Is bird a reptile or a mammal?

Thanks for subscribing! Birds are not mammals, but avians. Unlike mammals, they do not have fur or hair — instead, they have feathers, though sometimes they possess bristles on their heads or faces that resemble hair.

Are birds not reptiles?

According to the phylogenetic classification system, a reptile is any animal which originated from the original group of reptiles, technically including birds and mammals. Therefore, birds are considered reptiles under Phylogenetic taxonomy, just as other animals that descended from vertebrates are called vertebrates.

What animal class is a bird?

ReptilesBirds / Class

What is a bird if not a mammal?

A member of the Aves class (i.e. a bird) has the following basic characteristics that are not shared by mammals: Feathers: birds’ bodies are covered by a number of different types of feathers. Feathers help with flight, and also with insulation (keeping the bird warm).

Are birds closely related to mammals or reptiles?

Answers Mammals. Birds aren’t just closely related to dinosaurs, they are really are dinosaurs this is what most people mean when they say that birds are reptiles, although technically according to the phylogenetic system mammals are also reptiles.

What is the difference between birds and reptiles?

The main differences between modern birds and modern reptiles are: Birds have feathers over most of their body while reptiles have scales. Birds have warm (temperature controlled) blood, while reptiles rely on external heat sources to warm their blood. Birds have very light hollow bones, making them much lighter than the equivalent reptiles.

Did birds evolve from reptiles?

Birds are much more closely related to crocodiles than crocodiles are to turtles or to lizards. And birds didn’t evolve from any of the types of animals we call ‘reptiles’ today. If we go by the phylogenetic tree and insist on calling animals reptiles, though – then birds actually ARE reptiles.

Are birds technically reptiles?

Birds are technically reptiles, but they’re evolved to the point where they’re essentially their own group. Birds are the last remaining lineage of dinosaurs, and have scales. The dinosaurs were also partly feathered and semi-warm blooded, as well as egg layers. So, they could definitely be considered a subtype of reptiles.
