This model is an upgraded version of the traditional flapping bird, as the mother bird carries its hatchling. It is made with one double-sided paper, and each bird has a different color. This model requires previous knowledge in how to make a flapping bird, along with some experience in tessellations.
- 1 double-sided square piece of paper (It can be white with other color), of size 20x20cm (8x8 in). The finished model is about a quarter of the original, so it can be made with smaller or larger sizes. There is no strict type of paper but preferably a strong and light one.
- (Optional) Bone folder to the ones who feel comfortable with it.
