What is recorded here

Colt Island is the smallest of three low-lying, uninhabited islands off Skerries in County Dublin, Ireland. It sits half a kilometre from the mainland, dressed in grasses, brambles and hogweed, while seabirds breed there and water fowl overwinter. The Irish name Inis Coilt may point to a food source, though that remains a proposal rather than a fact. A person standing on the Skerries headland would see little more than a dark smudge above the tide, yet that smudge holds life in numbers the mainland cannot match.
