Hummingbirds and squirrels often share the same backyard, leading many to wonder if the larger rodent poses a threat to the tiny bird. Squirrels are opportunistic omnivores, and understanding their dietary habits provides a factual explanation for this predatory relationship. This knowledge is important for anyone seeking to create a safer environment for hummingbirds.
The Definitive Answer: Squirrel Predation on Hummingbirds
The direct answer to whether squirrels consume hummingbirds and their eggs is yes, they can, but this predation is almost always opportunistic rather than active hunting. Squirrels are classified as omnivores, meaning they will consume both plant and animal matter when the opportunity arises. Adult hummingbirds are typically too quick and agile to be caught by a squirrel, making an attack on a healthy, mature bird exceptionally rare.
The primary vulnerability lies with the nest contents, specifically the eggs or the helpless nestlings and fledglings. A hummingbird’s nest is susceptible to raiding if a squirrel discovers it while foraging. Common tree squirrels, such as the Eastern Grey Squirrel, are the species most often implicated in these incidents. The motivation for this behavior is a quick source of protein and fat, which is particularly valuable during the spring and summer breeding seasons when caloric needs are high.
While adult birds are generally safe, the defenseless young represent an easy meal that supplements the squirrel’s largely plant-based diet. This predation is a natural reality of the wild where any high-protein food source is exploited by opportunistic feeders.
Typical Squirrel Dietary Habits and Opportunism
Squirrels are widely known for their primary diet of nuts, seeds, and acorns, but this perception as strict herbivores is incomplete. Their daily foraging naturally includes a diverse range of plant materials, such as tree bark, fungi, fruits, and leaf buds. Protein sources like insects, caterpillars, and grubs are readily incorporated into their diet, providing necessary nutrients often lacking in plant matter alone.
This flexibility ensures their survival, particularly when their preferred food sources become scarce. The consumption of bird eggs or nestlings is an extension of this opportunistic drive for protein, especially during periods like late winter or early spring. This behavior is not a consistent, premeditated activity but rather an adaptable response to environmental conditions and caloric requirements.
The need for protein is especially pronounced in female squirrels during gestation and lactation. A vulnerable nest represents an easily accessible, concentrated source of high-quality animal protein that helps support the energy demands of reproduction.
Strategies for Protecting Nests and Feeders
Protecting hummingbirds involves minimizing the opportunities for squirrels to access their nests and feeders. One of the most effective strategies for feeder protection is placement, which should be at least ten feet away from any structure a squirrel can use as a launch point, such as trees, fences, or roofs. Attaching a specialized baffle, a dome or cone-shaped barrier, above or below the feeder pole can prevent squirrels from climbing up.
To further deter squirrels from the general area, consider offering a dedicated feeding station with nuts and seeds placed far away from the hummingbird feeders. This action can divert their attention and foraging efforts away from the areas where hummingbirds are active. If squirrels are raiding nearby seed feeders, using suet or seed treated with capsaicin (hot pepper) is effective, as birds cannot taste the heat, but mammals will be discouraged from eating it.
When protecting nests, direct human intervention is generally not recommended, as it can cause the mother to abandon the site. Instead, focus on creating a naturally safe yard environment by encouraging dense, thorny shrubs and trees. Hummingbirds often select these locations for nesting because the thick foliage and sharp thorns provide a natural barrier against climbing predators like squirrels.
