This is the smallest of all the Alberta protected sites at less than an acre. An island in Lake Athabasca, it protects a nesting site for Caspian Terns.

Other Information
Egg Island Ecological Reserve, located on Lake Athabasca, was established to protect a major breeding colony of Caspian Terns, a “vulnerable species”. The terns are believed to have nested on this island since the early 1900s. They usually nest near the centre of the island with large numbers of California gulls. The island is nearly devoid of vegetation on the windward side; on the leeward side, raspberry, gooseberries, and the occasional willow, balsam poplar, and aspen are found.
No access is permitted within 100 metres of the island during the bird breeding season from April 15 to August 15 [1].
Terns of Reference. The regal Caspian Tern is the largest tern in the world, easily recognized by its brilliant red fish-knife of a bill and deep, raspy call. Found all over the world, the Caspian favors both freshwater and saltwater environments. It feeds mostly on fish, captured in nimble aerial dives. On the nesting grounds, paired Caspian Terns perform splendid displays in the air, rising up to great heights in tandem. They migrate nocturnally and, in autumn, their rolling calls are sometimes heard overhead during the night [2].
