4 Know your birds. As you progress, you'll notice that there are different kinds of birds and they create different results when tapped. (You have to launch the birds first before tapping.) Here is what each bird does:

• Red bird: The most ordinary bird; it doesn't have any special effects other than being able to be catapulted into the pigs. In the Red's Mighty Feathers update, his new power is when you tap somewhere on the screen, he goes to that place.
• Blue bird: Tap the screen and it becomes three mini birds. This bird is best for breaking glass.
• Yellow bird: Tap the screen and it goes very fast. This bird works best on wood.
• Black bird: Tap the screen and it explodes instantly. Let it hit an obstacle and after a short time delay it will explode. This bird works best on stone. In the Short Fuse update, instead of exploding, he sends out a very deadly shockwave that electrocutes pigs nearby.
• White bird: Tap the screen and it will drop an explosive egg. The corpse, if done right, will fly off and potentially cause additional damage. This bird also works best on stone.
• Green bird: Tap the screen and it will fly back. This bird is similar to a boomerang.
• Big Brother bird: Similar to the red bird, but bigger in size and more powerful.
• Orange Bird: Very small, but swells up to big proportions. Try to squeeze it into tight spaces.
• Pink Bird: Small, but levitates objects with bubbles. Use her to disrupt the bottoms of tall towers.
• Mighty eagle: Press the button at the top of the screen and a sardine can appears. Launch the sardines and the mighty eagle will appear. You have to pay for this feature and once you use it on an unsolved level you have to wait another hour before using it on the next level. You will not get any stars for using this bird.
