Melvin's final report from the field, South Georgia: "On Salisbury plains. Most dense part but less than 10% of the rookery. It has 60,000  breeding pairs as well as fur seals, sea lions and predatory birds.

"Leaving South Georgia today to avoid large storm and high waves. Given internet limitations, I'll try to send individual pictures as we make our way north and then west towards Argentina. Take care."

Where is South Georgia? Way south of Atlanta, for sure:

Southeast of Argentina--there's a phrase I've never used before on this blog.
