The crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque, is a highly intelligent and adaptable primate found throughout Southeast Asia. Despite the name, crabs are only a small part of their diet. They eat everything from fruit and seeds to small animals and, wherever they can find them, human leftovers. I photographed this one outside of a temple on the Malay Peninsula of Thailand. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/1000th of a second.

I was only in Thailand for five nights back in 2016, but had some pretty good sightings, especially while camping in Kaeng Kratchen National Park on the Malay Peninsula. A few Malayan porcupines would come sniffing around the camp ground every night trying to see what they could find.

I was only in Thailand for five days, but I had some great sightings, including this white-handed gibbon. I saw several of these guys, both the chocolate brown morph as well as cream-colored morphs like this one. Photographed in Kaeng Krachan National Park on the Malay Peninsula. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/320th of a second.

Baby stump-tailed macaques can look like infants and senior citizens at the same time. This little guy was hanging out with a few friends just outside of Kaeng Krachan National Park on the Malay Peninsula of Thailand. Nikon D810 with Nikkor 70-200mm lens (at 200mm), ISO 1600, f/4 at 1/800th of a second.

I photographed two species of langur on my short trip to Thailand back in 2016. This is the Robinson’s banded langur, otherwise known as the Robinson’s banded surili. At the time I took this photograph, it was still considered a sub-species of another type of langur but in 2019 genetic analysis determined it to be its own species. Always interesting to find out that what scientists thought was true of an animal when I took a photograph is no longer the case. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/125th of a second.

The lar gibbon, also known as the white-handed gibbon, is an endangered ape from Southeast Asia. They are endangered due to many factors, the most pervasive being the continued loss of their habitat. I photographed this one on the Malay Peninsula of Thailand. He was swinging from that tree while calling to his mate. Nikon D500 with Nikkor 200-400mm lens (at 330mm) ISO 800, f/4 at 1/1600th of a second.

I spent a few nights camping in Thailand’s Kaeng Krachan National Park. On one of those nights, a Malayan porcupine stopped by for a visit. This image gives a good look at those quills, which are actually hollow, hardened hairs made of keratin. Nikon D810 with Nikkor 70-200mm lens (at 155mm) ISO 500, f/9 at 1/250th of a second, two Nikon SB-900 flash units.

I went all the way to Thailand to photograph squirrels. Well, actually I was there to photograph all sorts of amazing creatures, but didn’t expect to get as excited about these giant black squirrels as I did. It’s tough to get a sense of scale from a picture like this but they are much larger than the grey and red squirrels we have here in the US. That two-tone coloring is also pretty cool. I only had a few sightings, including this one in Kaeng Krachan National Park. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 1600, f/4 at 1/320th of a second.

Tree monitors are big lizards. Very big. I’d say this guy was somewhere between four and five feet long. He/she clung to that tree, not moving but keeping an eye on us as we slowly drifted by in a boat. Photographed in Khlong Saeng in Thailand. Nikon D500 with Nikkor 200-400mm lens (at 350mm) ISO 800, f/4 at 1/400th of a second.

A baby stump-tailed macaque peers through the thick vegetation, near Kaeng Krachan National Park on the Malay Peninsula of Thailand. Nikon D810 with Nikkor 200-400mm lens (at 280mm) ISO 1600, f/5.6 at 1/250th of a second.
