Squirrels are opportunistic rodents who can feed on everything readily available in their surroundings to meet their requirements. These are omnivore animals, and they eat small insects, birds, and mammals apart from the plant-based diet and mushrooms.
Why Do Squirrels Kill Baby Birds? Squirrels can kill baby birds to satisfy their hunger during food shortage situations. In addition, they attack them because of increased energy requirements, and nesting site competition. American red squirrels and Eastern gray squirrels mostly kill birds and insects for meat sources. These rodents usually attack Sparrows, Warblers, Finches, Juncos, and Hummingbirds.
Birds that have their nest in less shrubby areas are more vulnerable to predator attack. In addition, it happens when their nest is present with a high population density of squirrels.
Why does a squirrel kill a baby bird?
Squirrels usually do not frequently kill baby birds because they take most of their diet from plant-based foods, nuts, and seeds. However, these rodents occasionally require meat to meet their protein and nutrient requirements.
Food shortage situation
They feed on nuts and seeds, but sometimes they kill the baby bird to meet their nutrient requirements. The issue usually occurs during food shortage situations and when they do not find enough sources to meet their requirements.
The food sources become limited in winter because of seasonal and climatic changes. These survivors and opportunistic feeders consume whatever is available in their surroundings.
The bird’s nests that are present in areas with high squirrel populations are at more risk. In addition, the risk of attack on nesting areas increases when there are limited food sources in the surrounding habitat.
Increased energy requirements
Their energy requirements vary according to different age groups and life stages. The nutrient requirements of the young ones differ from the adult species.
The pregnant and nursing squirrel’s daily requirements also increase because of the change in physiological processes in their bodies.
They need more nutrients to raise their young ones and provide them with sufficient food sources. They need nutrient and protein-dense food sources during these life stages.
Nesting site competition
These animals build their nest on the tree trunks and branches for shelter.
Sometimes, squirrels attack baby birds during nesting site competition. They can harm the babies and disturb their nests when they find a place suitable for them.
They damage their nests and claim that these specific areas are suitable for them. Nesting competition conflicts are common in them because of their territorial behavior.
They can attack them because they are aggressive and perceive them as a threat.
A quick source of vitamins and minerals
Sometimes, squirrels are predators of baby birds but do not intentionally seek them. They only kill them when hungry and do not find their parents in the surroundings.
They feed on them because of the protein and fat sources, which are helpful in their growth and allow them to sustain their activities respectively.
In addition, it provides vitamins and minerals, including iron, calcium, and vitamins D, E, and K. It is also necessary to keep in mind that squirrels are predominantly herbivore animals, and they take these diets occasionally.
How do squirrels find baby birds?
Squirrels are intelligent animals that use their cognitive abilities, visual cues, and sense of smell to find baby birds. They can spot the different nesting spots on the trees during food foraging.
In addition, they can also find them when they make a nest in your buildings. They can also attack the baby birds when they are alone and their mothers are not there. Mother birds mostly do not leave their babies unattended because of the fear of predator attack.
Sometimes, they have to go outside to gather food for them. Squirrels can attack them when their mothers leave them unattended.
In addition, the babies sometimes fall from their nests, and their predators can find them quickly.
What type of squirrel kills baby birds?
Their natural diet consists of plant-based fresh foods, nuts, and seeds. In addition, some of their species also feed on baby birds and mammals.
Eastern gray, red, and fox squirrels are famous for their preying nature. These species primarily feed on plant sources, nuts, and seeds, but they also rely on meat sources when they are hungry.
In addition, they attack the nesting areas because of their food-hoarding behaviors. Moreover, the issue comes because of their aggressive and territorial nature.
What type of baby birds do squirrels kill?
Some of their species preferably kill the baby birds to take the nutrients from them. Plant-based diets do not provide sufficient fat and protein to these rodents, so they attack different animals to meet their needs.
However, squirrels do not attack adult birds because of their large size. They attack their young ones, kill them, and eat their carcass.
They usually feed on sparrows, Warblers, Finches, Juncos, and hummingbirds. In addition, they also attack the birds that are present in their surrounding habitat.
How do I protect my baby birds from squirrels?
You have to take several preventive measures to protect the baby birds and their nesting area from the squirrels. It is necessary to restrict their entry into your backyards so they cannot approach the nesting areas.
It is necessary to select the correct spot for the placement of the nesting box. Place them high on the trees and ensure that there are no branches in the nearby areas.
I prefer to install the predator guards on the base of the tree trunk so these rodents cannot climb there. Trim the branches of the trees so they cannot jump on these branches and easily find the nest box.
You can use deterrents like hot pepper, coffee grounds, garlic, and essential oils near the nesting area to repel the rodents. One of my friends told me that he always uses squirrel-proof feeders for their birds that automatically close off the feeding spots when they detect their presence.
In addition, it is also necessary to provide alternative food sources to squirrels so they cannot kill the birds to satisfy their hunger.
You should also prefer the nesting area and shift them to a safe location if you find any threatened species in their nearby areas.
Do squirrels eat the eggs of birds?
Squirrels can also eat the birds’ eggs if they are easily available in their surroundings. These are natural climbers and climb on trees to find food sources.
They need some energy while climbing trees to restore their energy levels. They can easily access the nests of the birds and eat the eggs.
These animals easily access the nests when mother birds are not present there. Mothers usually spend most of their day in the nest but occasionally go outside to find food.
In addition, eggs are highly nutritious food for these animals. It provides a sufficient amount of protein and fat, which helps in their growth and development.
Moreover, these animals also eat eggshell because it is rich in calcium and helps in body processes and the strengthening of various organs.
Eating baby bird eggs is not their natural diet, but they feed on them during hunger situations and scarcity of food sources.
These are survival animals, and their diet mainly consists of food sources readily available in their surroundings. The diet of their different species varies according to their environment and natural habitat.
Fox squirrels and red squirrels are opportunistic feeders, and they mainly raid the bird’s nest and steal eggs from them when mothers leave them unattended.
