In a study of kittiwake gulls, a coastline of cliffs 255 km long is divided into 100 m zones. Ten zones are chosen at random. These zones are censused, yielding 33, 48, 77, 0, 1, 0, 21, 5, 41, and 52 nests respectively. What is a good estimate for the abundance of adult gulls in this population?

Question

kropot72 · Answer

10 zones * 100m = 1 km of coastline censused.
Total nests in 1 km of coastline = 278 nests
Assume 2 adult gulls per nest.
Estimated total number of adult gulls in 255 km of coastline = 2 * 278 * 255 = ?
