class Aves
Birds are categorised as the biological class Aves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the clade Theropoda.
Birds are not mammals, but avians. … They’re not mammals even though some species gather in flocks for foraging, hunting, childrearing, and protection the way mammals do in herds. Birds exclusively lay eggs. Some, like chickens, can even lay eggs without a male, but those eggs are infertile.
Reptiles are vertebrates that have scales on at least some part of their body, leathery or hard-shelled eggs, and share a number of other features. Snakes, lizards, turtles, crocodilians, and birds are reptiles.
Bird Classification
An animal is a land mammal other than a human being. Insects, birds and fish are not animals. Animals live in marine and terrestrial environments. Insects, birds, and fish are all animals.
Both birds and mammals are warm-blooded, which means they can maintain a constant body temperature and do not need to rely on an external heat source to stay warm. … Being warm-blooded also gives birds and mammals the unique ability to live on any landmass on Earth.
A Bird means a girl or woman who is promiscuous and stupid.
Reptiles have scales all over the body, whereas birds have scales on the legs and the rest of the skin is covered with fluffy feathers. … The forelimbs of birds are developed into wings, while most of the reptiles (7,900 species out of all the 8,000 species of reptiles) do not even have legs.
Peacocks can (sort of) fly – they tend to run and take several small leaps before a big final hop. They can’t stay airborne for very long, but their huge wingspan allows them to flutter quite far. 9. … Peacocks like to roost in high places, like roofs or trees.
They prefer to fly with a cloudless sky and favorable tailwinds. They can travel approximately 600 km (373 miles) in one night at about 50 to 60 kph (31-37 mph). When traveling during the day, the flamingos fly at high altitudes, possibly to avoid predation by eagles.
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.
The placenta seems to have evolved from the chorion, a thin membrane that lines the inside of eggshells and helps embryonic reptiles and birds draw oxygen.

Answer: (d) Birds and reptiles are uricotelic (not ureotelic) as they excrete nitrogenous waste uric acid in the form of pellet or paste with a minimum loss of water.
In the Linnaean system, organisms are grouped by characteristics regardless of their ancestry. So a reptile is an animal that is ectothermic and has scales, and birds would not be reptiles.
Parrots, eagles, penguins, chickens … they’re all dinosaurs. Birds are actually specialised coelurosaur theropods. Clearly, not all dinosaurs became extinct – over 10,000 species live among us today. One of the earliest known birds is the 150-million-year-old Archaeopteryx, but birds had evolved before then.
The kiwi is a unique and curious bird: it cannot fly, has loose, hair-like feathers, strong legs and no tail. Learn more about the kiwi, the national icon of New Zealand and unofficial national emblem.
However, penguins are classified as birds (Aves) in zoological terms. They are black and white flightless seabirds of the family Spheniscidae which are found in the southern hemisphere, chiefly in the Antarctic (although several species live in more temperate regions).
They have fascinating abilities that you should know about! Ducks are capable of changing their gender from female to male. This usually happens when a female loses one of her ovaries to infection.
