What Do Cuckoo Birds Eat? — Forest Wildlife
You may have heard about the cuckoo’s song or their strange nesting habits, but did you know that their eating habits can be every bit as interesting? Cuckoos are not picky when it comes time to feed, and at times, their need for protein can drive some pretty odd behaviors. So, what do cuckoo birds eat? In this article, we’ll answer that question and more.

What Foods Do Cuckoo Birds Eat?
Cuckoos are generally considered insectivores, meaning they mostly eat insects. However, when food is scarce, they will eat a variety of things.
According to Audubon, cuckoos tend to hunt for insects in the branches of trees and shrubs, but they will sometimes catch flying insects in midair.
A cuckoo’s favorite food appears to be caterpillars, especially the plump, fuzzy or hairy varieties. They aren’t particular about which kids they like, as they will often eat caterpillar species that other birds will avoid.
Cuckoos tend to eat insects that are destructive to crops and plant life, such as the cabbage white butterfly and its larva. They will also eat a variety of moths and butterflies, as well as some types of spiders and centipedes.
Some cuckoos eat more than just insects and invertebrates. They may be driven to seek out other food sources during times of drought or famine, or they may simply adapt to eating a wider variety of foods based on what’s available in a given region.
Some alternate food sources of cuckoos include lizards, snakes, and small rodents such as mice. Some cuckoo species will even eat fruit and berries.
With so many food options available, cuckoos are rarely threatened with the possibility of starvation.
What Does a Baby Cuckoo Eat?
Cuckoos are known as brood parasites; this means they lay their eggs in the nests of other birds, which then raise the young cuckoos as their own.
Because of this, baby cuckoos eat whatever they are fed by their host parents.
Young cuckoos are often raised by meadowlarks and reed warblers, both of which tend to feed worms and insects to their young. Depending on the species of the host parent, young cuckoos may be fed whole insects or food regurgitated by the parent.
It is possibly at this young stage of life when cuckoos learn to eat a variety of foods, as they may also be fed bits of fruit and many different invertebrates. Like the adults, young cuckoos are generally not picky about what they’re given to eat, as long as they receive a steady supply of it.
Do Cuckoos Eat Other Birds?
We’ve established that cuckoos eat a lot of different things. They may even be considered opportunistic eaters, as they will eat whatever’s available to them if food is scarce.
This begs the question: will they eat other birds?
Most cuckoos do not stoop to this level of semi-cannibalism, but there have been rare occasions when large cuckoos have been spotted eating birds of smaller species or their chicks.
It is fairly common for cuckoos to eat the eggs of other birds, but they rarely eat other adult birds. When laying eggs in another bird’s nest, a cuckoo may steal one of the existing eggs and either eat it or push it over the edge of the nest.
Sometimes, cuckoos will eat baby birds. While it’s unclear what drives this behavior, it may be due to food shortage or because the cuckoo plans to lay an egg in the nest and feels the need to remove the existing young.

How Much Do Cuckoo Birds Eat?
There are around 140 different cuckoo species, and they vary widely from about 6 inches long to over 30 inches.
Some weigh less than an ounce, while others weigh well over a pound.
With such a wide range of birds and sizes, it’s impossible to say exactly how much a cuckoo eats on a regular basis. It may also be affected by factors such as season, habitat, and the type and quality of food available.
Generally, smaller birds require more food relative to their body weight. They need to eat more during cold weather because the higher calorie content helps them keep warm.
What’s more, cuckoos tend to eat more of the foods they like when food is plentiful. They may eat less of whatever is available if they don’t have a consistent supply of the caterpillars they enjoy so much.
Conclusion
Cuckoo birds are insectivores that will eat a variety of other foods if need be. They prefer plump, hairy caterpillars, but they also regularly eat butterflies, spiders, grasshoppers, cicadas, centipedes, and many other invertebrates.
Sometimes, they will even eat small rodents, lizards, and other animals, as well as some types of fruit.
They have even been known to eat the eggs and young of other birds.
Cuckoo Bird - Description, Habitat, Image, Diet, and Interesting Facts
Cuckoo birds are medium-sized birds that are most well known for their parenting skills, or lack thereof. Some species of these birds are brood parasites. This means that the female finds another bird’s nest, waits until the other bird is gone, and lays her own egg inside! The unsuspecting bird returns to her nest and incubates the cuckoo’s egg, then cares for the chick when it hatches. Read on to learn about the cuckoo bird.
Description of the Cuckoo Bird
There are many different cuckoo species, and their appearance ranges greatly by species. While some birds are dull grey and unremarkable, others are bright green with burnt orange patches. They range in size as well, from the 6 in. long little bronze, to the 25 in. long channel-billed. They can also range anywhere from about 1/2 oz. to 1.5 lbs. in weight! Some species are slender and lean, while others are heavier with larger feet.
Interesting Facts About the Cuckoo Bird
Undoubtedly, the most interesting fact about the cuckoo is it’s strange nesting habits. While not all species are brood parasites, this behavior is certainly quite intriguing. The lack of parental skills in some species is, however, not the only interesting facts about these creatures.
- Counting Crows – Birds spend a lot of time feeding their young, and wasting that time caring for someone else’s baby is not acceptable! Some birds can count the number of eggs laid in their nests, and will toss the extra egg out. To combat this, when a cuckoo bird lays an egg in another bird’s nest, it usually pushes one egg out, and replace it with their own.
- Brutal Babies – The battle for the nest doesn’t end when the chicks hatch. Cuckoo chicks will actually push the other eggs and baby birds out of the nest! This lets them keep all the food for themselves, making them more likely to survive.
- Varied Lifestyles – Different species can have very different lifestyles.
Sometimes these birds live a typical tree-going lifestyle, which is called arboreal However, some species spend much of their time on the ground searching for food, which is called terrestrial behavior. - Tip-Top Toes – Another interesting trait that these birds possess is zygodactyl feet. No, they aren’t dinosaurs, but they do have an odd toe arrangement. Instead of three toes forward and one toe back, they have two forward and two back. Parrots share this unique trait with the Cuckoo.
Habitat of the Cuckoo Bird
The many different species occupy a surprisingly wide range of habitats. Most live in forested areas and woodlands, and the highest diversity is found in evergreen rainforests in the tropical regions. Certain species are also fond of, or even restricted to, life in mangrove forests. These birds can also be found in wetlands, moors, and even deserts.
Distribution of the Cuckoo Bird
Cuckoos are incredibly widespread, and they can be found on every continent except Antarctica.
It is actually easier to note where these birds are absent than where they are found. There are none on the south west side of the Andes Mountains in South America, northern North America, the Sahara Desert in Africa, and the driest areas of the Middle East.
Diet of the Cuckoo Bird
While there is a decent amount of variation, most cuckoos are insectivores. That means that they feed primarily on insect species. Their favorite food is caterpillars, and they are capable of eating a number of species that are usually avoided by other birds. Some species also feed on lizards, snakes, small rodents, other birds, and fruit.
Cuckoo Bird and Human Interaction
These birds have different human interactions based upon the species. Some species are more threatened with hunting for meat and feathers than others. All are threatened to some degree by deforestation, expansion of urban areas, and climate change. Climate change in particular can cause decreases in prey species, and this effect can vary based upon how specialized the species’ diet is.
Domestication
Cuckoos have not been domesticated in any way.
Does the Cuckoo Bird Make a Good Pet
These birds are wild animals, and do not make good pets. In most places it is illegal to own a cuckoo bird as a pet.
Cuckoo Bird Care
In zoos, the care of these birds can vary quite widely depending on the species. Those that are arboreal are provided with plenty of flying opportunities, a variety of perches, and tall growing plants in their habitats. Those that are terrestrial are given more bush-like foliage, plenty of hiding places, and substrates similar to those in their natural habitat. Their diets replicate those they have in the wild as closely as possible.
Behavior of the Cuckoo Bird
The vast majority of species are solitary, and can be spotted in groups or pairs only on rare occasions. Most are diurnal, which means that they are active during the day, but a few species will also vocalize at night. For the most part these birds are quite shy, avoiding human contact and hiding within relatively dense vegetation.
Reproduction of the Cuckoo Bird
The breeding habits of different species vary extensively. Some have extremely short incubation periods, some leave the nest before they are even able to fly, and some have relatively unremarkable chick-rearing patterns.
The most famous breeding strategy is the brood parasitism discussed above, but they also have another interesting breeding habit: a few species will breed in a communal nest. All members in the group will help build the nest, incubate the eggs, and rear the chicks.
Beliefs, Superstitions, and Phobias About the Cuckoo Bird
In Greek mythology, the goddess Hera believed the cuckoo bird to be sacred. The Greek god Zeus transformed himself into a cuckoo to woo Hera to his affection. These birds are also commonly referenced in the works of William Shakespeare, as a symbol of the upcoming spring and fertility.
appearance and distribution of the bird, food for it
The cuckoo is one of the hidden birds that are not only shy, but also like to hide.
Therefore, it is quite difficult to see them. The way of life that they lead is also interesting, and the food of cuckoos deserves special attention. Further in the article, we will tell you in more detail about this bird.
Appearance of the cuckoo
The common cuckoo weighs about 100 grams and is 40 centimeters long. Male and female differ in plumage color. So, the back of the male is dark gray, and the rest of the body has a light gray and white plumage with stripes. The beak of such an individual is black and slightly curved, and its legs are short.
The females have brownish plumage, but the rest are rusty-red and with white or black stripes. In young individuals, it is impossible to determine the sex by plumage, since they are either gray or red, but they always have dark stripes throughout the body.
Distribution of the common cuckoo
Cuckoo fairly widespread . It usually breeds in the following territories:
- Europe.
- Africa.
- Asia.
- Arctic Circle. Cuckoo is a migratory bird deserts, and even high above sea level. During the flight, they move in a northeasterly direction and cover a path equal to 80 kilometers in a day.
In Russia, these birds, as a rule, appear at the end of May - July . They settle almost everywhere, except for the northern tundra. The favorite places of the common cuckoo are forests and parks, forest edges and glades, coastal thickets and low bushes.
Reproduction of the common cuckoo
Cuckoos try to put their eggs in such nests, where they would correspond to those eggs laid by the owners of the nest themselves. Compliance is usually determined by both color and size. At first, she observes a little how the nest is being built, choosing in advance those to whom she can lay her eggs. When egg-laying begins at the owners of the nest, the bird flies up to the nest, takes out one egg with its bent beak, eating it or taking it with it, and lays its own.
This procedure of tossing your egg in the common cuckoo lasts no more than 10 seconds. It is worth noting that a female can produce up to 20 eggs in one summer, but only 5 eggs can be thrown from them. If she does not find a nest, then she leaves her egg right on the ground or in some abandoned nest. If necessary, the female is able to hold an egg for several days, which is already ready for demolition.
Rare feathered nest owners notice egg substitution. But the embryo in the cuckoo egg develops very quickly and already on the 13th day they are ready to hatch from the shell. They hatch naked and blind. At first, little cuckoos are very similar to the chicks of their foster parents, sometimes even the voice becomes similar to the sounds made by foster parents. The hatched cuckoo has a sensitive back and a small depression in the coccyx area. If one of the chicks touches him, then with this recess he can throw the egg or the chick itself out of the nest.
Little cuckoo is very demanding : he often and widely opens his orange mouth, demanding food. Due to the constant demand for food, the cuckoo nest owners do not even have time to see the fall of the chick and help him, and sometimes they simply ignore this fall. The cuckoo is growing very fast. It is known that already on the 22nd day he not only exceeds the size of his adoptive parents, but also at this time he leaves the nest. But the owners of the nest rush after him, feeding him with insects for several more weeks.
Lifestyle of the common cuckoo
Male cuckoos immediately occupy a fairly large area , attracting females with their loud and ambiguous calls. Thanks to this cuckooing, this bird got its name. Females are not so melodic and prefer to be silent more, but sometimes in flight they can also make a ringing trill, attracting males for mating.
The male flies around his territory to mate with the females in turn.
Females are distributed in a specific area, where they are trying to find foster parents for their future offspring in advance. In summer, these birds, as a rule, are alone: they do not build nests, do not incubate eggs, and the mating season is already ending at this time. To date, over 120 species of birds are known, in whose nests the cuckoo has ever thrown its eggs. But usually they try to select sparrow songbirds. Therefore, cuckoo eggs are so easy to throw into the nests, because they match in size and color. It is known that if a female cuckoo has grown in the nest, then next summer she will return to the area where her foster parents' nest was, remembering the appearance of those who raised them. Young growth begins to breed later than the old bird. By the way, the life expectancy of a cuckoo in the wild does not exceed 5-10 years.
Food of the common cuckoo
It is known that the cuckoo, as well as its cubs, is very voracious .
But what does she eat? It is worth noting that cuckoos are the kind of bird that is not picky about food. The main food for this bird is insects and their larvae. She especially loves furry caterpillars, eats them in large numbers. But many birds avoid eating such hairy caterpillars. Among the insects that the cuckoo eats, there may be beetles, butterflies, filly, rider. They also eat bird eggs, and sometimes they can eat berries. The diet of cuckoos is very different from that of other insectivorous birds . In order to more fully imagine the diet of this bird, a whole study was conducted in Russia, where everything that this bird ate per day was tracked. The result of this study showed that the common cuckoo in central Russia in one day can eat the following food:
- Young lizards - 18 pieces.
- Large green grasshoppers - 40 pieces.
- Butterfly pupae "Dead head" - 5 pieces.
- Cabbage worms - 45 pieces.
- May beetle larvae - 5 pieces.
- Meal worms - 50 pieces.
- Ant eggs - unlimited.
Another study was done where the cuckoo was fed only caterpillars. It turned out that in one day she is able to eat more than 1900 of them.
Of course, the cuckoo stands out from the rest of the bird world , because the very way of her life is unusual. But, despite all the difficulties, the population of this bird is quite stable and the number of cuckoos today is not decreasing at all. It is worth noting that the cuckoo is still a useful bird, since it easily finds those places where insects breed or live and contribute to suppressing this very dangerous center of their distribution.

Forest saboteurs: a spy detective written by nature
***
Like every true detective story, this one also started on a sunny summer morning, so serene that even the word "detective" would never have occurred to anyone.
It wouldn't have come to me because I was five years old, to my grandfather - because who thinks about detective stories on such a wonderful morning?)So, going for strawberries. In a forest clearing, a scattering of small berries, I collect them in a toy bucket for a sandbox. Most of the berries go into the mouth, of course (mmm ... yummy!), But even in the bucket the bottom is almost covered. It’s getting hotter, I’ve eaten strawberries, I don’t feel like collecting more at all. In addition, there are so many interesting things around for a little city girl!
The first thing I found was an ant track. A whole trail of ants! With two-way traffic, as expected.
In one direction, the ants carry some small pieces. I went along the ant path in this direction - an anthill! They drag what they find there, and return for new prey.
***Went after the ants going the other way. I'd rather not go.
Seen - shock. Among the broken shells, several dead tiny chicks wallow in the grass under a tree, and ants drag pieces of their bodies for their pupae. And above among the branches is a nest. Probably, these poor chicks fell out of there. I burst into tears, grandfather came running.Seeing the reason for my tears, he said:
– The cuckoo spoils.
- How does he pamper, grandfather?
-- Cuckoo is a very lazy mother. She finds someone else's nest and throws her chick there: let others raise it. And the cuckoo hatches earlier, besides, it is stronger and more cunning than the native chicks of the nest into which it was thrown. A growing cuckoo needs a lot of food, so he gets rid of competitors, throwing them out of the nest.
Look up, just stand quietly. See? Birds carry cuckoo food. They drag the worms and caterpillars one by one, and he keeps screaming and demanding more and more. This is how it turns out that native children die, and the foundling cuckoo grows in warmth and care. Do not Cry! In nature, everyone is in store, and each has its own place and its own time. Despite the tears and pity for the dead chicks, I still wondered: how does a cuckoo throw up a chick? After all, Grandpa only said that a foundling always hatches first and pushes native cuckoo babies out of the nest.
In general, grandfather's answer was already exhaustive, and then I found the details myself.
But what details! Intelligence all over the world is jealous, looking at the work of feathered special agents under the code name "cuckoo".The cuckoo family operates according to all the rules of covert military operations. Each action of the assault brigade (cuckoo-mother - an agent of penetration, cuckoo-dad - distracting maneuvers) is debugged by nature and inscribed in the genetic memory of birds to the smallest detail.
So, everything starts with exploration.
The operation goes according to plan: having found a replacement nest, the cuckoo forms an egg and begins to follow the owner of this nest. A schedule of movements is drawn up, routes are being followed, and most importantly, observations are being made in order to see exactly when the female will lay her eggs.
(stock photo)
At the moment when the female from the target nest lays eggs, the mother cuckoo also lays her egg for the replacement operation. But not right away: cuckoos have a special talent to keep a ready-made egg in the ovipositor for another day. These additional days of the egg being in the forty-degree body of the mother give the future cuckoo a huge head start in development and provide it with the opportunity to appear first in the nest of foster parents.When the time comes to complete the operation and replace the egg in someone else's nest with your own, the cuckoos put on a whole show.
While the mother cuckoo, hiding nearby, watches the nest with all her eyes, the father cuckoo pretends to be a hawk or some other feathered predator. It turns out very similar: the cuckoo forges the calls of all local predators skillfully, and in color and size it is already very similar to a predator. While the cuckoo dad is circling over the nest of future caregivers of his children, pretending to be a hawk and distracting from the nest, the cuckoo mom lays her egg almost instantly, in just 15-20 seconds.
Most likely, birds can count. Because something makes the cuckoo cover its tracks: having laid an egg in someone else's nest, it either takes one of the host's ones with it, or simply eats it.
***
The fact that cuckoo eggs every time look like eggs in the nest of victims of substitution is simply explained: during the life of a cuckoo, she practices substitution for only a few species of birds, and gene memory does not give her a mistake with color.
The same gene memory dictates to a newly hatched cuckoo: get rid of your opponent. As soon as you touch another egg, immediately throw it out of the nest. How? Yes, very simple. Rest the recess between the wings in the egg, and push up and to the side. Fall out! And nothing that he himself is a tiny newborn. There is enough strength even to push out an egg or chick 2-3 times heavier than itself.
***
If, nevertheless, it was not possible to push out the eggs from which future rivals in feeding will hatch, the gene memory, without letting up, dictates further: push the chick out. Just the same, a hollow between the wings. Adapt to it, and, straightening your legs, as if on a shovel, and you're done: one less freeloader. The memory laid down by generations of cuckoos does not allow a tiny cuckoo to relax until he gets rid of all the chicks in the nest. Those eggs that he could not push out, the chick just pecks. After that, the chick in the egg dies: not by washing, so by rolling, the cuckoo still achieves its goal.
Why does cuckoo's nature make you get rid of other chicks? Fight for survival, of course. The cuckoo needs a lot of food. Incredibly many for those species of birds that cuckoos replace. In order to have enough food for the cuckoo, which grows 30 (!) times in just a month, there should be no applicants for feeding in the nest at all.
But even if something in the cuckoo's program went wrong and he couldn't get rid of the rest, he still wins: a feeding marker for birds - a yellow stripe for babies and a cry. The cuckoo always has the brightest sallowness, and he gets food more often and more than others. And the cuckoo knows the sounds that native chicks should make even before they hear them. Again, thanks to the same gene memory.
***
As for the bird-caregivers, their own gene memory does not allow them to stop feeding the baby. Even when the two adoptive parents, exhausted, carry food all day long, and he keeps screaming and screaming from hunger, they still feed him.
And when the cuckoo grows more than the nest, they feed too.
***Even if the nest falls apart under the weight of a foundling, even then the poor birds continue to feed it where it sits. And they feed until the adopted child gets stronger and flies away.
But don't blame all cuckoos for being bad mothers. There are times when cuckoos fly to feed their baby in someone else's nest, and they feed not only him alone, but also the surviving chicks of the owners too. And sometimes the cuckoos simply "evict" the inhabitants of the nest, taking it for themselves, and they themselves raise their chick there.
A video showing the operation of a cuckoo inserting its egg into someone else's nest:
And in conclusion, a bonus to all who have read to the end)
An interesting interesting thing about cuckoos waving about our life span: according to the research of the Russian ornithologist A.S. Malchevsky, the number of two-syllable elements “cuckoo” in the calling monologue of a male cuckoo can reach up to 360.
