Readers with very sharp eyes can distinguish three distinct features in just eleven seconds when comparing the bird images.
One of the most common ways to keep people's interest on the internet nowadays is with a Find the Difference puzzle, which is also called a spot-the-difference puzzle.
The objective of this challenge is to have readers find the differences between two nearly identical photos.
In order to find solutions to these problems fast, meticulous attention to detail is required.
Regular practise of such challenges can have positive effects on mental health and focus in people of all ages.
In under eleven seconds, readers must identify three key changes between the two images.
It may take some focused observation to make out some of the distinctions, while others may stand out immediately.
