If you’ve ever wondered “What do grass snakes eat?”, you’re not alone. Grass snakes, also known as Ringed Snakes or Grass Snakes, are one of the most common species of reptile found in the United States. As their name suggests, they are often found in grassy areas, and their diet consists of a variety of animals, from mice and frogs to insects and other small creatures. In this article, we will uncover the diet of these slithery reptiles, and explore the different types of prey that make up their meals.

  • Frogs
  • Toads
  • Fish
  • Small mammals
  • Invertebrates
  • Birds
  • Eggs

Grass snakes are opportunistic feeders and the bulk of their diet consists of frogs and toads, but they also consume fish, small mammals, invertebrates, and birds. They occasionally eat eggs. They usually hunt at night, ambushing their prey. They also eat dead animals, especially if they are found near water.

Grass Snake Diet in Different Seasons

Grass Snake Diet In Different Seasons


In the spring, grass snakes feed on amphibians, such as frogs and toads, as well as small mammals and birds. They may also feed on earthworms, snails, and insects.


During the summer, grass snakes feed on a wide range of prey, including amphibians, small mammals, birds, earthworms, snails, and insects. They will also feed on fish and lizards.


In autumn, grass snakes eat small mammals, birds, amphibians, earthworms, snails, and insects. They may also feed on fish and lizards.


Grass snakes primarily feed on small mammals, birds, and amphibians in winter. They may also feed on earthworms, snails, fish, and lizards.

Do Grass Snakes Eat Other Snakes?

Do Grass Snakes Eat Other Snakes?

Grass snakes, also known as the European grass snake, are mostly nonvenomous and feed on amphibians, fish, and small mammals. They do not eat other snakes as they are not predators of their own species and do not have the right teeth or digestive systems to consume them.

Food Type Grass Snake Consumption?
Amphibians Yes
Fish Yes
Small Mammals Yes
Other Snakes No

Grass snakes are not aggressive and tend to flee when they come into contact with other snakes. They are primarily diurnal and will only hunt at night when the weather is warm. They prefer to live in wet, grassy areas and can often be found near water sources.

Do Grass Snakes Eat Frogs?

Do Grass Snakes Eat Frogs?
Grass snakes are non-venomous snakes that prefer to feed on small mammals, birds, eggs, and amphibians. They are opportunistic feeders and will take advantage of whatever food is available. In some cases, this can include frogs.

Frogs are a viable food source for grass snakes, and they may feed on them when they have the opportunity. However, grass snakes have been observed to prefer to eat other prey items more readily than frogs. Frogs are more difficult to capture and consume than other smaller prey, so grass snakes may only choose to eat frogs when other food sources are scarce.

Frogs may also be consumed for the additional benefits that they provide. Frogs provide a good source of fats and proteins, as well as other vitamins and minerals that can help a grass snake stay healthy.

Grass snakes will also consume frogs for their skin. Frog skin is rich in collagen and other proteins that can help a grass snake’s skin regenerate and stay healthy.

In conclusion, grass snakes do eat frogs, but they are not a preferred food source. Grass snakes may consume frogs when other food sources are scarce or when they need additional vitamins and minerals.

Do Grass Snakes Eat Fish?

Grass snakes are carnivorous and feed mainly on small mammals, amphibians, reptiles, and insects. Although grass snakes do not actively hunt for fish, they may occasionally consume them if they come across them. Fish are not a major part of the diet of grass snakes and they are capable of surviving without them. Grass snakes may opportunistically eat fish if they are available, but they will generally prefer other prey.

Do Grass Snakes Eat Birds?

Grass snakes are non-venomous and primarily feed on small rodents like voles, mice, and shrews. They are also known to eat toads, frogs, lizards, and fish. Though they may sometimes eat birds, they do not actively seek them out as a food source. Grass snakes prefer to eat animals that are easier to catch and can be swallowed whole. When eating birds, they are more likely to consume small chicks or eggs that are found in nests.

Frequently Asked Questions

What are some of the common foods grass snakes eat?

Grass snakes mainly feed on amphibians, particularly frogs and toads, but also consume lizards, small mammals and occasionally bird eggs. They also eat fish, earthworms, slugs and large insects, such as grasshoppers and beetles. Occasionally, they will also feed on carrion.

Where do grass snakes typically forage for food?

Grass snakes typically forage for food in grassy or marshy areas, near slow-moving water, and in wetlands. They also hunt in meadows and gardens, searching for amphibians, small reptiles, and small rodents. Grass snakes also consume a variety of invertebrates such as insects, slugs, and earthworms.

How can I identify a grass snake?

Grass snakes are typically bright green or yellow-green, with a distinctive black and yellow collar behind their head. They can grow up to 180cm in length and are usually found in grassy or marshy areas. Other identifying features include a white underside, round pupils, and a pointed tail tip.

What can I do to protect grass snakes and their food sources?

Protecting grass snakes and their food sources starts with understanding what they need to survive. Deploying artificial structures such as logs and rocks can provide them with the right kind of habitat. Minimizing the use of pesticides and herbicides can help protect their food sources, such as frogs, toads, and earthworms. Planting native wildflowers can also attract pollinators and beneficial insects that grass snakes feed on. Finally, educating others about the importance of grass snakes and their habitats is essential to long-term conservation.

Are Baby Grass Snakes More Likely To Eat Certain Types Of Food?

Baby grass snakes, or neonates, tend to eat smaller prey items than adults. They usually feed on invertebrates such as worms, slugs, and crickets. As they mature, they become more likely to eat larger prey like small rodents and frogs. Neonates may also be more attracted to certain types of food than others, such as live prey over dead or frozen prey.


Grass snakes are largely insectivorous, consuming a range of invertebrates including grasshoppers, beetles, caterpillars, and crickets. They may also consume small reptiles, amphibians, and mammals, as well as carrion. Grass snakes also feed on eggs, nesting birds, and fledglings. They also take advantage of garden bird feeders, consuming seed, grain, and nuts. Grass snake diets vary seasonally and regionally, likely based on the availability of prey. Grass snakes play an important role in controlling populations of their prey, but they may also benefit from their presence, as the snakes help keep rodent and insect populations in check.
