Penguin Plenty?

After a number of stories about the population pressures to which a variety of penguin (especially Emperors- https://www.theguardian.com/environment/2014/jun/29/emperor-penguins-at-risk-of-extinction-scientists-warn) species are being subjected by climate change and over-fishing, it is somewhat heartening to read that unexpected, breeding 'mega-populations' of about 1.5 million Adelie penguins have been detected in the Antarctic (https://www.theguardian.com/environment/2018/mar/02/mega-colonies-of-15-million-penguins-discovered-in-antarctica). The birds have been recorded using drones and are utilising the, rarely visited, Danger islands in the Weddell sea. Of course, we could still be in a position to lose some of the bigger species of these birds.
