The Philippine eagle, also known as the monkey-eating eagle, is a critically endangered species that lays a single egg every two years. This slow reproductive rate is a significant factor in the conservation of this magnificent bird.
The Egg Laying Process
The female Philippine eagle undergoes a phase called “egg lethargy” before laying the egg. During this time, she appears sickly, does not eat for 8-10 days, and builds a nest. After the egg is laid, both the male and female parents take turns incubating it for about 58-68 days.
| Incubation Period | Duration |
|---|---|
| Female Incubation (Daytime) | Majority of the time |
| Male Incubation (Nighttime) | Remainder of the time |
Once the egg hatches, the eaglet stays in the nest for about 5.5 months, and the parents take care of it for about 17 months until it leaves their territory in search of its own habitat.
Factors Influencing Egg Laying

The Philippine eagle’s reproductive cycle is influenced by environmental factors such as the peak typhoon season in Luzon and the seasonal abundance of prey. These factors, along with habitat loss due to deforestation and shooting, contribute to the species’ critically endangered status.
Seasonal Factors
- Peak typhoon season in Luzon
- Seasonal abundance of prey
Threats to Reproduction
- Habitat loss due to deforestation
- Shooting
Conservation Efforts
The slow reproductive rate of the Philippine eagle, combined with the threats it faces, highlights the importance of protecting this magnificent bird and its habitat. Conservation efforts, such as habitat preservation, anti-poaching measures, and captive breeding programs, are crucial for the survival of the species.
The Philippine Eagle Foundation, a non-profit organization dedicated to the conservation of the Philippine eagle, plays a vital role in these efforts. They conduct research, educate the public, and work with the government to protect the species and its habitat.
Conclusion
The Philippine eagle’s reproductive cycle, with its single egg laid every two years, is a significant factor in its conservation. Understanding the factors that influence the eagle’s egg laying and the threats it faces is crucial for developing effective conservation strategies to ensure the survival of this iconic species.
