Nestled in the far corners of Borneo, the Sungai Kapur Virgin Jungle Reserve (VJR) emerges as a captivating haven for nature and wildlife enthusiasts, beckoning with its rich biodiversity and pristine landscapes. Among its many treasures is the reserves avian wonders that grace the rainforests, making it a paradise for bird enthusiasts and nature lovers.

Let’s explore the Top Birds that can be found in the Sungai Kapur Virgin Jungle Reserve (VJR).

Bornean Ground Cuckoo

The Bornean Ground Cuckoo (Carpococcyx radiceus) is an elusive avian wonder, shrouded in mystery, adds a touch of elegance to the diverse tapestry of Sungai Kapur’s fauna. It is currently classified as vulnerable by IUCN, and just like the other birds on this list, its species is threatened by habitat loss.

This ground-dwelling species is approximately 40cm in length and its plumage is predominantly brown, marked with intricate patterns, providing excellent camouflage amidst the forest floor. The distinctiveness of the Bornean Ground Cuckoo extends to its slender, downward-curving bill, suited for foraging on the forest floor for insects, small reptiles, and fallen fruits.

This species thrives in the understory, where its muted plumage aids in seamlessly blending with the forest foliage. Renowned for its terrestrial habits, the Bornean Ground Cuckoo spends much of its time foraging on the ground, utilising its keen sense of sight to locate prey. Despite its terrestrial tendencies, this species is an adept flier, with powerful wings enabling it to navigate the forest canopy when needed.

Bornean Crested Fireback

The Sungai Kapur VJR provides an ideal haven for the Bornean Crested Fireback or scientifically known as Lophura ignita and is currently classified as vulnerable by IUCN. The reserve offers a diverse range of habitats that cater to their specific needs.

The male Bornean Crested Fireback exhibit a length of up to 70cm, characterised by a dark crest reminiscent of a peacock, bluish-black plumage, a reddish-brown rump, black outer tail feathers, a red iris, and exposed blue facial skin. In contrast, the females present as brown birds featuring a short crest, blue facial skin, and black-and-white spots beneath.

These birds are often found in primary and secondary forests, thriving in areas with dense vegetation. While they predominantly forage on the forest floor for insects, seeds, and small vertebrates, the Crested Fireback’s unique adaptation lies in their ability to take refuge in the trees when threatened.

Witness their courtship displays during the mating season, where males showcase their vibrant plumage and engage in intricate dances to attract potential mates. Understanding the nuances of their habitat and behaviour adds depth to the birdwatching experience within the Sungai Kapur VJR.

Rhinoceros Hornbill

The Rhinoceros Hornbill (Buceros rhinoceros) reigns as a majestic symbol of the skies. Recognised for its remarkable size, distinctive casque, and vibrant plumage, this avian monarch holds a special place in both the cultural and ecological landscapes of the region.

Certain Dayak communities, particularly those belonging to the Iban groups, regard it as the paramount earthly bird or the ultimate terrestrial avian entity. They employ its figurine as means of extending a welcome to Sengalang Burong, the deity associated with augural birds, during various festivities and celebrations.

The males reach up to 90cm in length, making it one of the largest hornbill species. Its defining feature is the impressive casque atop its bill, resembling the horn of a rhinoceros, hence the name. Cloaked in black plumage, the male’s casque is a striking red-orange, while the female exhibits a smaller casque. They can also be distinguished based on their eyes, as the eyes of the male are red with black rims, and the females have white eyes with red rims.

Besides the Rhinoceros Hornbill, there are 7 other hornbill species that can be found within the Sungai Kapur VJR and they are the Black Hornbill, Wreathed Hornbill, Oriental Pied Hornbill, White-Crowned Hornbill, Bushy-Crested Hornbill, Wrinkled Hornbill and Helmeted Hornbill.

Sabah Partridge

The Sabah Partridge (Tropicoperdix graydoni), as its name suggest, is endemic to Sabah, Malaysian, Borneo and is considered by some to be a sub-species of the Chestnut-necklaced Partridge. Adorned with intricate patterns, the Sabah Partridge thrives in the tropical lowland rainforests. It is an uncommon species experiencing a decline across its habitat and is classified as near threatened by IUCN.

Cloaked in brown with buff scaling, it exhibits a rusty bib, a stippled black-and-white head pattern, and a pale throat. Typically foraging in small flocks on the forest floor, it stands out for being located at lower altitudes compared to other partridges in its range. Distinguished by a pale ear patch and the absence of rufous on the head, this bird showcases unique characteristics within its habitat.

Blue-Headed Pitta

Thriving in the heart of tropical rainforests, this pitta species is known for its elusive nature, often darting through the underbrush with agility. The Blue-Headed Pitta prefers the dense and diverse environments of lowland and montane forests.

The male’s vibrant electric-blue crown captivates even in the dimness of the forest floor, accompanied by dark blue underparts, a white throat, and a cinnamon-brown back. The female, on the other hand, features a warm cinnamon head and lighter brown underparts. Both genders display dark wings adorned with a distinctive white streak.

The Blue Headed Pitta is often found foraging on the forest floor, feeding on insects, small invertebrates, and fruits. During the breeding season, the air is filled with melodious calls, contributing to the rich symphony of the rainforest.

Storm Stork

The Storm Stork is a visual spectacle, adorned with contrasting black and white plumage. Its long neck and legs contribute to its stately presence, while its powerful wings enable it to navigate across great distances. One of the distinguishing features of the Storm Stork is its vibrant orange facial skin and beak, adding a burst of color to its monochromatic palette. With a wingspan reaching over six feet, this large bird is a testament to the grace and grandeur of nature.

Despite its majestic presence, the Storm Stork faces conservation challenges. Habitat loss due to deforestation, degradation of wetlands, and disturbance during its migratory routes pose threats to its survival. Recognizing the importance of preserving the ecosystems it depends on is crucial for ensuring the continued existence of this magnificent bird.

Great Argus Pheasant

The Great Argus, particularly the subspecies Argusianus argus grayi found in Borneo, is renowned for its extraordinary courtship display, considered one of the most remarkable in the animal kingdom. The male Great Argus has striking long feathers and tail plumes that give it a majestic, train-like appearance when at rest. Its head is blue, contrasting with the more warmly colored female, which lacks the elaborate plumes.

These birds inhabit lowland to foothill forests with sparse undergrowth and mature trees, where the male’s distinctive courtship call “kow-WOW” resonates loudly, despite its elusive nature. Named after Argus Panoptes, the mythical Greek giant with many eyes, the male Great Argus displays numerous ‘eyes’ (ocelli) on its tail feathers.

The diet of the Great Argus consists mainly of fruits, supplemented with insects scavenged from the forest floor. During the breeding season, the male performs an intricate dance to attract females. This involves spreading its tail feathers and dancing around a cleared patch of forest floor, which serves as its personal display ground. Mature males maintain these areas meticulously, keeping them free of leaves.
