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.
