15 King Bird-of-Paradise Facts
The King Bird-of-Paradise (Cicinnurus regius) is one of the most extraordinary birds in the world.
Found in the rainforests of New Guinea and surrounding islands, this tiny yet brilliantly colored bird has captivated birdwatchers and scientists alike.
With its vibrant plumage, elaborate courtship displays, and unique ecological role, the King Bird-of-Paradise is truly a marvel of nature.
Here are 15 fascinating facts about this stunning bird.
1. A Bird Draped in Royal Colors
The male King Bird-of-Paradise is a visual masterpiece, covered in bright crimson feathers from head to tail. Its iridescent green breast shield, fan-like shoulder plumes, and emerald green spiraled tail discs make it one of the most striking birds on the planet. Meanwhile, the females are more subdued in color, featuring brownish plumage with barred underparts to help them blend into the dense rainforest.
2. Tiny but Mighty
Despite its majestic appearance, the King Bird-of-Paradise is one of the smallest birds in its family. Males measure around 16 cm in length, but with their long tail feathers included, they can reach up to 31 cm. Interestingly, females tend to be slightly larger, averaging 19 cm in length.
3. Native to New Guinea’s Rainforests
This dazzling bird only inhabits the lowland rainforests of New Guinea, including both Papua New Guinea and Indonesian Papua. It can also be found on nearby islands like Aru, Salawati, Misool, and Yapen. The species thrives in both primary and secondary forests, frequently visiting forest edges and clearings.
4. A Fruity Diet with a Crunch
The King Bird-of-Paradise is primarily frugivorous, meaning it feeds mostly on fruits and berries. However, it also supplements its diet with small insects and arthropods, making it an omnivorous feeder. These birds play a crucial role in their ecosystem by dispersing seeds, which helps maintain rainforest biodiversity.
5. Nature’s Aerial Acrobat
When it comes to attracting a mate, male King Birds-of-Paradise put on a breathtaking show. Their courtship dance includes rapid tail swings, puffing out their white abdominal feathers to resemble a fluffy cotton ball, and executing pendulum-like movements. They often perform their displays from high perches in the canopy, creating a mesmerizing sight.
6. A Fatherless Upbringing
Unlike many bird species, the male King Bird-of-Paradise does not help with raising chicks. They follow a polygynous mating system, meaning that males mate with multiple females but do not participate in nesting or chick-rearing. Females build small cup-shaped nests inside tree cavities, incubate the eggs for about 17 days, and care for the chicks until they fledge around 14 days after hatching.
7. Conservation Status: A Bird Holding Strong
Despite their popularity and demand for their beautiful plumage, King Birds-of-Paradise are not currently endangered. Thanks to their wide distribution and adaptability, they are classified as Least Concern on the IUCN Red List. However, habitat destruction remains a potential threat to their future.
8. A Symbol of Cultural Heritage
For many indigenous communities in New Guinea, the King Bird-of-Paradise is more than just a beautiful bird—it is a symbol of status and tradition. The bird’s striking feathers are often used in ceremonial attire and rituals, demonstrating its deep cultural significance.
9. Named by a Scientific Pioneer
The King Bird-of-Paradise was first described by Carl Linnaeus in 1758, making it one of the earliest recorded birds-of-paradise. It is the only member of the genus Cicinnurus, a name derived from Greek, meaning “curled lock of hair”—a reference to its distinctive spiral tail feathers.
10. A Bird with a Unique Voice
These birds are not just beautiful; they are also very vocal! The males produce a series of mechanical-sounding notes that they repeat persistently, especially during the breeding season. These calls help attract females and establish territory in the dense rainforest.
11. Masters of Adaptation
Although they prefer lowland rainforests, King Birds-of-Paradise have also been found in gallery forests and secondary growth areas. Their ability to thrive in forest edges and disturbed habitats has helped them maintain stable populations despite deforestation.
12. Solitary and Secretive
Outside of the breeding season, these birds are rarely seen. They tend to be solitary, avoiding large groups and spending most of their time hidden in the dense foliage. Their elusive nature makes them one of the more challenging birds-of-paradise to observe in the wild.
13. Essential to the Ecosystem
King Birds-of-Paradise do more than just look pretty—they help maintain rainforest balance. By eating fruits and insects, they contribute to seed dispersal and control insect populations, playing a crucial role in forest regeneration and pest control.
14. First Successful Captive Breeding
The first known captive breeding of the King Bird-of-Paradise was achieved in 1958 by Swedish ornithologist Sten Bergman. This milestone provided valuable insight into the species’ breeding habits and helped inform conservation efforts.
15. Bright Blue Feet for Extra Charm
As if their crimson feathers, green chest shield, and spiraled tail discs weren’t enough, male King Birds-of-Paradise also have striking bright blue legs and feet. These vibrant colors help enhance their courtship displays, making them even more irresistible to potential mates.
