The Grease-Turtle Relationship: Do Greasy Diets Include Turtles?

Geese are waterfowl commonly found near rivers and lakes. They are known to migrate to warmer climates during winter and are considered pests by humans. While geese typically eat grass, grains, and aquatic plants, it is unclear whether they eat turtles. Some sources suggest that turtles are a threat to geese, with larger turtles capable of maiming or killing even adult geese. On the other hand, smaller turtles may be vulnerable to attacks by geese, especially when protecting their young. Therefore, while geese may not actively seek out turtles as a food source, interactions between the two species can lead to aggressive encounters, with the outcome depending on the size and behaviour of each animal.

Geese are omnivores

Geese are well-equipped to maintain a plant-based diet, and while they are capable of consuming small invertebrates and fish, this is not a significant part of their diet. They are considered borderline herbivores, and some species, like Canadian geese, are indeed classified as herbivores.

In the wild, the most common element of a goose's diet is grass, particularly short, fresh grass and new shoots. They also eat clovers, bluegrass, orchard grass, timothy, and bromegrass. In the water, they feed on the roots and stems of rushes and reeds, as well as sedges and their seeds. Watercress, seaweed, and kelp are also common in their diet.

During the fall and winter months, when less grass is available due to climate and location, geese consume more grains and seeds, as well as berries and wild fruits. They may also eat leftover crops, such as corn and beans, in agricultural fields.

While animal matter makes up only a small portion of their diet, geese may occasionally eat insects and small fish. However, when grazing on land, they will always choose grass over insects.

Turtles are a threat to geese

Turtles pose a significant threat to geese, particularly when the latter are young or have their goslings around. While geese are known for their aggressive behaviour, especially when defending their young, turtles can maim or even kill goslings and, occasionally, adult geese if the turtle is big enough.

Turtles have been observed to attack geese, and their powerful jaws can easily snap the necks of young geese, or even adults if the turtle is large. This poses a serious risk to geese, especially when nesting or raising young. In fact, turtles are considered one of the greatest threats to nesting geese, alongside other predators such as mink, coyotes, foxes, and raccoons.

While geese are typically larger and more aggressive than turtles, they are vulnerable when nesting or caring for their young. Turtles, on the other hand, are opportunistic predators and will take advantage of any weakness or distraction on the part of the geese. This makes turtles a significant threat to geese, especially during the nesting season.

The presence of turtles can also cause geese to abandon their nesting sites and move to safer locations. This can be detrimental to the survival of goslings, as it disrupts their natural habitat and can make them more vulnerable to other predators. Additionally, turtles may compete with geese for food sources, such as insects and aquatic vegetation, further increasing the tension between the two species.

In conclusion, while geese are generally not at high risk from turtles, the presence of turtles can significantly impact their behaviour and survival, especially during the critical nesting and rearing periods. Therefore, it is important to consider the potential threat that turtles pose to geese, and take appropriate measures to mitigate this risk.

Geese prefer grass

Geese are primarily vegetarians and thrive on a diet of grass and weeds, supplemented with nutritious treats. Grass is a staple food for geese, providing them with all the vitamins and minerals they need. However, it is important to note that grass is only nutritious when it is fresh and short, typically in the spring. Domesticated geese may need to be provided with mowed grass, while wild geese can fly to find fresh grass.

The typical diet of a goose consists mostly of grass, with small portions of grains, such as oats, wheat, or corn. In the warmer months, when grass is readily available, their diet can be up to 99% grass. Geese particularly enjoy young, tender, green grass and will also eat dandelion greens, clover, and other weeds. They can also be fed grass from your lawn, but it is important to ensure that no pesticides or chemicals have been used on the lawn.

Geese have an impressive appetite for grass, with an adult goose consuming up to 2.5 pounds of grass per day. They also require plenty of exercises, so it is essential to provide them with space to roam and graze. Geese are not suited to being penned up and will not thrive in such conditions.

In addition to grass, geese also enjoy a variety of herbs, such as thyme, oregano, parsley, and dill. They will also nibble on roses, blueberry or raspberry bushes, and even murder poor sunflowers, peonies, zinnias, or dahlias, chewing through their stems and leaving them for dead.

When grass is scarce, such as in the winter months, geese will need supplementary food. Hay, whole wheat, and cabbage are good options, along with other leafy greens like kale, lettuce, spinach, or Swiss chard. Geese also benefit from vitamins and supplements, such as niacin and Vitamin D, which can be added to their diet through brewers' yeast and Coop Kelp, respectively.

Geese can be aggressive

Geese are very territorial, with strong protective instincts, especially when it comes to their nests and babies. Male geese (ganders) are tasked with guarding the females and the nests while the eggs are incubated. They will patrol the area, honking, hissing, and sometimes becoming physically violent if they perceive a threat.

Geese often occupy urban areas due to the abundance of food and water and the low risk of predators. They are also commonly found near humans because people often feed them. This proximity and reliance on humans cause geese to lose their natural fear of people, making them more likely to attack if they feel their space is being invaded.

Geese have excellent vision and are highly observant of the eyes and body language of potential threats. They will respond aggressively if they feel you are intruding, and it is important to know how to respond to avoid an attack. It is recommended to maintain eye contact and face your body directly toward the bird, slowly backing away. Do not turn your back, run, yell, or make any aggressive movements, as this may trigger an attack.

While serious injuries from goose attacks are uncommon, they can happen, and it is best to avoid close encounters with geese, especially during their breeding season.

Geese are considered pests

Furthermore, geese are also considered pests due to their feeding habits. They feed on lawn grass and can overgraze, causing damage to lawns and landscapes. They also consume crops, reducing agricultural yields and increasing soil erosion. Geese are attracted to open areas with water bodies, such as rivers, ponds, and marshes, where they construct their nests. This habitat preference often brings them into close contact with human-altered areas, including golf courses, public parks, and agricultural lands. As a result, their feeding habits can cause significant damage to crops and impact the aesthetics of public spaces.

The noise created by geese is another factor contributing to their pest status. They are vocal birds and can be very noisy, particularly during their defensive or aggressive displays. This noise pollution can be disruptive to nearby residents or visitors in public areas. Additionally, geese are known to stalk and beg for food from humans, which is often a result of people disregarding policies against feeding wild animals. This behavior further reinforces their presence in human-altered environments and can lead to an increased perception of them as pests.

The establishment of breeding colonies in urban and cultivated habitats has led to the success of geese species, such as the Canada goose. Their adaptability to these environments, combined with a lack of natural predators, has resulted in their proliferation. This has, in turn, intensified their impact on human activities and ecosystems, reinforcing their classification as pests.
