Hyrule Compendium Entry
The Swallow Bow can be found mostly in Rito Village, but some are scattered around Tabantha Frontier and the Hebra Mountains. In Rito Village, Harth can fix the Great Eagle Bow with 5 Bundles of Wood, a Diamond, and a Swallow Bow. In the same room that Harth is in, a Swallow Bow can be found on the table next to Harth. If Link takes it, Harth will start to scold him, but then realize he doesn't need it and lets Link take it.
