Are Pigeons Mammals


Are Pigeons Mammals: Pigeons, those ubiquitous birds that often grace our urban landscapes, are creatures of fascination and curiosity. While it may seem like a straightforward question to ask whether pigeons are mammals or not, the answer is not as obvious as one might think. Pigeons are indeed fascinating creatures, and their classification within the animal kingdom reveals much about the complexity of life on Earth. To begin our exploration, we must first understand what distinguishes mammals from other animals. Mammals, as a class of vertebrates, share several key characteristics. First and foremost, they are warm-blooded, meaning they can regulate their body temperature internally. 

They also possess mammary glands, which allow females to nurse their young with milk. Hair or fur covers their bodies, even if it’s sometimes minimal, and they typically give birth to live offspring, rather than laying eggs. Now, let’s turn our attention to pigeons. Pigeon sleep, also known as rock doves, belong to the avian class of animals, characterized by feathers, beaks, and the ability to lay eggs. Unlike mammals, birds are ectothermic, meaning they rely on their environment to maintain their body temperature. They lack mammary glands and do not produce milk to nourish their offspring. 

Instead, baby pigeons are fed with a specialized secretion known as “pigeon milk,” produced in the crop of the parent birds. Pigeons are not mammals; they are avian creatures belonging to the class Aves. While they share our terrestrial habitats and often interact closely with humans, their biology and classification place them firmly within the world of birds, setting them apart from the warm-blooded, milk-producing, fur-covered creatures we identify as mammals. As the world of pigeons, we will discover their fascinating behaviors, unique adaptations, and their significance in human culture and history. 

Are Pigeons Mammals

Do pigeons give milk?

The pigeon is one of only three bird species (the others being flamingos and male emperor penguins) known to produce ‘milk’ to feed their young. In pigeons the milk starts to be produced in the crop of the parent birds two days before eggs hatch.

Crop Milk Production: Before hatching, the adult pigeon’s crop undergoes significant changes in preparation for feeding the chicks. The walls of the crop become highly glandular, and they produce a nutritious, milky substance. This substance is rich in fat and protein, providing essential nutrients for the growing chicks.

Feeding Chicks: After hatching, the parent pigeons feed their chicks by regurgitating this crop milk directly into their mouths. The crop milk is soft, easily digestible, and contains the nutrients needed for rapid chick growth. It is essential for the early development of the chicks’ bodies and feathers.

Gradual Transition: As the chicks mature, their diet gradually transitions from crop milk to solid food. The parents incorporate seeds and other food items into their regurgitations, helping the chicks adapt to a more varied diet.

What is a mammal and not a bird?

Bats are mammals because, like all mammals, they make milk for their young. Bats are not birds because they don’t have feathers, they don’t lay eggs, and are built very differently from birds. A bat wing doesn’t look anything like a bird wing, for instance.

Mammals are endothermic, meaning they can regulate their body temperature internally. They generate heat through metabolic processes and maintain a relatively constant body temperature regardless of external conditions. This ability allows mammals to inhabit a wide range of environments, from polar ice caps to scorching deserts.

Birds are also endothermic, much like mammals, and have the ability to regulate their body temperature. However, their temperature range is often slightly higher than that of mammals, typically between 100 and 110 degrees Fahrenheit.

One of the most defining characteristics of mammals is their reproductive strategy. They give birth to live offspring, which are nourished through the mother’s mammary glands, producing milk. This unique method of feeding ensures that mammalian young receive essential nutrients and care during their early stages of life.

Birds, on the other hand, reproduce by laying eggs. While they also care to their offspring, the process involves incubating the eggs until they hatch. Once hatched, young birds are typically fed regurgitated food by their parents.

Do pigeons lay egg?

Female pigeons can reach sexual maturity as early as 7 months of age. Pigeons build a flimsy platform nest of straw and sticks, put on a ledge, under cover, often located on the window ledges of buildings. Eight to 12 days after mating, the females lay 1 to 3 (usually 2) white eggs which hatch after 18 days.

Pigeons are known for their monogamous mating behavior, where a male and a female form a pair bond. They engage in elaborate courtship rituals, including cooing, bowing, and mutual preening, to strengthen their bond. Once a pair has formed, they work together to build a nest. Pigeons are known for their resourcefulness and can create nests in a variety of locations, from tree branches to building ledges and even on window sills. They use twigs, leaves, and other available materials to construct a suitable nest.

After the nest is ready, the female pigeon will lay one or two eggs. The eggs are typically laid a day or two apart. Pigeon eggs are oval-shaped and vary in color, often appearing white or pale cream. The female will incubate the eggs to keep them warm and protect them from predators. Incubation is the process of keeping the eggs at a consistent temperature to allow the embryos to develop. Both the male and female take turns incubating the eggs, with shifts that can last several hours. This shared responsibility ensures that the eggs are constantly kept at an optimal temperature.

Pigeon eggs typically take about 17 to 19 days to hatch. The parents assist the chicks in breaking out of the eggs by gently pecking at the shells. Newly hatched pigeons, known as squabs, are small, featherless, and entirely dependent on their parents for food and warmth. Both the male and female pigeons play an active role in feeding and caring for their chicks. They produce a specialized secretion in their crop known as “pigeon milk,” which is regurgitated and fed to the squabs. Pigeon milk is rich in fat and protein, providing essential nutrients for the growing chicks.

Which bird can give milk?

Detailed Solution. The Correct Answer is Option 2 i.e Pigeon. Greater Flamingos, Pigeons, Emperor Penguins are the following birds have been known to produce milk. The best known of these secretions is the “crop milk” that pigeons feed to squabs.

Pigeons and doves are the primary bird species known for producing crop milk. This unique adaptation allows them to essential nutrients to their chicks during the early stages of development. Crop milk is produced by the parents, with both the male and female taking turns regurgitating it into the mouths of their chicks.

Before the eggs hatch, the walls of the adult pigeons’ crops become highly glandular. These glands secrete a nutritious, milky substance that is rich in fats and proteins. This crop milk is soft and easily digestible, making it an ideal food source for young birds.

Once the chicks hatch, the parents feed them crop milk for the first few days or weeks of their lives. This provision of crop milk is critical for the rapid growth and development of the young birds. It ensures that they receive the necessary nutrients to thrive during the early stages when they are most vulnerable.

As the chicks mature and their digestive systems develop, the parents gradually introduce solid food into their diet. This transition marks the shift from crop milk to a more varied diet of seeds and other food items. Crop milk is an extraordinary adaptation that enables pigeons and doves to nourishment to their chicks even in challenging environments.

Do any mammals lay eggs?

Most mammals do not lay eggs; however, there are five known extant species of mammal that do lay eggs. The five mammals which lay eggs are the platypus, the eastern long-beaked echidna, Sir David’s long-beaked echidna, the short-beaked echidna, and the western long-beaked echidna. The adorable platypus lays eggs.

The platypus is perhaps the most iconic monotreme. It is native to eastern Australia, including Tasmania. The platypus has a duckbill, webbed feet, and a sleek, waterproof coat. It is a semi-aquatic mammal, spending much of its time in the water. Female platypuses lay one to three eggs at a time. They incubate the eggs by curling their bodies around them and keeping them warm with their tail and body. After about ten days, the eggs hatch, and the mother nurses her young by secreting milk through mammary glands but without nipples.

Echidnas, also known as spiny anteaters, are found in various regions of Australia and New Guinea. Echidnas are covered in spines and have long, sticky tongues used to capture ants and termites, their primary food source. Female echidnas lay a single egg, which is incubated in a pouch-like structure created by folding skin around the egg. After hatching, the mother feeds her young by secreting milk through mammary glands onto specialized mammary patches on her belly, which the baby echidna licks.

The western long-beaked echidna species are found in New Guinea. These echidnas have longer snouts compared to the short-beaked echidna. Similar to the short-beaked echidna, female western long-beaked echidnas lay a single egg, which is incubated in a pouch-like structure. They also nurse their young through mammary gland secretions.

What is pigeon milk called?

It’s often called “crop milk,” because it comes from special cells in the bird’s crop. The crop is a section of the lower esophagus in some birds that is used for storing food before digestion. Unlike milk from mammals, pigeon milk doesn’t come from a mammary gland.

Before the eggs hatch, the adult pigeons undergo significant changes in their crop, a pouch-like structure in their throat. The crop walls become highly glandular and produce a thick, milky substance. This substance is rich in fats, proteins, and other nutrients essential for the growth and development of the chicks.

Once the eggs hatch, both the male and female pigeons take turns regurgitating this crop milk directly into the mouths of their chicks. This feeding process ensures that the young pigeons receive a constant supply of highly nutritious food during their early days when they are most vulnerable.

As the chicks mature, their digestive systems develop, and they gradually transition to consuming solid food. The parents facilitate this transition by incorporating seeds and other food items into their regurgitations, allowing the chicks to adapt to a more varied diet.

Pigeon milk is crucial for the initial growth and development of pigeon chicks. It a readily digestible source of energy and nutrients, helping the young birds to quickly gain weight and develop their feathers. Without this early nutrition boost, the survival rate of pigeon chicks would be significantly lower.

Is feeding pigeons harmful?

Pigeons may lead to various kinds of lung diseases, ranging from respiratory allergies to serious infections. The latter can lead to Pneumonia-Psittacosis, which is a bacterial infection and may result in death in 15 per cent of those affected by it if untreated.

Overpopulation: One of the most significant drawbacks of feeding pigeons is the potential for overpopulation. Pigeons are prolific breeders, and an abundant and easily accessible food source can lead to a rapid increase in their numbers. Overpopulation can lead to issues such as competition for resources and overcrowding.

Health Risks: Pigeons are known to carry diseases such as avian influenza, salmonella, and histoplasmosis. Close contact with pigeons, their droppings, or contaminated feed can pose health risks to humans, particularly those with compromised immune systems.

Environmental Impact: The excessive accumulation of pigeon droppings in urban areas can have negative environmental consequences. It can lead to aesthetic issues, property damage, and potential damage to historical or architectural structures.

Impact on Native Species: In some cases, the practice of feeding pigeons can lead to the displacement of native bird species and other wildlife. Pigeons, being opportunistic feeders, can outcompete other birds for resources.

Which bird gives egg and milk?

The female pigeon is the only species of bird that can produce milk and eggs, but no other birds are similar. Most birds have one parent who helps in raising the chicks before moving on to another nesting area. Crop milk is a secretion from the lining of the crop of parent birds that is regurgitated to young birds.

Pigeons and doves do not produce milk in the way mammals do. Instead, they create a specialized secretion known as “crop milk.” The crop is an expanded part of the esophagus in birds, and in pigeons and doves, it becomes highly glandular during the breeding season.

After hatching, the parents regurgitate this crop milk to feed their chicks. It is a crucial source of nutrition during the early stages of chick development. The parents take turns feeding the young, ensuring they receive a constant supply of this nutrient-rich substance.

As the chicks grow and develop, their digestive systems mature, and they gradually transition to consuming solid food. The parents facilitate this transition by introducing seeds and other food items into their regurgitations. Before the eggs hatch, the adult pigeons and doves produce crop milk by secreting a thick, nutritious fluid within their crop. This secretion is rich in fats, proteins, and other nutrients.


In pigeons are mammals has been definitively answered pigeons are not mammals; they are avian creatures belonging to the class Aves. This distinction becomes evident when we consider the fundamental characteristics that define mammals, such as being warm-blooded, having mammary glands, possessing fur or hair, and giving birth to live offspring. Pigeons, in contrast, are ectothermic, lack mammary glands, have feathers instead of fur or hair, and lay eggs. The exploration of this seemingly simple question about pigeons’ classification highlights the fascinating diversity of life on Earth. It underscores how different species have evolved distinct adaptations and characteristics to thrive in their respective environments. 

While pigeons and mammals may share our human habitats, they belong to separate branches on the tree of life, each with its own unique set of traits and evolutionary history. Pigeons, despite not being mammals, hold a special place in our world. They are highly adaptable birds that have successfully integrated themselves into our urban environments. Their coexistence with humans has led to a myriad of cultural, ecological, and even scientific connections. Pigeons have been revered as symbols of peace, studied for their remarkable navigational abilities, and observed for their complex social behaviors.

Moreover, pigeons serve as a reminder of the intricate web of life that surrounds us. Their presence, often taken for granted, plays a role in urban ecosystems by helping to control insect populations and serving as prey for urban predators like hawks and falcons. They have also contributed to scientific research on topics pigeon racing from animal behavior to genetics. Pigeons are indeed remarkable creatures in their own right, and their classification as birds serves as a testament to the diversity and wonder of the natural world. So, the next time you encounter a pigeon in your city, take a moment to marvel at the complexities of life that surround us, even in the most familiar of places.
