The Philippine eagle, also known as the monkey-eating eagle, is one of the largest and most powerful birds of prey in the world. These majestic raptors are endemic to the Philippine archipelago and are known for their impressive nesting habits.
Nesting Habitat of Philippine Eagles
Philippine eagles primarily nest in tall trees with open crowns, often on emergent dipterocarps. These trees provide the eagles with a stable and secure platform to build their massive nests. The nests are typically constructed high in the main fork of the tree, often on a platform of ferns and orchids.
The nest itself can be quite impressive, measuring nearly 3 meters across and about 1.5 meters deep. This large size is necessary to accommodate the eagle’s sizeable wingspan and to provide a safe and comfortable environment for the eaglet.
Nest-Building and Courtship

Nest-building is an important part of the Philippine eagle’s courtship ritual. The male and female work together to construct the nest, with the female taking the lead in the actual construction process. This collaborative effort helps to strengthen the pair’s bond and prepare them for the challenges of raising a chick.
During the nest-building and courtship phase, the eagles remain near their nest, vigilantly guarding their territory and ensuring the safety of their future offspring.
Egg-Laying and Incubation
The female Philippine eagle typically lays a single egg, although occasionally two have been reported. The egg is incubated for 58 to 68 days, with the female doing the majority of the incubating during the day and the male taking over at night.
Both parents play a crucial role in the incubation process, ensuring that the egg is kept at the optimal temperature and humidity levels. This dedication and teamwork are essential for the successful hatching of the eaglet.
Feeding and Parental Care
Once the eaglet hatches, both parents work together to provide food and care for their offspring. The newly hatched eaglet is dependent on its parents for sustenance and protection, and the parents will continue to feed and care for the eaglet for a total of 20 months.
During this time, the parents will bring a variety of prey to the nest, including small mammals, birds, and reptiles. The eaglet will gradually learn to hunt and fend for itself, eventually becoming independent and ready to establish its own territory.
Threats to Philippine Eagles
The Philippine eagle is a critically endangered species, with a population estimated to be between 180 and 500 mature individuals. The primary threat to the species is habitat loss due to deforestation, logging, and the expansion of agriculture.
Mining, pollution, exposure to pesticides that affect breeding, and poaching are also major threats to the Philippine eagle. The species is protected under Philippine law, with killing a Philippine eagle punishable by up to 12 years in prison and heavy fines.
Conclusion
The Philippine eagle is a remarkable and awe-inspiring bird of prey, known for its impressive nesting habits and dedicated parental care. Despite the many threats facing this species, conservation efforts are underway to protect and preserve the Philippine eagle for future generations.
By understanding the unique nesting requirements and behaviors of the Philippine eagle, we can better appreciate the importance of preserving the remaining old-growth forests and habitats that these majestic birds call home.
