Birds are incredibly romantic and life-loving animals, and many are famous for their love stories. Some birds exhibit remarkably loyal mating behaviors, such as the Emperor Penguins of Antarctica, who form monogamous pairs during the breeding season and jointly incubate and raise their chicks. During this process, they often engage in romantic dances and behaviors to strengthen their bond. Some birds even display romantic behavior when building their nests; for example, guinea hen decorates their nests with flowers and feathers, while black-bellied warblers use ferns and moss to create a cozy home. This article introduces the world's top ten lovebirds: the Great Hornbill, Sandpiper, Bald Eagle, Albatross, Love Parrot, Red-billed Leiothrix, Black-necked Swan, Crested Ibis, European Robin, and Mandarin Duck. The Great Hornbill is a well-known lovebird, remaining together for life once they fall in love. What love stories do the other birds have? Let's take a look.

1. Great Hornbill
The Great Hornbill is renowned for its monogamous relationships, being one of the few bird species known for its unwavering loyalty in love. Once they mate, they remain together for life. Their breeding season typically runs from March to June. During this period, the female is responsible for incubation, which takes approximately 31 days. Furthermore, Great Hornbills are altricial. Throughout the incubation and chick-rearing process, the male provides all the food. To ensure both the female and chicks have sufficient food, the male must repeatedly fly out to forage. Consequently, by the end of the breeding season, the female and chicks are plump, while the male becomes extremely thin due to exhaustion.

2. Sandpiper
The kiwi is a unique species found only in New Zealand, and is the country's national bird and symbol. Also known as the kiwi or common rooster, it is about the size of a rooster and, like the ostrich, cannot fly. Kiwis are known among birds for their standard monogamous relationship and can live up to 30 years. Barring unforeseen circumstances, they will remain together until the end of their lives. If one partner dies, the remaining one will live a solitary life.

3. Bald Eagle
Bald eagles are monogamous birds, also known as American eagles, and are one of the national birds of the United States. They have a very strong emotional bond, remaining with only one mate for life. If one mate dies, the other usually follows quickly. Bald eagles have pale yellow eyes, beaks, and feet, and their plumage varies in color across different parts of their bodies. Their head, neck, and tail feathers are white, while the rest of their bodies are dark brown, making them very beautiful and magnificent. During the breeding season, bald eagles often gather in flocks in areas with abundant food, choosing to nest on cliffs or in the tops of tall trees.

4. Albatross
Albatrosses are among the most devoted lovers in the world. Despite spending over 90% of their time at sea, they remember their home's location perfectly, returning precisely there every year at the end of October. Unmarried albatrosses begin searching for mates, while married albatrosses patiently await their mate's return. Once they choose a partner, they remain together for life. Even more remarkably, even after years of separation, albatrosses can remember their partner's voice and appearance, easily identifying their mate among a vast flock.

5. Couple parrots
Lovebirds, also known as pair lovebirds, refer to all species within the genus *Pseudorasbora*. These birds are highly prolific breeders, capable of breeding year-round, but their main breeding seasons are between February/March and April/October. During each breeding season, only the female incubates the eggs, which typically consist of 4-6 eggs. They can breed 2-4 broods per year. Lovebirds are named for their affectionate nature. They are always inseparable from their partners, often remaining together for life.

6. Red-billed Leiothrix
The Red-billed Leiothrix is a bird with vibrant plumage, a graceful form, a lively nature, and a melodious, moon-like call. Their average lifespan is about 10 years. If you've ever kept a Red-billed Leiothrix, you'll know that when you place a female and a male in separate cages and feed them close together, the male will sing softly to the female, as if whispering sweet nothings. When you separate them, the male will sing loudly and incessantly, seemingly expressing his longing for the female. It is because of this behavior that they are called the Red-billed Leiothrix.

7. Black-necked Swan
Black-necked swans are among the most monogamous animals in the world, adhering to a strict monogamous system and not seeking mates casually. Once a pair is formed, they are extremely affectionate, always together, and remain companions for life. During foraging, resting, playing in the water, and migration, they never abandon each other, always looking out for one another. If one dies, the other will grieve deeply, preferring solitude to seeking another mate. Furthermore, black-necked swans are very family-oriented, with both male and female sharing the responsibility of raising their offspring. Unlike other birds, black-necked swans carry their cygnets on their backs, showing meticulous care and affection for their young.

8. Crested Ibis
The crested ibis is a very precious bird, known as the "Jewel of the Orient," and is also famous for its lovebirds. They adhere to a monogamous system and emphasize the concept of lifelong mates; if one partner dies, the other will never mate again. Formerly known as the red ibis or crested heron, the crested ibis is a species endemic to East Asia. In the past, they were widely distributed in eastern China, Japan, Russia, and Korea, but their population declined sharply due to environmental degradation and other factors. Currently, all crested ibises in the world are descendants of a single wild population of only seven individuals from the southern foothills of the Qinling Mountains in Yangxian County, Shaanxi Province, China.

9. European Robin
The European Robin, also known as the robin, is a very romantic and loving bird that expresses its affections through singing, dancing, and protecting its nest. During the breeding season, male robins attract females with songs and dances, forming stable pairs and living together. They work together to ensure the nest is comfortable, dry, and safe, and to provide sufficient food and protection for the hatchlings. In this process, they depend on and support each other.

10. Mandarin Ducks
The Mandarin Duck is a medium-sized duck belonging to the order Anseriformes, measuring approximately 38-45 cm in length and weighing about 0.5 kg. They are sexually dimorphic birds; the male has a red bill, orange-yellow legs, and brightly colored plumage, a beautiful crest on its head, a broad white eyebrow stripe behind its eye, and a pair of chestnut-yellow fan-shaped erect feathers on its wings. The female has a black bill, orange-yellow legs, a grayish-brown head and back, and white around her eyes, along with a fine white eyebrow stripe, making her very striking and unique. Mandarin Ducks are famous ornamental birds in China, and because they are usually seen in pairs, they are considered a symbol of love and loyalty.
