Is A Parrot A Mammal?

Animal classifications can be challenging, and if you have ever wondered “is a parrot a mammal?” you are not alone; it can be a confusing topic, and if you don’t know all the defining characteristics of mammals, you probably won’t be able to work out the answer to this question.

Categorizing parrots isn’t necessarily easy, particularly because they share an intelligence level with some of the mammals that we know and love, and they make fantastic companions.

Birds are an interesting group, parrots are an interesting subgroup, and understanding what makes them belong to certain classifications and not others is a fascinating undertaking.

Often, the categories that we use to define animals are fuzzy and there are almost always exceptions, even where hard rules have been put into place, so don’t be too concerned if you can’t immediately tell what group a certain animal belongs to.

However, getting to grips with this can be useful for broadening your understanding of these birds, which is particularly helpful if you keep one as a pet.

Exploring the major characteristics of a parrot makes it easier to tell what category it falls into, and where it fits into the animal kingdom as a whole. Let’s look at some of their features and where this places them in the major categories that we use.

Is A Parrot A Mammal?

A parrot is not a mammal, and instead, it falls into the bird family, and more specifically into the aves class. The order Psittaciformes is the umbrella term under which all parrots come, and this places them distinctly out of the mammal category and in the avian one.

No animals are defined as both birds and mammals, although many of the characteristics of mammals are shared by birds, and vice versa.

To be categorized as a bird, a creature must be a feathered vertebrate, and it must have a bill; interestingly, the ability to sustain flight is not crucial for something to be categorized as a bird, although almost all parrots can sustain flight.

Parrots have curved bills, four toes on each foot, laterally placed eyes, and usually bright feathers. There are three subfamilies of parrots, known as Psittacoidea, Strigopoidea, and Cacatuoidea.

These three families carry quite different characteristics themselves, with the Psittacoidea being the “true parrot,” and containing about 350 different families. This includes Macaws, Budgies, and the African Grey, which are among the most famous parrots.

They are among the most colorful and intelligent of all parrots, which may be partly why they are the best known in most places. The three parrot families are spread across large parts of the world, including South America, Australia, India, and Mexico.

Why Is A Parrot Not Classed As A Mammal?

A parrot is not classed as a mammal because it does not have the key characteristics that are necessary to be a mammal, and instead it has the characteristics of a bird.

Scientists have therefore grouped the whole family of parrots into the bird section, as this is the most useful method of studying and categorizing them, and comparing them with other similar creatures.

Birds are one of the major animal groups, with many subcategories, and they make up a big percentage of the animals on this planet, with the other major groups being mammals, fish, amphibians, and reptiles.

Although parrots are not mammals, they are warm-blooded, which is often viewed as one of the biggest and most defining features of mammals – and this could be what causes some of the confusion about whether parrots are mammals, especially if you have ever been told that mammals are defined in this way.

All birds, unlike fish, reptiles, and amphibians, have warm blood, but they also have other characteristics that separate them from mammals.

It’s worth bearing in mind that these categories are ones that humans have developed to help themselves better deal with and understand these creatures.

Classifying a parrot as a mammal would be impractical from the perspective of science and trying to get a better understanding of these creatures, because there are major differences between birds and mammals.

It’s important to make these distinctions for the sake of studying and understanding both groups and the animals within them.

What Qualities Do Parrots Not Have That Define A Mammal?

Apart from being warm-blooded, parrots do not have any of the characteristics that make something a mammal, including hair, giving birth to live young, and the ability to produce milk.

These are generally seen as the main features of a mammal, although there are exceptions to this rule (for example, the platypus, which lays eggs instead of giving birth to live young).

Some people also classify mammals as having three bones in the middle ear, and parrots (along with all other birds) only have one, so they don’t meet this stipulation either.

Other people include high intelligence and particularly large brains in the list of a mammal’s key features, but this is more difficult to measure, and it’s certainly true that many parrots do have big, complex brains.

Overall, the parrot is missing the major things that a mammal has, particularly in terms of fur and the ability to produce milk and live babies.

A parrot’s feathers have not evolved from hair, as the fur of mammals has, and no parrots give birth to live young; they lay and incubate eggs.

When the babies are born, the female parrot does not produce milk to feed her young; instead, the parent birds will bring soft fruits and seeds to the baby.


A simple answer to the question “is a parrot a mammal?” is no, parrots are not mammals, and lack many of the key features that define an animal as a mammal. Although they are warm-blooded creatures, they do not share any other important characteristics, as they lay eggs rather than giving birth to live young, and they have no ability to produce milk. They also have no hair, having developed feathers for both warmth and flight instead.
