An extraordinary birdwatching experience

Birds of Belum Temenggor

The area of Belum Temenggor has been recognized by Birdlife International as an “Important Bird Area” (IBA: MY07 – Belum-Temengor). Although, the rainforest has two parts because of a road splitting it. Therefore, the North is Belum and the South is Temenggor. In reality, it’s one single ecosystem, with both areas having similar habitats and bird populations.

There are 316 known bird species. Some are part of a restriction to the Sundaic lowland and montane forests. So far, they are recorded in Belum Temenggor rainforest. Therefore, this includes eight species listed as “vulnerable”: the Mountain Peacock Pheasant (Polyplectron inopinatum), the Wallace’s Hawk Eagle (Spizaetus nanus), the Masked Finfoot (Heliopais personata), the Large Green Pigeon (Treron capellei), the Short-toed Coucal (Centropus rectunguis), the Bluebanded Kingfisher (Alcedo euryzona), the Plain-pouched Hornbill (Aceros subruficollis) and the Straw-headed Bulbul (Pycnonotus zeylanicus). In addition, 56 other species are considered as “Near threatened”. The area is of outstanding importance for threatened Sundaic forest birds. There is a high avifaunal diversity and a large number of endangered species.

Hornbills Shangri-La

The importance of Belum Temenggor, however, lies in the fact that its forests are home to large numbers of hornbills. It’s the only site on Earth where you can see all of the ten known species of Malaysian hornbills : Plain-pouched HornbillWhite-crowned HornbillBushy-crested HornbillWrinkled HornbillWreathed HornbillBlack HornbillOriental Pied Hornbill, Rhinoceros Hornbill,  Great Hornbill and Helmeted Hornbill.

Other Bird Species

Dead trees can host specimens of Blyth’s Hawk Eagle (Spizaetus alboniger) or the smaller Black-thighed Falconet (Microhierax fringillarius). Other relatively common sightings in Belum Temenggor include the Blue-rumped Parrot (Psittinus cyanurus) and the Blue-crowned Hanging Parrot (Loriculus galgulus). Fruiting trees attract – besides hornbills – other frugivores such as green pigeons, barbets, leafbirds and bulbuls. Five species of barbet have been recorded, including the Red-crowned Barbet (Megalaima rafflesii) and the Redthroated Barbet (M. mystacophanos).

There is a variety of Bulbuls with 20 of the 26 Malaysian species. The rare Straw-headed Bulbul can sometimes vocalize and the sound is perceivable from the lakeside forest edge. The Sunda region is famous for babblers and Belum Temenggor rainforest is no exception, with at least 30 species present. Particularly, the ones to spot are Chestnut-winged (Stachyris erythroptera), Chestnut-rumped (S. maculata), Fluffybacked Tit (Macronous ptilosus), Sootycapped (Malacopteron affine), Short-tailed (Malacocincla malaccensis) and Brown Fulvetta (Alcippe brunneicauda) babblers. Other closed-forest species are easy to notice, like the Black-and-Yellow Broadbill (Eurylaimus ochromalus), the Green Broadbill (Calyptomena viridis) and the Dark-throated Oriole (Oriolus xanthonotus).

Temenggor Lake has few waterbirds as egrets and herons that are easy to spot. However, its fish population are food to several piscivores. The Lesser Fish Eagle (Ichthyophaga humilis) is widespread and in the rain season is joined by ospreys (Pandion haliaetus). In addition, there are several species of kingfisher to see all year long: as the Blue-eared Kingfisher and sometimes the Blue-banded Kingfisher.

Birdwatching activities

Birdwatching within the State Park usually is on small river boats. From the lake and its stream visitors can get excellent sightings and views of hornbills on their daily migrations to fruiting trees scattered throughout the forests. Moreover, the same cruising boat is productive for sighting larger species, kingfishers and edge foragers.

There are trails throughout various places surrounding the lake, giving access into the rainforest ecosystem. From here, visitors can expect to see endemic species as Trogons, Peacock-pheasants, Paradise-flycatchers and many others. Besides, camping in the rainforest would allow time and chances to observe smaller babblers, bulbuls, flycatchers, nectar feeders and leaf gleaners.

Check for bird-watching activities listed in Belum and Temenggor. For those who do not have the time or budget to bird in the Royal Belum State Park, it is possible to enjoy birding in the Temengor area. In either case, visitors will be in company of nature guides that will help to gather in best spots for photography and observation. As a recommandation, bring along binoculars or other optics, photographic lenses of 300mm and above. It’s always useful to have some guidebook at hand to recognize the species.

The best time to Visit Belum Temenggor to watch mass flights of hornbills and other species is from July to October. Thus, the birds congregate and move south into Temenggor. During these months, flocks fly out at dawn heading North to feed and return South in the evening, to undiscovered roost sites, deep in the Temenggor part of the rainforest.

Bird ethics and bird-watching rules

Visitors of Belum Temenggor must adhere and follow these good practices and guidelines while looking for and observing bird species in the protected areas :

  • Do not overplay recordings of bird sounds or try to avoid playback altogether (constant playback is counterproductive anyway).
  • Leave nests untouched. Do not break or move branches or leaves for a better view. Move yourself away from them.
  • Do not gather people around nests, distance yourself from the nests.
  • Do not point laser lights at birds (or any other type of light).
  • Minimize or avoid altogether the use of flash strobes in bird photography.
  • Do not point torch light into the eyes of night birds, or overuse artificial light.
  • Do not chase or go after ground birds for a better view. You could impact their foraging.
  • If you see visitors interfering with the wildlife or plants, inform the park authorities or the police.
  • Report any ringed/banded birds to Malaysian Nature Society.
