Northern and Southern Giant Petrel

In this picture you see both giant petrels next to each other. The difference between the two species is really small. Both about the same 2 meters wingspan, both very variable in colour (so no, you can’t say Northern are white and Southern brown…). The only real difference is the colour of the bill tip: green in Southern, red in Northern. Fortunately they got a pretty big bill, so this tip is not that hard to see…
