How to trigger the bird’s special abilities using Apple Magic Trackpad

Here's a guide on how to get all the golden eggs. This is copy and pasted straight from the website:

• Getting 3 stars in the first chapter
• Getting 3 stars in the second chapter
• In the level select screen, tap the sun
• Watch the credits, there's one at the end
• Within any level, go to the help screen. There's one in the white bird's help image.
• Level 1-8, tap the unreachable chest
• Level 2-2, break the beach ball
• Level 4-7, at the very top right of the map (zoom out)
• Level 5-19, it's hiding on the top right of the left tower

There are a number of stages where you can exceed the three stars score by a healthy margin. Most of the time, if you used all of your available birds and still got three stars, you can improve your score by completing the level with fewer birds. Obviously, it's going to be difficult to improve some of your scores, but even adding 10 or 20 points to some of the levels will help.
