It lives in warm forests. It has big eyes to see at night.

This bird hunts for bugs in the dark. It sits on a branch and waits. Then it flies out to catch a bug.

During the day, the bird stays very still. Its feathers look like wood. This helps it hide like a tree stump.

It does not build a nest. It lays one egg on a stump. The egg has spots on it.

Both parents help take care of the egg. They work together to keep it safe. It is a clever bird!

These birds live in warm forests in the Americas. There are seven different species of potoo. They are nocturnal, which means they are active at night.

During the day, potoos hide from danger. They sit very still on tree stumps. Their feathers have a pattern called cryptic plumage. This helps them blend in with the wood. If they feel scared, they use a freeze position. This makes them look like a broken branch.

Potoos have very large eyes to see in the dark. They hunt for insects like beetles and moths. A potoo sits on a perch and waits. When a bug flies by, the bird flies out to catch it. They swallow their food whole.

Potoos do not build nests. Instead, they lay one spotted egg on a stump. Both parents help keep the egg warm. The chicks also stay very still to hide.

The potoo is a very unusual bird from the Americas.

These birds belong to the family Nyctibiidae. They live in warm, humid forests from Mexico down to Argentina. You can also find them on islands like Jamaica and Tobago. Many people call them "poor-me-ones" because of their haunting calls. They are nocturnal, which means they are active at night. During the day, they stay very still to hide.

To stay safe, potoos use a clever way of hiding. They have cryptic plumage, which is a pattern of feathers that blends in. They often perch upright on tree stumps during the day. If they sense danger, they use a "freeze" position. This makes them look like a broken tree branch.

They do not build nests like many other birds. Instead, they lay one spotted egg on a stump. Both parents take turns keeping the egg warm. The chicks also stay very still to look like clumps of fungus.

When night comes, the potoo begins to hunt for food. They use their huge eyes to scan for movement in the dark.

They usually sit on a perch and wait for insects to fly by. When a bug appears, they fly out to snatch it. They eat things like beetles, moths, and grasshoppers. They swallow their prey whole without chewing it. This sit-and-wait method helps them save energy while they hunt.

Scientists have studied these birds for a long time. In 1853, French naturalists Jean-Charles Chenu and Œillet des Murs named the family. Fossils show that potoos lived in Europe a long time ago. One fossil from Germany is called Paraprefica. It lived during the Eocene period. This ancient bird had a skull similar to modern potoos. Researchers use DNA to study how the different species are related.

There are seven different species of potoo living today.

Some are large, like the Great Potoo. Others include the White-winged Potoo and the Rufous Potoo.

You might recognize their behavior if you have seen a flycatcher. Like those birds, potoos strike quickly from a perch. Their large heads and wide mouths make them look very different from other birds. They are truly special creatures of the forest.

Potoos are a unique family of nocturnal birds known as Nyctibiidae.

These birds are found in tropical Central and South America. They also live on Caribbean islands like Jamaica, Hispaniola, and Tobago. Potoos are highly specialized for life in humid forests. They are famous for their unusual appearance and haunting calls. Because of these sounds, some people call them "poor-me-ones." They are closely related to the oilbird, which belongs to the Sedentaves subclade.

The physical design of a potoo is built for survival in low light. They have proportionally large heads for their body size. These heads feature massive, broad bills and enormous eyes. One expert described them as being "little more than a flying mouth and eyes." The bill is short and delicate, but it has a unique "tooth" on the upper mandible. This structure may help them while they are foraging for food. Unlike true nightjars, potoos lack rictal bristles around their mouths. Their eyes are even larger than those of nightjars. These eyes reflect flashlight beams and have special slits in the lids. These slits allow them to sense movement even when their eyes are closed.

Potoos use a specific hunting method called a sit-and-wait strategy. They are nocturnal insectivores, meaning they eat insects at night. During the day, they perch upright on tree stumps to hide. They use cryptic plumage, which is a pattern of feathers that blends with surroundings. If they detect danger, they adopt a "freeze" position. This movement makes them look like a broken tree branch.

At night, they hunt from a perch like a flycatcher. They scan the dim sky for the silhouette of moving prey. Their diet includes beetles, moths, grasshoppers, and termites. When they catch an insect, they swallow it whole. They do not crush or beat their food. This method allows them to hunt while using very little energy.

There are seven distinct species within the Nyctibiidae family. These species are divided into two different genera. One genus is Nyctibius, which includes the Great Potoo and the Common Potoo.

The other genus is Phyllaemulor. This genus was created after a 2018 study found a deep genetic divergence. The Rufous Potoo is a member of this new genus.

Other species include the Long-tailed Potoo, the White-winged Potoo, and the Andean Potoo.

The Northern Potoo was once thought to be the same as the Common Potoo. However, scientists separated them based on their unique calls.

The history of the potoo includes a much wider global range. Fossil evidence shows they lived in Europe during the Paleogene period.

In Germany, researchers found fossils of the genus Paraprefica in the Messel pit. This genus belonged to an extinct subfamily called Parapreficinae. The Paraprefica fossils had skull and leg features similar to modern potoos. Another fossil, Euronyctibius, lived in France during the Oligocene. While it was once thought to be a potoo, it is actually a relative of the oilbird. Scientists use mitochondrial DNA to study these evolutionary relationships. A 1996 study showed that potoo species are very old. The genetic divergence between them is higher than in most other bird genera.

Reproduction for potoos relies heavily on their ability to remain unseen. They are monogamous breeders, meaning they form pairs for the breeding season. They do not build traditional nests. Instead, they lay a single, spotted egg directly on a tree stump. Both parents share the work of incubating the egg and raising the chick. The egg is white with purple-brown spots. It hatches about one month after it is laid. The nestling phase lasts for two months. This is a long time for a landbird. Young chicks have white plumage. They stay still to look like clumps of fungus to avoid predators.

Potoos have many different names depending on the region. In Argentina, they are called kakuy or cacuy. This comes from the Quechua word meaning "to remain." In Bolivia, they are called guajojo because of their call. In Brazil, Uruguay, and Paraguay, they are known as urutaú. This name comes from the Guarani words for "bird" and "ghost."

These names reflect how humans perceive their mysterious nature. Their presence is a vital part of the Neotropical forest ecosystem. They connect the world of insects to the larger food web of the Americas.
