Seabird eggs in late spring and early summer are nutritionally substantial and would have been a valuable supplement to meat.

Fish — cod and other species abundant in the Gulf — could potentially be caught from the shore or in shallow water, though this would have required improvised tools and techniques.

And bears.

The accounts consistently mention bears as a food source, and bear meat is nutritionally valuable.

A large bear killed at the right time of year would also have provided a substantial hide for warmth.

The question of how Marguerite learned to exploit these resources effectively is not answered by the historical record.
