guano
Bat colony residue
Guano is the accumulated excrement of seabirds or bats, prized as fertilizer for its high nitrogen and phosphate content.
Massive deposits on Pacific islands fueled a nineteenth-century trade boom.
The word extends loosely to any animal droppings used as fertilizer: bat guano from caves.
