Malaysia’s tropical rainforests host an incredible array of wildlife, recognised as one of the worlds leading ‘biodiversity hotspots.’ Spending time trekking through the forests, you can see, hear, and sense the presence of this diversity all around you. The huge variety has led to some truly remarkable adaptations and quirks in evolution. Some of these little oddities have seen their owners pushed right to the brink of extinction. One bird species in particular has seen their numbers plummet in a very short amount of time, jumping from being ‘Near Threatened’ straight to ‘Critically Endangered’ in 2015 when the IUCN re-evaluated their conservation status. At this point in time, no one is sure how many of these majestic birds are even left in the wild. The Helmeted Hornbill (Rhinoplax vigil) is truly one of the most amazing birds across South-East Asia, but also one of the most endangered.
