The first thing you hear when you step foot onto the island from those already there isn't "Hello," or "Welcome," or "How was the trip?" It's "Watch the nests!" because the nests are *everywhere*. Anywhere there's no more vegetation than sparse grass, there are nests. On rocks, on dirt, on concrete. Every single step you take on the island must be done with head down, watching your feet. You're here to support this nesting colony, not stomp it to pieces.
