Join me in discovering the allure of the Apo Myna and the intricate ecosystem it calls home.
Habitat and Distribution of Apo Myna
The Apo Myna (Basilornis mirandus) is endemic to the Philippines and is primarily found in the montane forests of Mindanao Island.
Here’s a detailed look at its habitat and distribution:
Habitat
The Apo Myna inhabits subtropical or tropical moist montane forests, particularly in high-altitude areas. These forests are characterized by dense vegetation, including tall trees and thick undergrowth, providing ample cover and bird nesting sites.
The Apo Myna is often found in the canopy or mid-story of these forests, foraging for food and engaging in social interactions with other individuals.
Distribution
The distribution of the Apo Myna is limited to specific regions within the Philippines, particularly in the montane forests of Mindanao Island. Within Mindanao, it is primarily associated with two key mountain ranges:
- Mount Kitanglad: Located in the province of Bukidnon, Mount Kitanglad is one of the highest peaks in the Philippines and is home to a significant population of Apo Mynas.
The bird thrives in the montane forests of this mountain range, where it can be found at elevations ranging from 1,100 to 2,600 meters above sea level. - Mount Apo: Mount Apo, located in the province of Davao del Sur, is the highest mountain in the Philippines and another critical habitat for the Apo Myna.
Like Mount Kitanglad, Mount Apo’s montane forests provide a suitable bird habitat, supporting breeding populations at higher elevations.

Furthermore, its feet are adorned with bright yellow hues, adding another splash of color to its appearance.
Beak
Equipped with a strong, slightly curved beak, the Apo Myna is well-suited for its omnivorous diet. The beak’s robust structure enables the bird to efficiently forage for various food items, including insects, fruits, and seeds.
Vocalizations
While not strictly a physical characteristic, the Apo Myna’s vocal repertoire is noteworthy. It emits various calls, including whistles, squawks, and warbling notes.
Moreover, the bird can mimic sounds from its environment, further enriching its auditory communication.
Yellow Feet
Another striking feature of the Apo Myna is its bright yellow feet, which add color to its overall appearance. These colorful feet are visible when the bird is perched or in flight.
Behavior and Diet of Apo Myna
The behavior and diet of the Apo Myna (Basilornis mirandus) are fascinating aspects of its ecology. Here’s a closer look at these aspects:
Behavior
The behavior of the Apo Myna encompasses a range of fascinating activities that reflect its adaptation to life in the montane forests of the Philippines.
Here are some key aspects of its behavior:
Social Behavior
Apo Mynas are social birds congregating in small groups or pairs, especially during breeding season. They engage in various social activities, such as preening each other’s feathers, which helps strengthen social bonds within the group.
Their vocalizations are crucial in communication within the flock, conveying information about food sources, potential threats, and territorial boundaries.
Vocalizations
Apo Mynas are known for their diverse vocalizations, including whistles, squawks, and warbling notes. They also can mimic sounds from their environment, including other bird calls and human noises.
Vocal communication serves multiple purposes for Apo Mynas, including mate attraction, territory defense, and coordination during foraging.
Foraging Behavior
Apo Mynas employ various techniques when foraging for food, such as probing leaves with their sharp beaks and flipping over bark sections to uncover hidden insects.
They are primarily insectivorous, with beetles and caterpillars comprising a significant portion of their diet.
However, they also consume fruits and seeds opportunistically, mainly when insect prey is scarce.
Diet
The diet of the Apo Myna is primarily insectivorous, but it also includes fruits and seeds opportunistically. Here’s a closer look at its dietary habits:
Insectivorous Diet
Insects form the primary component of the Apo Myna’s diet, with a preference for beetles and caterpillars.
The birds actively seek These protein-rich prey items, which use their keen eyesight and agile beaks to capture them from foliage, tree bark, and other surfaces within their forest habitat.
Frugivorous Diet
While insects make up the bulk of their diet, Apo Mynas also consume fruits and seeds when available. They may supplement their insectivorous diet with fruits such as berries, figs, and seeds from various plant species.
This dietary flexibility allows the birds to adapt to changing food availability throughout the year.
Threats and Conservation Efforts of Apo Myna
The Apo Myna (Basilornis mirandus) faces several threats to its survival, primarily due to human activities and habitat degradation. However, various conservation efforts are underway to protect this species and mitigate these threats.
