The small red bird is the bird you start out with on Angry Birds. They have no special powers (but do squawk if tapped).
The small blue birds are "Scattershot" birds and dissipate into three small projectiles when the screen is tapped.
Yellow birds are "Kamikaze birds" and rocket at super speeds when the screen is tapped.
Black birds are bombs that explode to create shock waves and destroy close objects. They blow up in their own time, but if you tap you can explode them instantly.
White birds are egg droppers. Tap the screen to launch an explosive egg from your backside, before firing your now deflated friend into the stratosphere.
Green birds turn around and fly backwards at roughly double the speed when the screen is tapped.
The large red bird has the destructive power of the black bomb bird, just without the explosive finale. His giant size makes it tough to squeeze into tight corners, but he can wipe out entire structures just by wiping out the bottom foundations.

Angry Birds is a video game franchise created by Finnish computer game developer Rovio Entertainment. Inspired primarily by a sketch of stylized wingless birds, the first game was first released for Apple's iOS in December 2009. Since that time, over 12 million copies of the game have been purchased from Apple's App Store,] which has prompted the company to design versions for other touchscreen-based smartphones, such as those using the Android operating system, among others.
