Premise: Little Jost Van Dyke (colloquially, "Little Jost") is one of the British Virgin Islands. It is a small island on the east end of the island of Jost Van Dyke. Like Jost Van Dyke, it takes its name from the Dutch privateer Joost van Dyk. It is the location of the Diamond Cay National Park, which includes the nesting grounds of wild boobies, terns and pelicans.
Hypothesis: Boobies, terns and pelicans are not territorial on Diamond Cay.
