9. Barn Owl

When a male is interested in a female, he will give her certain gifts (like dead mice and screeching). If the female responds by croaking, she basically said “I do” and the two will form a beautiful married couple.

Barn owls are also loyal and dedicated creatures. According to the National Wildlife Refuge System in Willapa, Washington, these tiny creatures mate for life. The male brings food to the table while the female takes care of the nest. Teamwork at its finest.

10. Swans

Swans are very beautiful looking birds and very romantic at the same time. According to The Swan Sanctuary, they typically mate for life. “If a mate is lost, then the surviving mate will go through a grieving process like humans do.”

After the grieving process is over, the single swan will either remain alone, find another stretch of water to live on and possibly a new partner or re-join a flock. Additionally, males are very loyal and devoted, as they share egg incubation responsibilities with their partners.
