Optical illusions are not only interesting, but also useful for the brain – they help us move from an automatic “labeling” of everything we see to a conscious assessment of what is happening around.
For example, if you look at this picture casually, it might seem like all the birds in it are parrots. But if you carefully study the drawing, it will become clear that pigeons hid among them.
How much exactly? It’s up to you to find out! Take a minute – if you don’t get distracted, this time is enough to carefully “scan” every square millimeter of the image.
Quiz: find all the pigeons in the photo!
