Date of disappearance: 1832
Special power: The great bustard is believed to be the heaviest flying animal on earth (though there were once much bigger birds, such as the Argentine roc, Argentavis magnificens, which is believed to have weighed around 75kg and to have had a wingspan of about 8 metres). Despite their great weight, some populations are able to migrate for several hundred miles.
Status: The Great Bustard was reintroduced to Salisbury Plain in 2004. It seems to thrive on some arable land. It could be reintroduced elsewhere.
