Habitat and Distribution of the Chestnut-Breasted Malkoha

Habitat and Distribution of the Chestnut-Breasted Malkoha

The Chestnut-Breasted Malkoha (Phaenicophaeus curvirostris) is a remarkable bird endemic to Southeast Asia, encompassing regions of Thailand, Malaysia, Brunei, Indonesia, and Singapore.

Let’s delve into its habitat and distribution:

Geographical Range

The Chestnut-Breasted Malkoha is primarily found in the lush forests of Southeast Asia. Its distribution spans various regional countries, highlighting its adaptability to diverse environments.

Habitat Preference

These birds are predominantly forest dwellers, preferring primary and secondary forests characterized by dense vegetation.

However, they have also been observed in other habitats, including plantations and urban parks, demonstrating their ability to adapt to varying environments.

Behavioral Traits

The Chestnut-Breasted Malkoha exhibits secretive behavior, often hidden among its preferred habitats’ leafy canopies or tangled vegetation. Despite its broad distribution, this behavior and its preference for dense foliage make it challenging to observe.

Population Trends

While concrete data on population trends is limited, preliminary observations suggest a potential decline in numbers.

Habitat loss, mainly due to deforestation for palm oil plantations, poses a significant threat to the Chestnut-Breasted Malkoha population in some areas.

Conservation Implications

Understanding the distribution and habitat preferences of the Chestnut-Breasted Malkoha is crucial for conservation efforts to preserve its populations.

Conservation measures focusing on protecting and restoring its preferred forest habitats can play a vital role in ensuring the survival of this elusive bird species.

Physical Characteristics of the Chestnut-Breasted Malkoha

The Chestnut-breasted Malkoha (Phaenicophaeus curvirostris) is a captivating bird with distinct physical characteristics that make it easily recognizable in its habitat.

Let’s delve deeper into these fascinating features:


Ranging from 42-46 cm in length, the Chestnut-breasted Malkoha is one of the larger species of cuckoos, exhibiting a robust and sizable build compared to many other avian species.


Typically weighing between 77-92 grams, these birds possess a substantial weight that complements their size, contributing to their overall presence within their ecosystem.


The Chestnut-breasted Malkoha displays a striking contrast in its coloration. While the upper body, including the wings and tail, is predominantly greenish-black, the breast and belly are adorned with enchanting chestnut-brown plumage, lending the bird its distinctive name.

Adding white-tipped long tail feathers, stretching up to two-thirds of their total length, further enhances the bird’s aesthetic appeal and visual allure.

Unique Facial Features

One of the most notable features of the Chestnut-breasted Malkoha is the illustrious blue skin patch surrounding each eye. This feature adds a touch of vibrancy to the bird’s appearance and contributes to its unique and eye-catching look.

Additionally, male and female Malkohas boast black bills, with males typically having slightly longer bills than females, although this distinction may be subtle.

Feet Structure

Adapted for life in arboreal environments, the Chestnut-breasted Malkoha possesses zygodactyl feet.

This foot structure, characterized by two toes facing forward and two backward, facilitates effortless navigation through tree branches, enabling the bird to move with agility and precision in its forest habitat.

Arboreal Lifestyle

The Chestnut-Breasted Malkoha is primarily arboreal, spending most of its time in the trees. This habitat preference provides a sense of security and ample foraging opportunities.

Diverse Diet

The Malkoha has a diverse diet, consuming a variety of prey, including insects, caterpillars, and small reptiles. It must demonstrate more dietary selectivity and willingness to consume any suitable prey that crosses its path.

  • Insects: Particularly fond of beetles and ants, these insects form a significant portion of the Malkoha’s diet.
  • Caterpillars: Considered a delightful find, the Malkoha also consumes caterpillars when available.
  • Small Reptiles: While less common, small reptiles such as lizards are relished as a rare treat by the Malkoha.

Foraging Technique

The Malkoha employs a patient hunting technique, often remaining still on a branch and waiting for unsuspecting prey to come within striking distance. Once prey is within reach, the Malkoha swiftly swoops down to capture its meal.

Social Interactions

Social interactions for the Chestnut-Breasted Malkoha primarily occur during mating season and when raising offspring. They typically engage with members of their species during these periods, building nests amongst dense vegetation for breeding purposes.

Elusive Nature

Despite its vibrant plumage, especially during mating season, the Chestnut-Breasted Malkoha is known for its elusive behavior.

By blending into the foliage, it effectively hides from predators and observers alike, making sightings of this bird species a special treat for birdwatchers.

Conservation Status of the Chestnut-Breasted Malkoha

Conservation Status of the Chestnut-Breasted Malkoha

The conservation status of the Chestnut-Breasted Malkoha (Phaenicophaeus curvirostris) is indeed a matter of concern, as indicated by its classification as “Near Threatened” by the International Union for Conservation of Nature (IUCN).

Let’s explore the factors contributing to its declining status and the conservation efforts underway:

Habitat Loss

The primary threat to the Chestnut-Breasted Malkoha is habitat loss, primarily driven by deforestation and urban expansion in Southeast Asia.

As forests are cleared for agriculture, logging, and infrastructure development, Malkoha’s preferred habitats of dense forests are being rapidly depleted, leaving them with limited suitable habitat.

Illegal Wildlife Trade

The stunning appearance and unique call of the Chestnut-Breasted Malkoha make it a target for illegal wildlife trade.

This includes the illegal pet trade, where individuals are captured from the wild and sold as exotic pets. Illegal hunting and trade further exacerbate population decline and threaten the species’ survival.

Conservation Efforts

Efforts are underway to conserve the Chestnut-Breasted Malkoha and its habitat. Several protected areas have been established across its range, aiming to safeguard essential habitats and provide safe spaces for breeding and nesting.

These protected areas play a crucial role in preserving biodiversity and mitigating the impacts of habitat loss.

Need for Urgency

While some conservation measures are in place, the pace of progress could be faster, and there is a need for more urgency in addressing the threats facing the Chestnut-Breasted Malkoha.

Increased efforts are required to combat habitat loss, mitigate the impacts of illegal wildlife trade, and raise awareness about the importance of conserving this species and its habitat.


The Chestnut-Breasted Malkoha offers a captivating glimpse into the intricate biodiversity of Southeast Asia. Its vibrant plumage, unique call, and elusive nature symbolize the region’s rich natural heritage.

While not currently threatened, habitat loss due to development and deforestation poses significant risks to its survival. Conservation efforts are paramount to safeguarding this species and its habitat for future generations.
