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 Birds 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 Bird is strong as the Red Bird, but his force is increased when he speeds up. He can shatter up to five walls of wood (three if not sped up).

Weakness: Yellow Bird is 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. He can also destroy glass, but his speed and strength will horribly decrease.

Black Bird
Strength: The Bomber is one of the strongest birds when he faces stone, as he can shatter a max of four blocks before blowing up. When he blows 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. He is average on other materials.

Weakness: Black Bird's ability is timed, making it harder for the player to get it in the right place for maximum destruction. He's also weak against snow, clouds and sand, despite they're the weakest materials on the game, as they slowly stop the Black Bird's movement. The more snow/cloud/sand blocks shattered, the more Black Birds are stopped.

White Bird
Strength: The eggs he 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. He is excellent against wood and glass. He also flies farther than the rest of the birds.

Weakness: He 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: He is strong against any material. He will almost always destroy if not the whole structure, then a large portion of it.

Weakness: His large size prevents him from going into small spaces or avoiding obstacles. He also flies a shorter distance due to His 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 Bird have medium strength against everything head-on, but he is most lethal when blown up. When blown up, he doesn't do much damage unless he is in a cramped area. He can push and damage any material He hits when he inflates.

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

Blu and Jewel
Strength: Does great damage to wood, their strength is same as the Yellow Bird as they does great damage to wood. They also can damage glass.

Weakness: They are maybe powerful against wood and glass, but they are not great against stone and only can break one block of stone. Also, if you fling they high and you want to damage lower structure, they will keep fly straight at the up when you tap the screen and misses the lower structure.

Blu
Strength: He does great damage to wood and glass, even destroy it when he was shaking himself.

Weakness: The only structure he can't face is stone. He only deals minimal damage with it, and sometimes he merely pushes stones rather than damaging it.

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 Laser 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 things 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.
