Some live in trees. Others live on the ground.
Most cuckoos eat bugs. They like to eat hairy bugs.
They rub bugs on branches to eat them.
Some cuckoos are very special. They lay eggs in other birds' nests. The other birds then raise the babies.
Many cuckoos fly far away. They move to find warm weather. Some fly over the big sea.

Cuckoos are a large family of birds. There are 150 different species.
Most cuckoos live in trees. Some species live on the ground. Ground birds like roadrunners have long legs. They have heavy bodies.
Cuckoos have a special way of using their feet. They are zygodactyl. This means two toes point forward and two point back. Most cuckoos eat insects. They especially like caterpillars. They rub bugs on hard branches. This helps them crush the prey before they eat it.
Some cuckoos are brood parasites. This means they lay eggs in the nests of other birds. Those birds then raise the cuckoo babies. Some cuckoo babies even look like the host birds.
Many cuckoos fly very far. They migrate to find food and warmth. The long-tailed koel flies across the ocean. The common cuckoo flies over the Sahara Desert.
Cuckoos are a large and diverse family of birds. They belong to the family Cuculidae. This family includes about 150 different species. These birds live all over the world. They can be found on every continent except Antarctica.
Many species live in warm, tropical forests. Others live in more open places like deserts. Some cuckoos even live in mangrove forests. They are very successful living things.
Cuckoos have many different ways of living. Most species are medium-sized and slender. Many live in trees, which are called arboreal species. These birds often have long tails to help them steer. Other cuckoos live on the ground. These terrestrial species are often heavier. They have long legs to help them move.
A special feature is their feet. They are zygodactyl, which means two toes point forward and two point back. This helps them grip branches or move on land.
Feeding is a very interesting part of their lives. Most cuckoos eat insects and caterpillars. They have a special way to eat them. They rub the insect on a hard branch. Then they use bony plates in their mouths to crush it.
Larger cuckoos like roadrunners eat more things. They might eat snakes, lizards, or small rodents. Some species, like the Asian koel, mostly eat fruit. This shows how much variety there is in the family.
Some cuckoos are famous for being brood parasites. This is a way of life where they lay eggs in the nests of other birds. The other birds then raise the cuckoo chicks.
This happens with many species in Eurasia. Some chicks even look like the host birds. For example, Asian koel chicks are black to match crows. In Australia, some chicks are brown to match honeyeaters. This helps them stay safe in the nest.
Cuckoos have also been part of human stories for a long time. In Greek mythology, they were sacred to the goddess Hera. In Japan, they represent unrequited love. Some cuckoos are also amazing travelers. The long-tailed koel flies from New Zealand to places like Polynesia.
The common cuckoo flies over the Mediterranean Sea and the Sahara Desert. These long trips help them find food and warmth. It is a wonderful way to see the world.
Cuckoos are a diverse group of birds belonging to the family Cuculidae. This family is the only group within the order Cuculiformes. It contains approximately 150 different species divided into 33 genera. Cuckoos are found across the entire world, except for Antarctica. While many species live in tropical rainforests, others inhabit deserts or mangrove forests. They play important roles in their ecosystems as predators and travelers.
A defining physical feature of the cuckoo family is their zygodactyl feet. This means the two inner toes point forward while the two outer toes point backward. This foot structure helps them grip branches or navigate the ground. Cuckoos generally fall into two body types based on their lifestyle. Arboreal species, such as the common cuckoo, are slender with short tarsi, or lower leg bones. These birds use their long tails as a rudder during flight. Terrestrial species, like the roadrunner, are more heavy-set with long tarsi for walking.
The family is organized into several distinct subfamilies. The Cuculinae are the brood-parasitic cuckoos of the Old World. They typically have long tails, short legs, and long, narrow wings for life in trees. The Phaenicophaeinae includes nonparasitic cuckoos like malkohas and couas. These birds are often more terrestrial and have brighter plumage or colorful skin around their eyes.
The Coccyzinae are also arboreal and include many large island species. Finally, the anis are an atypical group with massive bills and glossy feathers.
Many cuckoo species are famous for being brood parasites. This is a process where they lay their eggs in the nests of other bird species. The host parents then raise the cuckoo chicks instead of their own. In Eurasia, many species follow this strategy. Some cuckoos even use mimicry to survive. For example, some species have plumage that looks like hawks to alarm potential hosts. The chicks of some parasites even match the color of their hosts. Asian koel chicks are black to match crows, while Australian koel chicks are brown to match honeyeaters.
Cuckoos are highly specialized feeders. Most are insectivores that prefer large insects and caterpillars. They often eat hairy or noxious caterpillars that other birds avoid. Cuckoos have a unique way of processing prey. They rub insects against hard objects like branches. Then, they use special bony plates in the back of their mouths to crush the prey.
Larger species, such as coucals and roadrunners, eat more diverse animals. They may hunt snakes, lizards, or small rodents. Some use their strong bills to bludgeon their prey.
Migration is a major part of life for several cuckoo species. While most are sedentary, others travel vast distances to find food or warmer weather. The long-tailed koel performs a remarkable overwater migration from New Zealand to Polynesia. The yellow-billed cuckoo flies 1,500 miles nonstop across the Caribbean Sea. The common cuckoo flies nonstop over the Mediterranean Sea and the Sahara Desert. These journeys require incredible physical strength and endurance.
Cuckoos have deep connections to human history and culture. In Greek mythology, they were considered sacred to the goddess Hera. In India, they are linked to Kamadeva, the god of desire. In Japan, the cuckoo symbolizes unrequited love. In Europe, the bird is often a symbol of spring. The term "cuckold" actually comes from the way these birds lay eggs in other nests. This long history shows how much humans have observed and wondered about these birds.
