Flight-by-Fowl

Falbi’s Flight by Fowl is a minigame run by Falbi that is found in Twilight Princess. The idea is to pick a Cucco and then jump of a ledge located high above Lake Hylia. By guiding the rooster through different targets, Link will gain Rupees. If he can land on a platform located on the lake itself, he will also earn bonus Rupees. The locations of various Prizes are:

Poes:
 * On the main island. Wait until night
 * On the small ledge under Falbi's Hut. There is also a secret cavern with some Shell Blades in it here, too

Pieces of Heart:
 * Under the spinning platform on the main isle is a minuscule ledge. Link needs to carefully drop on to it to claim the Heart Piece

Rupees:

Orange (100):
 * On the spinning platform on the Main isle
 * On one of the serpent heads outside the Lanayru spirit cave (Clawshot Recommended)
 * Defeat all the Shell Blades in the secret cavern

Purple (50): It is part of the Fyer and Falbi Hylia Fun Center.
 * On the ledge right below the Heart Piece on the main isle
 * On one of the serpent heads outside the Lanayru spirit cave (Clawshot Recommended)

Secrets
When you use Fyer's Cannon to get up to the hut, get out your Gale Boomerang when you land, and look for a wind switch on the roof. Aim the boomerang at the switch, and the platform on the island will stop spinning.

Getting the Piece of Heart is far easier if a direct path to it is taken instead of following the Rupee trail.
