what is the stranger looking for?

The stranger is looking for the elusive white heron. He collects birds; shooting and stuffing them. He has a vast collection but the rare white heron remains an unattained goal. He offers ten dollars to anyone who can locate the heron and direct him to its nest. Sylvia is initially excited by the mission, but realises that her bond with nature is stronger than that with the hunter, and she does not reveal the bird's hiding place.
