When people think about birdwatching in Panama, they usually look up. They search the treetops for toucans, scan the sky for parrots and macaws, watch hummingbirds around flowers and hope to spot a sloth moving slowly through the branches. But there is an entirely different world happening underneath the canopy.
Panama has a remarkable collection of birds that spend much of their time walking around on or close to the forest floor. They include tinamous, curassows, guans, wood quail, quail doves and ground doves. Some are large and spectacular, some are tiny and extremely secretive, and several have a distinctly chickenlike appearance. They are not all closely related, so “ground fowl” is more of a useful description than a scientific group. What they have in common is their connection with the vegetation, leaf litter and food resources of the forest floor.
Panama is an especially interesting place to encounter these birds because the country sits between North and South America and contains an extraordinary variety of habitats. The Smithsonian Tropical Research Institute notes that Panama's bird diversity is exceptional for a country of its size, partly because the isthmus connects two continents and provides important routes for birds moving between them.
The tinamous are some of Panama's strangest birds
If you are walking through a Panamanian rainforest and hear a beautiful whistle coming from somewhere nearby but cannot find the bird producing it, there is a good chance you have encountered a tinamou.
Tinamous are fascinating because they look somewhat like small, primitive chickens but belong to a very different evolutionary lineage. They spend much of their lives walking through vegetation and leaf litter rather than flying from tree to tree.
The Great Tinamou is one of the larger species found in Panama. It has a rounded body, short tail and understated brownish plumage that blends beautifully into the forest floor. It can be surprisingly difficult to see despite its relatively large size.
This is one of the great tricks of tropical forests. You might imagine that a large bird would be easy to spot, but size isn't everything. If the animal's colours closely match the leaves, shadows and branches around it, it can practically disappear.
The Little Tinamou takes hiding seriously
The Little Tinamou is smaller and even more difficult to observe. Rather than behaving like a typical bird that immediately takes flight when approached, it may simply run through thick vegetation.
That behaviour makes perfect sense when you consider its habitat. Dense tropical vegetation provides countless places to disappear, and flying can be energetically expensive and potentially dangerous.
For a birdwatcher, however, this creates a hilarious situation. You can be standing on a trail listening to a bird calling nearby, absolutely certain that it must be somewhere in the bushes, while the bird is apparently thinking, “If I don't move, perhaps this enormous ape will eventually leave.”
The result is that tinamous are often heard much more frequently than they are seen.
Their calls are incredibly important
The calls of tinamous are one of the most useful ways to detect them.
This is an important lesson for anyone exploring Panama's forests. Birdwatching is not simply about looking at trees. Once you become familiar with different calls, the forest becomes a completely different place.
A bird that was completely invisible five minutes earlier suddenly becomes obvious because you recognize its voice.
The Smithsonian's long history of bird research in Panama demonstrates just how important recording vocalizations and conducting systematic surveys are to understanding the country's birdlife. Researchers have spent decades walking trails, recording birds and documenting changes in their populations.
The Great Curassow is the heavyweight of the forest floor
If tinamous are subtle, the Great Curassow is anything but small.
This spectacular bird belongs to the family Cracidae, which also includes guans and chachalacas. Curassows are among the largest birds regularly encountered in Central American forests and can look almost like an oversized tropical chicken.
A male Great Curassow is particularly impressive, with a predominantly dark body, white belly and prominent crest. Females can look very different, with more complicated patterns and reddish or barred plumage.
Finding one walking along a jungle trail is a memorable experience.
Unlike many canopy birds, you don't have to crane your neck upward. You may simply look ahead and suddenly realize that there is a huge bird standing in the vegetation.
Curassows are more than beautiful birds
Large forest birds such as curassows have important ecological roles.
They consume fruits and other plant material, and their movements through the forest can contribute to seed dispersal. This makes large birds part of the process by which forests regenerate.
That becomes particularly important when you consider how interconnected tropical ecosystems are. A tree produces fruit, a bird eats the fruit, the bird moves somewhere else and eventually deposits the seed. The next generation of trees can therefore be connected to the movement of animals through the forest.
So a curassow walking through the jungle isn't simply looking for lunch.
It is potentially helping plant the next generation of rainforest.
Guans occupy a fascinating middle ground
Guans are another group of Panamanian birds that make the idea of “ground fowl” interesting because they aren't strictly ground birds.
They can spend significant amounts of time in trees but also move around on the forest floor. They belong to the same broad family as curassows and chachalacas and have strong legs and feet suited to moving through vegetation.
This flexibility is useful in a tropical forest because food isn't located in one place.
A guan might feed in a tree, move through branches and later descend to the ground. It can exploit several different parts of the forest rather than being restricted to one level.
That makes the rainforest less like a collection of separate floors and more like one enormous three dimensional ecosystem.
Wood quail are another hidden treasure
Panama is also home to wood quail, small forest birds that spend much of their time close to the ground.
They are considerably less famous than toucans or macaws, but for serious birdwatchers they can be extremely rewarding.
Wood quail tend to prefer dense forest environments where their small size and subdued colours make them difficult to see. A group moving through leaf litter can disappear remarkably quickly.
Again, listening becomes important.
Sometimes the first indication that these birds are nearby is not a clear view but the sound of movement through leaves.
Ground doves show that “ground bird” can mean many things
Panama also has several ground doves, which are much smaller and more familiar looking than curassows.
Ground doves can spend substantial amounts of time walking around searching for seeds and other food. They may occur around forest edges, clearings, gardens and other habitats rather than exclusively in deep rainforest.
They are a good reminder that ground dwelling isn't necessarily an extreme jungle adaptation.
Sometimes it simply means that a bird has found an excellent food source at ground level.
Why do so many birds live down there?
The forest floor may appear comparatively quiet, but biologically it is incredibly productive.
Dead leaves accumulate constantly. Fruits fall from trees. Seeds collect around roots. Insects, spiders and other invertebrates move through the leaf litter. Fungi break down organic material, and countless microorganisms participate in decomposition.
For a bird that knows how to exploit this environment, the ground can be an enormous food source.
Tinamous can search through leaf litter.
Ground doves can collect seeds.
Wood quail can forage through dense vegetation.
Curassows and guans can search for fruit.
Different birds are therefore exploiting different parts of the same ecosystem.
The forest floor is full of movement
Once you start paying attention to the ground, you realize that it is probably one of the busiest parts of the rainforest.
Leaf cutter ants march along established highways.
Beetles move beneath fallen leaves.
Agoutis search for fallen fruit.
Lizards dart between roots.
Frogs hide in damp vegetation.
Snakes move quietly through the litter.
And above all of this, birds are constantly searching for food.
The forest floor isn't an empty space underneath the trees.
It is a massive biological community.
Why these birds can be frustrating to photograph
Anyone who has tried photographing tropical wildlife knows that some animals seem almost designed to frustrate photographers.
Ground birds are particularly challenging.
The vegetation is dense. Light levels can be low. The birds are often moving through shadows. They may disappear behind leaves just as you raise your camera.
And the most secretive species often appear for only a few seconds.
You finally see the bird.
You lift your camera.
The bird moves behind a leaf.
You move slightly.
The bird disappears.
You wait.
Nothing.
Then you hear its call from somewhere behind you.
Welcome to tropical bird photography.
Panama is still teaching scientists about its birds
One of the fascinating aspects of Panama is that its birds have been studied for generations, yet there is still enormous scope for discovery.
The Smithsonian has maintained long term bird research programs in Panama, including extensive work on Barro Colorado Island and other locations. The country's scientific history includes the enormous surveys of Alexander Wetmore, whose multi volume work on the birds of Panama became an important foundation for later research.
More recent research continues to monitor bird communities and investigate how they respond to changes in forests and landscapes. In 2025, researchers involved with the Smithsonian Tropical Research Institute and the University of Wyoming were continuing long term bird monitoring in Panama, including work at Barro Colorado Island and Pipeline Road.
This is important because birds can tell scientists a great deal about the condition of a forest.
Changes in bird communities can reveal changes in food availability, habitat structure, predators and ecological conditions.
Barro Colorado provides an incredible natural laboratory
One of the world's most famous tropical research sites is Barro Colorado Island, in the Panama Canal watershed.
The island was created when the Panama Canal's Gatun Lake flooded the surrounding landscape, turning a former hilltop into an island. Scientists have been studying its wildlife for approximately a century.
That long history provides something extremely valuable: an unusually detailed record of how a tropical bird community changes over time.
The Smithsonian reports that the Barro Colorado bird community has lost around a quarter of its species over the period covered by its long term research, despite the island being protected from direct human disturbance for more than a century. The history demonstrates how complicated tropical ecosystems can be and how isolation can affect wildlife communities.
It also shows why protecting individual patches of forest isn't always enough. Animals depend on connections between habitats, food sources and larger landscapes.
The best way to find ground birds
If you're exploring Panama and want to improve your chances of finding these birds, slow down.
Walk quietly.
Stop frequently.
Listen.
Look at the edges of trails rather than only looking into the distance.
Watch for movement in leaf litter.
Pay attention to fallen fruit.
And don't immediately assume that a strange sound is an insect.
Some of the most interesting birds in Panama are deliberately living where most tourists aren't looking.
Early morning is particularly rewarding because the forest is cooler, wildlife is active and bird calls can carry through the vegetation before the heat of the day builds.
Don't forget the night
Although most of the classic ground fowl are daytime birds, nighttime adds another dimension to the forest floor.
After sunset, the insects become dramatically more active, and those insects attract predators. Frogs begin calling. Night birds become active. Mammals move through the vegetation. Reptiles start hunting.
This is why walking through a tropical forest at night feels so different from walking through it during the day.
You are not simply seeing the same forest without sunlight.
You are experiencing a different biological community.
A different way to experience Panama's wildlife
Panama's famous wildlife deserves its reputation. Toucans are spectacular. Sloths are unforgettable. Monkeys are entertaining. Hummingbirds are extraordinary.
But some of the country's most interesting birds are much less obvious.
A tinamou quietly calling from dense vegetation.
A wood quail moving through fallen leaves.
A guan searching for food beneath the trees.
A ground dove picking through seeds.
Or a massive curassow appearing unexpectedly on a jungle trail.
These birds make you slow down and pay attention to what is happening at your feet.
And that may be one of the best lessons Panama's rainforest can teach.
Don't always look up.
Sometimes the most fascinating wildlife is walking right beside you.
