Real in Life Angry Birds

Red – The red bird is your most basic strike of attack.
Blue – The blue bird will break into three smaller  birds when the screen is touched. These birds are useful for taking out glass structures and when used correctly will completely destroy it, causing a lot of damage for those stinking filthy pigs.
Yellow – The yellow bird has the advantage in long distances and you need only tap the screen for  a power boost. 
White – The white birds are bi-effective. If you tap the screen in flight is causes the bird to drop a large explosive egg, your original bird still flies forward. This means that can drop the egg on the lower structure and the bird will still strike the upper portion of the structure.
Black – Black birds are the essentially just canons  and can be used to topple the structure but will also explode. Launch this bird at a steep angle and it could bust the bottom of large structures.
Green – The green bird is similar to a boomerang bird, but with time you find so many more uses. You can use the bird to launch straight into a structure and deal intense damage.
