You are a pigeon and spring is coming. You need a bigger nest.
Fortunately there is a big tree. He lets some sticks fall on the road.
The goal is to take the sticks from the road and put them in your nest.
Unfortunately the road is full of fast cars and trucks but...
You can POOP on cars and trucks and make them stop.
To have your poop ready for launch you need to eat insects.
Use the Joystick in the upper left corner to move around and tap the right half of the screen to poop.
And one last thing: the veichles will crash the stick if they pass on it too much. Don't loose time.
Enjoy this natural nature game.
