Most Loyal Animals to Their Mates

The most loyal animals are those which have the strongest bonds to their mates, although this loyalty often extends to their large family group. AnimalWised looks at these loyal animals which are often monogamous, meaning they only have one mate at a time. Some animals are so loyal to their mates, they will never find another during the rest of their lifetime. There are many evolutionary advantages to remaining loyal with one mate, although other species have developed other ways to better survive.

Many of the most loyal animals to their mates have become symbols of faithfulness and loyalty for humans. Discover these faithful animals with photos as we look at the most loyal animals to their mates.

Parakeets are social animals that feel lonely and sad when they have no company. It is one of the most faithful animals to their mate.

Beaver

Beavers are monogamous animals that it will stay loyal until their mate dies. Both faithful parents work together, maintaining the nest, creating large burrows and supporting each other in order to survive.

When they reach adulthood, young beavers leave the colony to form a new one. When there is a shortage of food, beavers will remain with their family waiting until food is more copious. Even when they do become independent, it has been observed that beavers don't move far away from their parents when they are establishing a new colony. This means they are one of the most loyal animals for life.

Crested penguins

In the summer, crested penguins return to the place where they were born in order to meet a suitable partner to form a loyal and lifelong couple. Mates which are already paired up return to Antarctica to the exact spot where they last nested. In fact, crested penguins can be very aggressive if they see another penguin trying to mate with their partner.

After a male and female successfully mate, they will both take care of their eggs and young. This shows that this animal loyalty is for all the family, not just their mates.
