The narrow edge: a tiny bird, an ancient crab, & an epic journey

Beginnings

The "uttermost part of the earth" : Tierra del Fuego

When is the beginning of the end?

The urban bird and the resort : Río Gallegos and Las Grutas

Bay of plenty : Delaware Bay

Tenacity

Blue bloods

Counting

Lowcountry : South Carolina and other tidelands

Ghost trail : the Laguna Madre and the central flyway

Does losing one more bird matter?

The longest day : the Arctic

Returning south : James Bay, the Mingan Islands, and the Guianas

Heading home.
