Site description Placentia Bay is located in southeast Newfoundland between the Avalon and Burin peninsulas. The IBA includes the eastern half of Placentia Bay from Argentia to Cape St. Marys and out to 25 km from shore. There are several low, non-vegetated isolated rocky islets in Placentia Bay. The Virgin Rocks, located 3 km west of Great Barasway are included in the site.

The bay is usually ice-free year round and prevailing southwest winds in summer produce frequent fog banks. Caplin spawn in the shallow waters of Placentia Bay; spawning season is anytime in June and July. The spawning caplin in this area attract large numbers of seabirds and Humpback Whales close to shore.
