The White bird, or the "bomber bird" is one of the 8 (including mighty eagle) birds of angry birds, it is a tall whit bird with yellow cheeks and yells wee upon fire. the white birds ability is that when the screen is tapped is shall drop an explosive egg right below, the explosive egg will explode on impact and will send the bird hurtling upwards. the white bird itself can be used to hit a pig, but is much weaker than other birds at this, therefore the special ability comes in very handy! And can be very useful at times.

The white bird is first introduced in poached eggs 2-14, on the original angry birds,

Something strange however is that when the white bird drops it's egg, it seems to shrink and seems to look worn out like a popped balloon as it flies away.
