They have the characteristics of reptiles.though they have the reptilian characters it is more advanced then them.hence they are called 'glorified reptiles'.
It is not complete answer scientifically but Huxley has told that the million years ago the primitive reptiles like pseudosuchians has started a bipedal movement like birds after that during same time the Pterosaurs has developed a power of flight.During 150 million years ago the primitive bird Archeoptryx has formed the land bridge between the Reptiles and birds they shared the avian characters like feathers,fusion of skull bones like monocondyle like birds, opposed first toes of the foot,forelimbs modified wings,Soaring flight like modern birds.........

Birds are described as glorified reptiles because of their resemblance and relationship to prehistoric reptiles. Many theories in science believe that birds are descended from the dinosaurs.

Penguins are birds, not reptiles.
Birds are nor mamals or reptiles. They are it's own category,
mammals,birds,reptiles and amphibians.Any animal with its skeleton inside it.
The crinoid stalks and blastoid heads are the common fossils that best distinguish the classes of birds and reptiles. They classify birds to class aves and reptiles to the class reptilia.

Probably because they evolved from reptiles and have similarities to them, such as laying eggs on land. However there are many differences too, such as birds' having feathers and warm blood.
There are certain birds that eat reptiles.
No. Birds and reptiles are separate from amphibians.
Reptiles are cold-blooded and birds are warm-blooded.

No. They are birds.
Birds are reptiles. In 2004, a new cladistic classification of "Reptilia" came to include birds. Aside from their feathers, most birds are characteristically reptilian. Under their feathers are scales, they share similar organ and skeletal systems, and they lay eggs. The closes living relative of dinosaurs are birds. One of the earliest bird fossils shows evidence of a feathered animal with claws on the ends of its wings and a full set of teeth. Whether it was capable of flight is debated.
