Which is the largest bird?

                    The largest living bird is the ostrich. It stands up to 2.5 m high and weighs 135 kg. Two extinct birds, the moa of New Zealand and the elephant bird of Madagascar, stood about 3 m high and would dwarf even the ostrich. The largest living bird capable of flight is the albatross, which has a wing span of 3.5 m. However, the largest-known flying bird lived about 2 million years ago. It was a condor-like bird with a 5 m wing span.
