HEY BUDDY HERE IS UR ANSWER !!!

Birds, also known as Aves or avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.

Birds, also known as Aves or avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.Birds have wings which are more or less developed depending on the species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in flightless birds, including ratites, penguins, and diverse endemic island species of birds. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming.

Answer 2

HEY USER ,

HERE IS YOUR ANSWER :-

MODERN BIRDS ARE TOOTHLESS : THEY HAVE BEAKED JAWS . THEY LAY HARD - SHELLED EGGS . THEY HAVE A HIGH METABOLIC RATE A FOUR - CHAMBERED HEART , AND A STRONG YET LIGHTWEIGHT SKELETON .

BIRDS LIVE ALL OVER TO WORLD . THEY RANGE IN SIZE FROM THE 5Cm (2inch) BEE HUMMINGBIRD TO THE 2.70metre (9ft.) OSTRICH . THEY HAVE A CLASS OF TETRAPODS THE MOST LIVING SPECIES : ABOUT TEN THOUSAND .

MORE THAN HALF OF THESE ARE PASSERINES , SOMETIMES KNOWN AS PERCHING BIRDS.

BIRDS ARE THE CLOSEST LIVING RELATIVES OF THE CROCODILIA . THE FOSSIL RECORD SHOWS THAT BIRDS EVOLVED FROM FEATHERED THETOPOD DINASOURS .

BIRDS HAVE WINGS ARE MORE OR LESS DEVELOPED DEPENDING ON THE DPECIES . THE ONLY KNOWN GROUP WITHOUT WINGS ATE EXTINCT MOA AND ELEPHANT BIRDS . WINGS WHICH EVOLVED FROM FORELIMBS , GAVE BIRDS THE ABILITY TO FLY .

BUT DUE TO MANY REASONS MANY BIRDS ARE EXTINCTING AND SOME ARE ENDANGERED . WE NEED TO MAKE EFFORTS TO SAVE BIRDS .

HOpE IT HELPS YOU ❣️
