Island Girl continued flying north, traveling 359 km (223 miles) on Saturday.
She was about 200 miles west of Churchill on Hudson Bay and roosted at approximately the same latitude.
The northern edge of the boreal forest dips south here and so she is now in the transition area between forest and tundra, or where the treeline ends. For the next four months, she will live, hunt, breed and raise her young in the northern tundra. No more trees until the fall migration.
She roosted at 997' elevation on a hill above Egenolf Lake, which hosts a hunting/fishing lodge.
Her track indicates that she is now veering NE, altering her bearing towards Baffin Island as expected.
