On her third day of migration (21 September) , Island Girl took a sharp turn west across the tundra towards Hudson Bay, a route she knows well.
She flew an impressive 642 km (399 miles) for the day and reached her destination on Johnson Island, located well out into the southeastern part of the bay.
Johnson Island is one of the northernmost of the Belcher Island group and we have often had peregrines roost in this archipelago during both spring and fall migrations.
She roosted on the ground on a rocky slope above a small salt-water bay at about 55 feet elevation. Looks like a good hunting perch too.
