpeckers eat insects, fruit, nuts and sap
Woodpeckers are omnivores, and their diet consists primarily of insects. They feed on both plant and small animal matter, depending on the species. Some species eat only a few types of prey, while others are much more generalistic and will eat just about anything. For those that eat mostly insects, their diet usually consists of insect larvae, beetles, and ants, as well as grasshoppers, spiders, wasps, millipedes, crickets, and more.
Woodpeckers are particularly adept at extracting wood-boring insects, using their strong bills to excavate holes and their long, barbed tongues to capture prey. They can also detect prey within wood by listening for sounds, indicating where excavation might be fruitful.
While insects are the mainstay of their diet, woodpeckers are flexible in their food choices, especially during different seasons. They incorporate fruit, nuts, seeds, and sap based on seasonal availability. During the non-breeding season, some species, such as flickers, incorporate fruit and nuts into their diet. They eat most of the fruits humans do, including oranges and other citrus, apples, strawberries, and many more. They also eat wild fruits and berries.
Sapsuckers, a type of woodpecker found only in North America, have evolved to rely heavily on tree sap as a key component of their diet. They create rows of small, shallow holes, called “sapsucker wells,” in the bark of trees to access the sap flowing in the tree’s phloem, the tissue responsible for transporting sugars. They then use their specialized tongues to lap up the sap.

Opossums are scavengers, eating insects, small animals and fruit
Opossums are scavengers, eating insects, small animals, and fruit. They are omnivores, meaning they eat a wide variety of foods. Opossums are opportunistic and will eat practically anything they can find to stay alive. This includes insects, ticks, small rodents, frogs, birds, and berries. In residential areas, opossums will scavenge for vegetables, fruits, garbage, birdseed, and pet food. They also eat fresh meat and roadkill.
Opossums are most active at night, constantly moving in search of food. They have a keen sense of smell and hearing, which helps them find meals. They also use their prehensile tails and opposable thumbs to climb trees in search of food. Opossums are known to raid gardens, chicken coops, garbage cans, and even human homes in their search for nourishment.
The diet of an opossum changes slightly depending on the season and environment. In the summer, they eat more insects, while in the winter, they consume more small mammals. Opossums also need high amounts of calcium, so they eat the skeletal remains of small animals and roadkill.
Opossums are beneficial to have around as they act as natural pest controllers, helping to decrease the number of rodents, cockroaches, ticks, snails, and slugs. They also play a role in seed dispersal and ecosystem cleaning by consuming carrion, which prevents the spread of disease.

Woodpeckers are adaptable and opportunistic eaters
Woodpeckers are primarily insectivores, but they are adaptable and opportunistic eaters. They are usually found in polar climates and belong to the Picidae family of birds. Their most distinctive feature is their method of hunting, which involves hammering their beaks into tree bark to extract insects and insect larvae. This behaviour also gives them access to tree sap, another important food source for woodpeckers.
Woodpeckers are highly adaptable and can feed on a variety of food sources depending on the species and region. Some species have a more restricted diet, while others are generalists and will eat almost anything. Larger woodpecker species may also feed on small animals, such as lizards, bird eggs, and even small mammals.
Their diet consists of small invertebrates, arthropods, fruits, nuts, and sap. They are skilled at extracting insects hiding in hard-to-reach places, thanks to their long beaks. This anatomical advantage allows them to feed on wood-boring insects, spiders, and berries.
The adaptability of woodpeckers is further demonstrated by their ability to feed on plant matter and small animal prey. They are true omnivores, consuming both plant and animal food sources. This adaptability ensures their survival in various habitats and environmental conditions.
In summary, woodpeckers are highly adaptable and opportunistic feeders. Their diet primarily consists of insects and plant matter, but they will take advantage of various food sources depending on their specific needs and the availability of resources in their environment.

Opossums require calcium and are susceptible to poor diets
Opossums are opportunistic scavengers and omnivores, meaning they will eat a wide variety of foods. Their diet includes insects, ticks, small rodents, frogs, birds, and berries. In residential neighbourhoods, opossums will forage for vegetables, fruits, garbage, birdseed, and pet food. They will also eat fresh meat and roadkill.
Opossums require a certain amount of calcium and phosphorous in their diet, with a specific calcium-to-phosphorous ratio (Ca:P) of 1.5:1. If they do not receive an adequate amount of calcium, they can develop metabolic bone disease (MBD), a complex and life-threatening disease that causes outward signs of bone crippling, similar to rickets. MBD can cause a range of issues, including skeletal deformities, an inability to use the mouth, and organ failure, eventually leading to death.
The disease is caused by a low calcium diet, which results in a decrease in calcium in the blood. This triggers the parathyroid gland to secrete parathyroid hormone (PTH) to prevent plasma calcium from falling too low. While this helps maintain blood calcium levels, it also weakens the bones as minerals are lost, increasing the risk of fractures.
To prevent and treat MBD, it is crucial to correct the opossum's diet and provide a high-quality, balanced diet with sufficient calcium and the proper Ca:P ratio. Calcium-rich foods such as low- or non-fat yogurt, kale, cabbage, collard greens, and bok choy are recommended. It is generally advised to avoid calcium supplements, as they can cause hypercalcemia and complicate the disease.
Opossums are susceptible to poor diets due to their scavenging nature and their need for specific nutrient ratios. A poor diet can lead to serious health issues such as MBD, highlighting the importance of proper nutrition for these animals.

Woodpeckers and Opossums both eat ants
Woodpeckers and opossums are omnivores, and their diets consist of plants, small animals, and insects. Opossums are scavengers and will eat a wide variety of foodstuffs. Their diet includes insects, ticks, small rodents, frogs, birds, and fruits. In residential areas, they will also eat vegetables, garbage, birdseed, and pet food. Opossums depend on their sense of smell and touch to find meals. They use their prehensile tails and opposable thumbs to climb trees in search of food.
Woodpeckers, on the other hand, are known for pecking at trees with their long beaks to access tree sap and insects. Their long beaks allow them to extract insects hiding in hard-to-reach places. While the diet of woodpeckers and opossums overlaps in many areas, both creatures are known to eat ants. Ants are a common food source for many species of woodpeckers, and opossums also include them in their diet when available.
Woodpeckers primarily feed on insects, and ants are a favorite snack for many species. They use their beaks to extract ants from logs, trees, and other crevices. Some species of woodpeckers have been observed feeding on ant colonies, where they peck at the ground to disturb the ants and then quickly capture them with their beaks. Ants provide a good source of protein and energy for woodpeckers, especially during the breeding season when their nutritional needs are higher.
Opossums, being opportunistic feeders, will also take advantage of ant colonies when they come across them. They may raid ant nests or feed on ants that are attracted to the fruits they consume. While ants may not be their primary food source, opossums will consume them as part of their diverse diet. Additionally, opossums are known to eat the skeletal remains of small animals to meet their calcium needs, and ants can contribute to this requirement.
Both woodpeckers and opossums play a role in controlling ant populations in their respective habitats. By feeding on ants, they help maintain ecological balance and may even reduce the risk of ant infestations in certain areas. This aspect of their diet can be beneficial to human populations, especially in residential areas where effective pest control is important. Overall, the dietary preferences of woodpeckers and opossums, including their mutual enjoyment of ants, provide insight into the feeding habits of these fascinating creatures.
