Ever find yourself walking through Florida and catch a glimpse of a tiny, curious monkey darting through the trees? Yep, squirrel monkeys have made their way to Florida, but they’re not from here originally—they just hang on in a few scattered groups after escaping or being released.
Curious about why these monkeys show up and where to find them? Let’s look at their backstory, where they are now, and how they fit in with Florida’s other wild monkeys.
You’ll find out which spots have sightings, why some groups didn’t last, and what you should do if you bump into one.
Squirrel Monkeys in Florida: History and Current Status
Let’s talk about how squirrel monkeys live where they come from, how small groups ended up in Florida, and why some populations disappeared.
We’ll also touch on what makes Saimiri monkeys unique and how that affects their chances here.
Origins and Native Habitat
Squirrel monkeys (genus Saimiri) come from the tropical forests of Central and South America. Most wild Saimiri, like Saimiri sciureus, stick to the Amazon and nearby regions.
They love tall forests with open areas underneath, so they can leap and zip around the branches.
Their diet is pretty varied—fruit, insects, tiny vertebrates, and other small critters. That makes them great at spreading seeds back home.
They’re small—about 25–35 cm long—and they don’t like being alone. You’ll usually find them in social groups that range from a few dozen to more than a hundred.
How Squirrel Monkeys Arrived in Florida
People brought squirrel monkeys to Florida, mostly through escapes, releases, and the pet trade. The mid-20th century saw several introductions when private owners, roadside attractions, or animal facilities kept monkeys.
Sometimes the owners let them go on purpose; other times, monkeys just got loose.
The illegal pet trade and swapping monkeys around helped them spread even more. There’s a well-known group that started on the Bartlett Estate in Fort Lauderdale in the 1970s (UF/IFAS review of nonnative monkeys).
Cold winters and people trapping them usually knocked their numbers down after they showed up.
Established and Extinct Populations
Florida’s seen at least five different introductions of squirrel monkeys, but only a couple really stuck around. One group began with just two pairs on a 35-acre estate in Fort Lauderdale and grew to dozens by 1988.
That group shrank over the years, and by 2021, only one monkey was left. Cold snaps and trappers probably did most of the damage.
Other groups popped up at Silver Springs, Masterpiece Gardens near Lake Wales, the Gordon River in Naples, and even after a campus release in 1970. Most of those groups vanished between the 1970s and 2010s.
Harsh winters, bigger monkeys taking over, people catching them for pets or research, and just not having enough monkeys to keep the gene pool healthy all played a part.

Unique Traits and Behavior of Saimiri
Squirrel monkeys are active during the day and extremely social. You’ll spot them foraging in the trees, usually in tight, noisy groups.
They eat fruit and lots of protein-rich prey like insects, which helps them survive in different spots and spread seeds for fruit trees.
Saimiri have quick metabolisms and thin fur, so cold Florida winters hit them hard. That’s a big reason most introductions didn’t work out.
These monkeys grab people’s attention—they’re small, bold, and not shy about approaching humans. That makes them targets for the illegal pet trade and people trying to feed them.
Their need for company means a single survivor isn’t likely to start a new wild group unless more monkeys get introduced.
Overview of Wild Monkeys in Florida
Florida actually has several types of non-native monkeys living out in the wild. Some have been around so long, researchers keep tabs on them because they can mess with native plants, animals, or even people.
Rhesus Macaque and Vervet Monkey Populations
Rhesus macaques mostly hang out around Silver Springs and the Ocklawaha River. People first let them loose in the 1930s, and since they’re strong swimmers, they spread into nearby forests.
These macaques eat everything from plants and bugs to eggs and small animals. Trapping has knocked their numbers down before, but they still stick around and sometimes damage habitats like mangroves or prey on ground-nesting birds.
Vervet monkeys live around Dania Beach and nearby spots. They probably showed up in the 1940s from an import facility.
Vervets eat fruit, crops, and small animals. Their groups are smaller and don’t shift as much as rhesus macaque groups.
People feed them a lot, which makes the monkeys less wary and more likely to wander into yards or public places.
Other Non-Native Species in Florida
Florida’s got plenty of other non-native animals besides monkeys. You’ve probably heard about Burmese pythons in the Everglades—they eat native birds and mammals and really hurt the local wildlife.
Lionfish live off Florida’s coasts and chow down on reef fish, upsetting the balance in those communities. Iguanas are everywhere in urban and suburban neighborhoods; they eat plants and dig burrows, messing up lawns and even infrastructure.
All these invasives have something in common with the monkeys: people brought them here, they spread in Florida’s warm climate, and they can shake up local ecosystems.
Some, like Burmese pythons and lionfish, get targeted by removal programs because they cause so much trouble. Others, like certain monkey groups, get managed more carefully due to legal rules or safety concerns.
Regulation and Management by the Florida Fish and Wildlife Conservation Commission
The Florida Fish and Wildlife Conservation Commission (FWC) sets the rules for owning, moving, or removing non-native animals, like monkeys. If you want to capture or keep primates, you have to follow FWC permits and local ordinances.
FWC works with researchers and trappers to keep an eye on animal populations. They’ll step in and remove animals that threaten public safety or native species.
The agency also tries to reach people directly—don’t feed wild animals, and if you spot something unusual, report it. For species that cause more trouble, like pythons or lionfish, FWC actually supports removal programs and even public hunts.
When it comes to monkeys, FWC tries to find a balance between animal welfare, public safety, and the health of the ecosystem. If you spot a monkey acting aggressively or in distress, let FWC know so they can send professionals to handle the situation.
