Strengths and Weaknesses

All birds have their own strengths and weaknesses with their ability to cut through materials. Here is a list of all the birds with their strength and weakness materials.

Red Bird
Strength: The Red Bird has average strength on all materials and can shatter one piece of glass or wood without problem.

Weakness: They become weaker as the player discovers the structures become more complex. It is weak against stone and can only break it if the stone block is almost destroyed.

Blue Bird
Strength: They ironically have a great strength against glass, as they can shatter a max of three thick walls of it (with an individual bird).

Weakness: The Blue Bird is the weakest of the birds and is useless against many structures. They don't cause a lot of damage to wood, and they are useless against stone, unless if they are used to topple it over so it capsizes a weaker structure.

Yellow Bird
Strength: The Yellow Birds are as strong as the Red Bird, but their force is increased when they speed up. They can shatter up to five walls of wood (three if not sped up).

Weakness: Yellow birds are not as effective against square blocks. They don't cause a lot of damage to stone (even if sped up) and it would take three (two if sped up) birds to shatter a block of stone. They can also destroy glass, but their speed and strength will horribly decrease.

Black Bird
Strength: The Black Birds are one of the strongest birds when they face stone, as they can shatter a max of four blocks before blowing up. When they blow up, the explosion can destroy almost every material in a small blast radius. Any material hit by the larger forcing radius surrounding the blast radius will be pushed and damaged. They are average on other materials.

Weakness: Black Birds will not be very effective against a structure made of densely packed small square blocks made of different materials.

White Bird
Strength: The eggs they deploy deal great damage to glass and wood and medium damage to stone. The Bird itself when corpsed after launching the egg can cause additional damage to structures.

Weakness: Although the eggs deal good damage, they suffer a small blast radius. Also, the bird itself before launching the egg deals poor damage.

Boomerang Bird
Strength: The Boomerang Bird has slightly more strength than the Red Bird. It is excellent against wood and glass. It also flies farther than the rest of the birds.

Weakness: It deals minimal damage to stone. Also, making its arc is a little hard, lasting too much to make the bird turn, will make the green-feathered bird to crash into the ground and becoming a corpse.

Big Brother Bird
Strength: It is strong against any material. It will almost always destroy if not the whole structure, then a large portion of it.

Weakness: Its large size prevents it from going into small spaces or avoiding obstacles. It also flies a shorter distance due to its weight. And he is weaker the further the distance you aim with him (sometimes a piece of wooden block is enough to stop him and turn him into a corpse in a long shot)

Orange Bird
Strength: The Orange Birds have medium strength against everything head-on, but they are most lethal when blown up. When blown up, they don't do much damage unless they are in a cramped area. They can push and damage any material they hit when they inflate.

Weakness: It sometimes merely pushes material rather than damaging them.

Lazer Bird
Strength: He has the same strengths as his normal form, but with little changes. First, the player can lock-on on which place of the structure the Lazer Bird has to impact. Second, he accelerates a bit from the start, and even more when he locks-on his target.

Weakness: He also has the same weakness of his normal form, with some added. When he locks-on, sometimes thngs can get in the way, as asteroids, and more when the player is on a boss level. Also, if the target locked is a moving one, the bird can't follow it.

Ice Bird
Strength: Turns all blocks to ice. Also can detonate TNT by freezing. Very useful if the next bird after him is the Blue Bird (because the Ice Bird is more of a support oriented bird rather than damage oriented, and because the blocks are turned to ice and the Blue Birds are strong against this material).

Weakness: Does minimal damage to blocks on its own. Nearly impossible to clear levels its own.

Mighty Eagle
Strength: Destroys any material on its path.

Weakness: None.

Sardines
Strength: Summon the Mighty Eagle.

Weakness: Does minimal damage to blocks on its own.

Mighty Dragon
Strength: Like the Mighty Eagle, it destroys all Pigs on the stage.

Weakness: It flies in a loop and mostly misses the bulk of material, making it harder to achieve 100% total destruction.

Red Koi Fish
Same as the Sardines.

Space Eagle
Strength: Similar to the Mighty Eagle, but emerges from a wormhole in lieu of a swooping motion.

Weakness: Does not necessarily clear all pigs.
