Closer view of a particularly dense part of the colony.
観察結果の詳細
Estimate of numbers arrived at by taking what the expedition guides said was the maximum extent of the colony in a good year and estimating what percentage of that area was filled with birds. Many large young birds present, especially on the lower portions of the colony and near the beach, where they were gathered in large creches. At the beach themselves many hundreds of adults were arriving and departing in the surf. The upper reaches of the colony still had some very young birds being tended by adults, but these were a small minority of the colony.
