Migratory birds
Placed beside human wayfinding because both use the night to go somewhere. The bird's method is a biological mechanism. Mau Piailug's method is a learned practice with a teacher. Those are different kinds of knowing.

Observed
- Many night-migrating songbirds orient using both a magnetic compass and celestial cues.
- Stephen Emlen's planetarium experiments in the 1960s showed that indigo buntings can learn star patterns for orientation.
- Work by Wolfgang and Roswitha Wiltschko established a magnetic compass in birds, later connected to light-dependent magnetoreception.

Interpretation
The interesting rhyme is function: a body finding a direction from field and sky. The mechanism is not shared with canoes, gospels, or epics. Biology is not a metaphor for navigation until we say so, and even then it remains biology.
Mechanism
Known biological. Magnetic and stellar compasses in birds are experimental findings. Details of the receptor are still researched. The existence of orientation, not a complete molecular story, is what holds here.
Open questions
How much of a bird's map is inherited, and how much is learned from a sky?
What is lost when we call both a bird and a navigator 'oriented' as if the word were one tool?
