Witless Bay Ecological Reserve

Witless Bay Ecological Reserve is an ecological preserve close to St. John's, Newfoundland and Labrador, Canada. The Witless Bay Ecological Reserve consists of four islands: Gull Island, Green Island, Great Island, and Pee Pee Island. Immense numbers of birds nest on these islands during the seabird breeding season, roughly from 1 April through 1 September. The Witless Bay reserve contains North America´s largest Atlantic puffin colony. It is estimated that more than 260,000 pairs of Atlantic puffins nest there during the late spring and summer. The reserve also hosts the world's second-largest colony of Leach's storm-petrels. More than 620,000 pairs of these birds come here to nest every year. Thousands of black-legged kittiwakes and common murres arrive for the nesting season.

A tourism information centre is located in the reserve, by Lower Pond in the town of Witless Bay.
