Swoopy Bird app for iPhone and iPad

A bird that resembles the Australian magpie swoops on bicycle riders. The player has to fly the bird over small and large trees and then let it swoop over and attack bicycle riders who are coming from the opposite direction. To stay in the game, the player must keep the bird flying by continuously tapping on the screen.
The most challenging part of the game is to keep the bird flying and letting it swoop at the right time so that it hits the head of the bike rider and does not hit the ground. If the bird hits a tree or the ground, he loses the game.
