Birds of paradise are known for their beautiful and elaborate plumage. The males use their bright colors and unique feathers in courtship displays to attract females. But do these displays also catch the attention of another observer – ants? Let’s take a closer look at the relationship between birds of paradise and ants.
Do ants eat bird of paradise feathers and skin?
Ants are attracted to sources of protein, fat, and carbohydrates. Bird of paradise feathers and skin could provide ants with fatty acids and protein. Additionally, birds may have small parasites on their skin and feathers that ants could feed on.
A few observations suggest that ants are interested in eating birds of paradise:
- Ants have been observed swarming birds of paradise during courtship displays.
- Ants will readily feed on discarded feathers and dead birds.
- Species like Pheidole ants have powerful jaws and appetites for insects, dead animals, and seeds.
However, living birds of paradise likely have defenses to prevent ants from consuming them. Their feathers contain antimicrobials to reduce parasites and bacteria. Birds also preen themselves to distribute protective secretions. Overall, while ants may nibble, living birds prevent serious ant damage.
Do ants pose a threat to bird of paradise eggs and chicks?
Ants could threaten defenseless bird of paradise nests. Birds lay their eggs in nests built in trees and shrubs. The eggs and chicks are immobile and may attract opportunistic ants.
Certain ant species are known nest predators. For example, some ants in the genera Anoplolepis and Pheidologeton raid nests for eggs and chicks. Birds have some strategies for protecting their nests from ants:
- Aggressive defense – parent birds may physically attack ants near their nest.
- Abandoning ant-infested nests – birds may leave compromised nest locations.
- Chemical secretions – applying antimicrobial liquids to deter ants.
However, these defenses are not perfect. One study in Papua New Guinea found 20% of bird of paradise nests were raided by ants. So ants likely represent a consistent, opportunistic threat to reproductive success.
Do bird of paradise displays attract ants?
The elaborate mating displays of male birds of paradise serve to attract receptive females. But the commotion, bright colors, and exposed skin may also catch the attention of foraging ants.
Certain observations indicate ants are drawn to courtship activity:
- Male displays often occur at fixed lek sites for many years, allowing ants to consistently locate displays.
- Groups of ants have been seen climbing display perches and approaching males.
- Males may pause displays to peck at ants, suggesting irritation.
However, this attraction may be accidental rather than purposeful. Ants likely congregate at leks simply because they serve as regular sources of dead insects, feathers, and fallen fruit. The birds themselves may represent only a passing food curiosity.
Do ants help keep leks clean for birds of paradise?
An intriguing possibility is that ants help maintain sanitary lek conditions. As mentioned, leks are display sites reused for many mating seasons. Buildup of rotting fruit, dead insects, and feathers may occur at active leks.
Researchers propose that ants may provide a beneficial cleaning service for leks. Ants are adept scavengers and would readily feed on leftover debris. This could reduce parasite loads and prevent contaminated conditions that might sicken birds.
However, this idea remains speculative. More research is needed to determine if birds benefit from potential ant sanitation or simply tolerate ant scavenging.

Conclusion
Ants are likely attracted to birds of paradise for potential food sources, including feathers, skin particles, dead insects, and fruit debris. Their presence at display leks may be an accidental consequence rather than intentional targeting of the birds. Ants pose some threats, especially nest raiding, but may also provide cleaning services that reduce disease transmission. More research is needed to better understand the intricacies of the ant-bird relationship.
In summary, ants are probably not specifically targeting birds of paradise as prey. But their opportunistic scavenging brings complex tradeoffs for the beautiful birds as they pursue their elaborate mating rituals.
