The definition of a bird
requires feathers, a toothless beak, wings (usually allowing for flight), and the ability to lay hard-shelled eggs. Meanwhile, mammals
have hair, give birth to live young, and the females produce milk from mammary glands — the structures for which the class is named.

You may have more in common with a pigeon than you realise, according to new research. It shows that humans and birds have brains that are wired in a similar way. Yet, birds have been shown to be remarkably intelligent in a similar way to mammals such as humans and monkeys. ...
Whereas birds have feathers, lack teeth and lay eggs, mammals have fur or hair for insulation, possess teeth and give birth to live young. Although birds are more closely related to reptiles than mammals, birds and mammals have several characteristics in common.
The last common ancestor of birds and mammals (the clade Amniotes ) lived about 310 – 330 million years ago, so 600 million years of evolutionary time in all separates humans from Aves , 300 million years from this common ancestor to humans, plus 300 million years from this ancestor to birds.
New research suggests that some birds may know who their human friends are, as they are able to recognize people's faces and differentiate between human voices. Being able to identify a friend or potential foe could be key to the bird's ability to survive.
We'll start with the "reptilian" similarities of birds. Like all other reptiles, birds have scales (feathers are produced by tissues similar to those that produce scales, and birds have scales on their feet). Also, birds lay eggs like other reptiles.
Amphibians are similar to birds in several ways, with the most fundamental similarity being that both are living things made of eukaryotic cells....
Although birds and bats have the same types of bones in their wings, the bones in a bat's wing more closely resemble those in a human hand. With more than two dozen joints in their wings, bats can exercise a great deal of control over the three-dimensional shape their wings take.
They all have feathers, wings, and a beak, which means they are all birds. Birds share many characteristics with reptiles. Like reptiles, birds are vertebrates.
Physical features lightweight, smooth feathers – this reduces the forces of weight and drag. a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight. an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust.
Penguins are carnivores; they eat only meat. Their diet includes krill (tiny crustaceans), squid and fish. Some species of penguin can make a large dent in an area's food supply.
And while there are some incredible similarities, chickens are neither a mammal or a reptile. They are a part of the fowl family; a branch of species all its own.

The "shoulderblade" of the human is actually a bone called the scapula, birds have a scapula and they also have an additional shoulder blade bone called the corocoid. Another obvious difference between the human and bird skeleton is the shape and size of the sternum.
Humans are one type of several living species of great apes. Humans evolved alongside orangutans, chimpanzees, bonobos, and gorillas. All of these share a common ancestor before about 7 million years ago. Learn more about apes.
They are all mammals. Humans and birds are a different matter. Yet they, too, share a lot of DNA -- 65 percent.
The mammalian lung has reciprocating ventilation with large terminal air spaces (alveoli) while the avian lung has a flow-through system with small air capillaries. As a result the environment of the pulmonary capillaries is very different between the mammals and birds.
But it turns out that birds have evolved a different but quite remarkable system for generating sophisticated, flexible thinking, right alongside ours. Both bird brains and human brains [are asked] to meet some of the same challenges in nature and solve some of the same problems, both ecological and social.
He said he was aware of a good study from 2012 that suggested that bird brains respond to song in the same areas that human brains do. “As a shorthand way of thinking, if a bird song sounds musical to human ears, odds are that similar human music will sound songlike to the bird,” Dr. DeVoogd said.
