1. Macaroni Penguin

Macaroni Penguins, also known as Royal Penguins are known for having a monogamous mating system. As I’ve previously mentioned, 90 percent of bird species create indestructible bonds with their partners with whom they mate for life, but none of them can show affection like a Macaroni penguin does.

These adorable creatures form lifelong pairs and dance when they see their partner. The dance is called “an ecstatic display,” they puff their chests and move their heads side to side while making a gurgling-like sound.

The female usually lays two eggs, one smaller and typically not incubated, while the second and larger one is incubated by both parents for 34 days. After the baby is born, the father takes good care of the chick while the mother is searching for food.

2. Bald Eagle

While long-distance relationships seem almost impossible for us, humans, bald eagles are very good at it. They are solitary birds that fly alone during winter and migration, but they always return to the same partner each mating season. Also, the male helps the mother take care of their children after they’re born. How cute is that?

According to the National Audubon Society, the Bald eagle uses nest-building to consolidate their bond with their partner. “The pair continuously adds to the structure, so that after many seasons it assumes gargantuan proportions and stands as a symbol of their fidelity.”
