The Colombian chachalaca (Ortalis columbiana) is a type of bird that lives only in Colombia. It belongs to a bird family called Cracidae. These birds live in forests and woodlands found in the valleys between the Andes Mountains. Colombian chachalacas mostly eat fruit. They spend most of their lives in trees. By eating fruit and spreading seeds, they help keep the tropical forests healthy and full of different plants.

Discovering the Colombian Chachalaca
This bird was first officially described in 1906. An Austrian bird expert named Carl Eduard Hellmayr gave it its scientific name. He studied bird samples kept in a museum in Bavaria. These samples were collected during an expedition to South America between 1817 and 1820.
Hellmayr noticed that these birds looked different from another type of chachalaca. This other type, the Speckled chachalaca, had been described earlier. Today, most experts agree that the Colombian chachalaca is its own unique species.
What Does It Look Like?
The Colombian chachalaca is a typical Ortalis bird. It is a large, plump forest bird. It has a long, thin neck and a small head. Its legs are long and strong, and it has a long tail.
Size and Weight
Adult Colombian chachalacas are about 50 to 60 centimeters (20-24 inches) long.
- Male birds have wings about 22.5 cm (9 inches) long.
- Female birds have wings about 19.6 cm (7.7 inches) long.
- Their tails are usually around 24 to 25 cm (9.4-9.8 inches) long.
- Males typically weigh about 600 grams (1.3 pounds).
- Females are a bit lighter, weighing around 500 grams (1.1 pounds).
Colors and Features
Both male and female chachalacas look very similar.
- Their upper body is mostly brown.
- The wing feathers (primaries and secondaries) are grayish-brown.
- The outer tail feathers are a reddish-brown color.
- Their head and neck are grey.
- They have a red patch of skin on their neck called a dewlap.
- The feathers on their chest are grey with clear white scalloped patterns. This helps tell them apart from similar birds.
- Their belly is a light yellowish-brown.
- The feathers on their thighs and under their tail are reddish-brown.
- Their legs and feet are pinkish.
- The beak is dark grey at the base and white at the tip.
- Their eyes are dark brown.
- There is a patch of grey bare skin around each eye.
Where It Lives and Its Home
The Colombian chachalaca lives only in the Cauca and Magdalena valleys of Colombia. It used to be found in many more places. However, over the years, hunting and losing their natural homes have made their numbers drop.
Now, they live in smaller, separate groups. You can find them in the upper parts of the river valleys. For example, in the Magdalena valley, they live from Huila Department to Santander. In the Cauca valley, they are found from Cauca Department to Antioquia.
These birds prefer to live on the edges of forests. They like dry to humid forests and older second-growth areas. They can even survive in places where the habitat is not perfect. This includes areas with bushes and thickets. They can also live near people if they are not hunted. However, they do best in older, more natural forests. Here, they can use fallen tree trunks for food, shelter, and nesting among tree roots.
How It Behaves and Lives
Colombian chachalacas spend most of their time in trees. They usually look for food from the middle to the top parts of the forest. They like trees that have plenty of food, especially Ficus or Cecropia trees. They can fly short distances between trees but usually do not fly far.
These birds are social animals. They often live in groups, and sometimes up to 20 birds can be seen together. They can be quite loud! They often make a "chac-a-lac" call together. This is how they got their name.
Breeding Habits
Not much is known about how these birds raise their young. It is thought that Colombian chachalacas stay with one partner. They might also protect their own area during breeding season. In the Magdalena valley, signs of breeding were seen in February. This included a female ready to lay eggs, a male ready to breed, and a young bird that was half-grown.
What They Eat
Colombian chachalacas, like other birds in the Cracidae family, eat a lot of fruit. Birds that eat large fruits are very important for tropical forests. When they eat fruit, they spread the seeds through their droppings. This helps new plants grow far from the parent plant. If these large fruit-eating birds are not around, the forest might become less diverse. It could be taken over by fast-growing plants with smaller fruits and seeds.
These birds usually look for food in pairs or small groups. In the Cauca valley, scientists found that their diet included 26 different types of plants.
- Fruits made up most of their diet (77.2%).
- Leaves were also eaten (16.2%).
- Flowers were a smaller part (3.6%).
- They also sometimes ate soil, dead leaves, and small stones (3%).
Studies showed that many seeds passed by Colombian chachalacas grew better than seeds taken directly from the fruit.
Current Status and Threats
The Colombian chachalaca is listed as a Least Concern species by the IUCN Red List. This means it is not currently in danger of extinction. While its numbers and living areas are shrinking, the decline is not fast enough to be considered "Vulnerable" yet. Also, even though we don't know the exact number of birds, it doesn't seem to be below the level for a "Vulnerable" rating. The species can also handle living in less-than-perfect habitats and near people.
Main Threats
While large birds of prey like the Ornate hawk-eagle might hunt them, the biggest danger to Colombian chachalacas comes from humans. Hunting by people is the main threat. Losing their forest homes and their habitats becoming broken up are also major problems.
Conservation Efforts
Currently, there are no specific conservation activities just for the Colombian chachalaca.
