You’d probably guess tigers hunt deer or wild boar, right? Turns out, in some parts of Thailand, GPS tracking shows certain tigers going after much smaller or unexpected animals—things like badgers and other little mammals.
When tigers switch up their prey, it often means their habitat’s shrinking and the big animals are disappearing. That’s a problem for tiger survival.
As you read on, you’ll spot which odd prey show up most and what GPS data and field teams have found about how tigers hunt. You’ll also get a sense of why tigers are making these changes and what conservationists try to do about it.
Strange Prey Choices for Thailand’s Tigers
Researchers keep finding that tigers in Thailand are hunting smaller or unexpected animals. They’re tracking this shift using GPS collars and camera traps.
Dietary Shift: Why Tigers Are Hunting Unusual Animals
Normally, you’d expect tigers to eat big deer or wild pigs. But in the Dong Phayayen-Khao Yai Forest Complex (DPKY-FC), some Indochinese tigers go after much smaller creatures.
Habitat loss, roads, and hunting by locals have cut down the numbers of large prey. When those animals disappear, tigers basically have to adapt or starve.
Panthera and other conservation groups started tracking tigers with GPS collars and cameras to watch this change. They’ve seen tigers eating animals that are easier to catch and more common near people.
This shift isn’t great for tigers. Smaller prey means less energy, which can hurt their health and how many cubs they have.
Tigers need big, calorie-rich meals to survive and keep their territory. When they chase smaller prey, they have to hunt more often and risk running into people.
Documented Unusual Prey in Dong Phayayen-Khao Yai
Researchers have spotted tigers eating a surprising range of animals. Camera traps and GPS data show kills like hog badger, muntjac deer (which are pretty small), and young wild pigs.
Some tigers even eat big reptiles—soft-shell turtles and water monitors—especially near rivers and wetlands.
These odd meals pop up more in places where sambar deer and adult wild pigs have disappeared. Field reports and GPS news stories back this up.
Tigers seem pretty flexible in what they’ll eat, but these animals don’t pack as many calories as the big prey tigers prefer.
Individual Tiger Case Studies: Chantra and Others
If you follow individual tigers with GPS collars, you’ll see some interesting stories. For example, one tigress spent a lot of time by rivers and wetlands, catching water monitors and soft-shell turtles.
Another male tiger often took muntjac and hog badger near the forest edge.
Camera traps at GPS collar locations help confirm these weird kills. These case studies show a pattern: tigers in more fragmented or hunted areas of DPKY-FC end up eating smaller animals.
These stories help conservationists decide where to boost prey or step up anti-poaching work.
Causes Behind Unusual Prey Selection
Three main things push tigers to hunt odd animals: their usual prey disappearing, land getting chopped up by roads and farms, and tiny, isolated tiger groups changing how they act.
Prey Scarcity and Impact on Tiger Health
When sambar deer, banteng, gaur, and wild pig numbers drop, tigers get hungry fast. Surveys in Thailand’s Western Forest Complex show those big animals are what tigers mostly eat.
If poaching or habitat loss wipes out these prey, tigers turn to smaller or unusual animals just to get by.
Sometimes tigers even go after domestic animals or really odd wild prey if sambar and banteng are missing. That raises the chance of run-ins with people and getting caught in snares.
A conservation manager in Huai Kha Khaeng and Thap Lan has noticed tigers look thinner and have fewer cubs when prey is scarce.
Keeping prey numbers up helps tigers stay healthy and have babies. Supporting anti-poaching patrols, prey counts, and habitat protection makes a real difference.
Habitat Fragmentation and Human Pressure
Highways, farms, and new towns chop tiger territory into smaller and smaller pieces. Roads like Highway 304 and more farmland create “empty forests”—the trees are there, but the big animals are gone.
Fragmentation traps tigers in places like Khlong Lan National Park and parts of the Western Forest Complex, making hunting tough.
Tigers cross human areas more often when their space shrinks. That leads to more encounters with people and with poachers who target both tigers and their prey.
Wildlife crime often spikes near forest edges and in corridors, cutting off movement between protected areas like Huai Kha Khaeng and Thap Lan.
Restoring corridors and blocking new roads can help bring tiger populations back together. You can support fence-free corridors, fund underpasses, or push for more patrols in broken-up landscapes.
Genetic Diversity and Small Tiger Populations
Small, isolated tiger populations lose genetic diversity over time. Inbreeding often lowers disease resistance and can even change how tigers behave—which, honestly, might mess with their hunting choices.
Tigers stuck in certain parts of the Western Forest Complex rarely get to meet tigers from other regions. That isolation just makes things worse.
When genetic diversity drops, fewer cubs survive. Adults can end up weaker too, struggling to take down big prey like sambar or gaur.
Panthera Thailand and some other groups keep a close eye on tiger genetics. They use what they learn to plan moves or set up protected corridors, hoping to boost gene flow.
If people actively move tigers between protected blocks or make sure corridors stay open, genetic health improves. Supporting these efforts really helps tigers keep their natural prey instincts and gives them a better shot at survival.
