Scientists p-p-pick out penguins from space for new head count

Emperor penguins, lots and lots of them – and now we know just how many. Antarctica contains more than half a million – nearly double the number previously thought, a satellite survey has revealed. In the first comprehensive census of a species taken from space, high-resolution photos of 44 colonies around the Antarctic continent showed there were 595,000 birds – the previous estimate was 350,000.
