12 Common Animals That Eat Seeds (Granivores)

Animals that regularly eat seeds as part of their diets are called granivores. These animals can be birds, insects, or mammals, and serve important functions when it comes to dispersing plants across their habitat. There are several pets that enjoy eating various types of seeds as well.

12 Animals That Eat Seeds

Here are 12 common granivores found throughout North America, ranging from pets to wild animals, in no particular order.

1. Red Squirrel

  • Scientific name: Sciurus vulgaris
  • Diet: seeds, berries, vegetation

Red squirrels commonly feed on seeds and similar types of food. These small mammals are known for gathering food and leaving it hidden in piles around their nest. Squirrels do this in preparation for winter and hibernation. They are also able to store large amounts of seeds and other food inside pouches on their cheeks. These animals will eat seeds, as well as berries and vegetation.

2. Chipmunk

  • Diet: various seeds, nuts, berries, insects

Chipmunks are similar to red squirrels, but are smaller and are brownish with black markings. These rodents will eat various types of seeds, including pumpkin seeds, sunflower seeds, and sesame seeds. They can store food in their cheek pouches and will hide small piles to help them survive winter. Just like squirrels, chipmunks are known to hibernate during cold months.

3. Parrot

Parrots, both in the wild and when kept as pets, enjoy seeds from a range of fruits. These birds will eat cherry seeds, grape seeds, and raspberry seeds. Parrots can also eat grain. In the wild, they can also prey on insects, vegetables, and fruit. Pet parrots can be fed bird seed from the store, which is usually a mix of grain, pellets, and seeds.

4. Bean Weevil

  • Scientific name: Bruchinae
  • Diet: seeds, beans

There are plenty of insects that will feed on seeds. The bean weevil got its name because they prefer to feed on beans and bean seeds. These insects can become a pest in crop fields, and often exterminators need to be called to handle them. The larvae of these bugs are born inside bean seeds, making them capable of extensive crop damage.

5. Hamster

  • Scientific name: Cricetinae
  • Diet: seeds, nuts

Hamsters can be found in the wild, but have also become popular pets. Captive and wild hamsters enjoy seeds and nuts as a major part of their diet. Pet hamsters can easily be fed a mix of commercial food, while wild hamsters have to fend for themselves.

Like other rodents, their cheeks can hold a lot of food at one time, making it easier for them to forage. Wild hamsters might also eat vegetation and insects.

6. Ant

Ants are not the first animals people think of when thinking of animals that eat seeds. These insects feed on a variety of seeds and have even been credited with helping spread certain types of plants and flowers. Ants are even known to favor certain seeds over others, and won’t even bother with the seeds they don’t like.

Mice are similar to hamsters when it comes to their diets and their interaction with people. These rodents thrive in the wild but can be kept as pets. They are omnivores and opportunistic, so will eat nearly any plant or animal matter they come across.

A wild mouse will eat seeds, fruit, vegetation, or animal feces. Pet mice are even known to eat their own feces. As pets, they can be fed food mixed with seeds, grain, and pellets.
