Tallest stork ever

The tallest stork of all time was the giant marabou stork Leptoptilos robustus, which stood 1.8 m tall, and weighed an estimated 16 kg. It was native to Indonesia's Flores island chain 20,000–50,000 years ago during the Pleistocene Epoch, and although it had well-formed wings its body and leg bones were so heavy that it may never have actually taken flight.
