This is a fairly basic origami project. I followed the animated instructions from the British Origami Society.
It's a simple project that starts with a bird base and adds a couple extra slight creases to make the bird flap his wings when you pull his tail.
Just for fun today.
The bonus: a crane. This one made without a pattern, just some basic origami I've learned over the past couple of weeks, and the crane that hangs over my desk as a model.
