Pretty much the same as the walkthrough.
1st bird through the pig in the top structure and sometimes to the pig in the crane (another type of bird!!!)
2nd bird through the bottom to the tnt and clearing the level

Even if you miss the crane pig, the tnt explosion might still get him. So, don’t quit, fire the second shot, and you might get lucky.

101980. Same as methods decribed, baloon and TNT threw debris up very violently, toppling the crane. Two birds left.

@Myselfiandme has the best strategy for high scores, but it takes a lot of attempts before the crane topples.

The next best strategy, to get consistents scores in the 93-95k region, is as follows:

First bird: aim for the wooden triangle on the crane. This will topple the crane and it’s worth spending one bird on just for points (unless you go for @Myselfiandme‘s much more difficult two-bird approach).

Second bird: as in video.

Third bird: little tower in middle.

Thanks for your strategy, worked liked a charm. Only 96K at the moment, but I am sure it will get better.

@f91jsw, that’s the same route I took and made out pretty good, that crane’s worth a lot of points together with the clawed pig when it falls over to the right.

The key to a high score two birdie is when and where to expand OB to throw up debris to knock off the right crane.
It’s pretty repeatable once you get it. I’ve got several 101K+, 103K+ scores and my current high of 105650.
First shot: Aim YB straight through the piggy in the little top left/middle structure. He will cut through and go on to get the dangling right piggy and break the piece of vertical wood blocking the bouncer. Here’s a screenshot:

http://angrybir.de/S6lRQT

This helps to expose the crane for your second shot.

Second shot: Is key to getting debris to fly up to topple the crane off the edge. You want to send OB horizontal through the bottom left bigger pig in the “roof”. Let him roll to the edge of the next roof and as soon as he lands at or slightly under the overhang of the slanted wood piece that makes up the left side of the second “roof”, manually expand him so that he ignites tnt and throws debris up to the right to knock crane off the edge. Here’s a screenshot of the trajectory:

http://angrybir.de/S6ppCv

In this screen shot I finished with 103330 but it’s the same trajectory I used when I got 105650.

Once you get the hang of the shot it becomes pretty repeatable. GL

Thanks AA @lesleyg for posting this alternate strategy. You do have a great “eye” for a better technique. Took me a while (stuck at 100, 103, and 104K but finally was able to aim my shots better.
Found that I could obtain 100k in score many times but to get higher than that, Yellow Bird had to take out most of the structure around the far right pig. It seemed to take less debris to push the crane up and get it to fall.
The Orange Bird was the challenge if for no other reason than all the debris and white clouds between the two slanted roofs. Finally notice that when OB is between the two lower edges of the slanted roof, there was more consistency in getting the debris to go to the upper right to hit the crane. If OB went any lower, to the stone blocks/tnt, I could not get the crane to fall.

Thanks AA. Your tip got me out of a rut. I finally started breaking the 100k barrier after reading. The key is not letting the OB drop to low before expanding.. Finally cracked the top 100. Thanks.

Thanks a lot for the strategy.

For the second shot I found out that inflating a little sooner is helping to get repeatable destruction of the crane.
Here is a screenshot: http://angrybir.de/19zQJQF

The cursor is pointing at the position where you should try to manually inflate the ob.

Of course you can’t see a thing when the bird is reaching this point so it’s guesswork ;-)

Here is the destruction I got for my highest score: http://angrybir.de/I1mI6B

Used strategy by @lesleyg for 112k. This level is changed, the cranes topples more easily now. I also get a few more k when a big part of the crane toppled left instead of right, doing more damage below.

I am adding this level to my growing list:

@Kathy you should a break from the advent challenge and hit this one again real quick. you should be able to pick up an easy 10K or so. YB through the pig up top and pig in a claw. OB slightly above horizontal. through the wood and into the gap, expand near the ground. one in 5 times a stone has been knocking the crane over. 5 scores over 107 in 5 min, of course the first was the best at 111.

Well this is not going to be much help. Just got the top score for this level but not really sure of the detail of how it happened. I shot yellow bird through the green Pig in the house and it cut through the cable holding up the Pig in the claw. I then sent OB through the towards the TNT with the aim of manually expanding in the gap above the yellow spanner. What happened next I did not see, as the screen moved back to the left as if to prepare for launch of third bird. All I saw was the counter then start to climb and keep climbing until the high score was shown. I could not see what the destruction looked like, but can only assume the crane had been tilted to the right and destroyed itself. I did get a screenshot of the high score though and will look to post that as proof If I can work out how.

Just got the puppy after only about 5 minutes of play, proving level is much easier. Used same method described above by @lesleyg and others. First bird through the pig on top, continuing to get the hanging pig.next one through the larger pig on the left expanding when it gets to the level of the tnt.

I used the strategy posted by @lesleyg and visualized by @comex666. His video pretty much says it all. A few thousand extra points can be gained when OB deflates to the right to push you over the treshold.
