Ostriches are one of the most unique and fascinating birds on Earth, with a number of features that set them apart from other avian species. Belonging to the group Struthioniformes, these large flightless birds are known for their towering heights, which can reach up to 2.8 meters tall. In addition to their impressive size, ostriches also hold several records on Earth for being the fastest group of flightless birds.
One of the most remarkable features of ostriches is their eyes. These bird’s eyes are the largest of any land animal, measuring about 5 cm in diameter – five times larger than human eyes and even larger than their own brains. The shape and size of ostrich eyes have evolved uniquely compared to other bird species, despite being large, they are similar in shape to those of other birds like green starlings and tawny owls. Experts believe that the evolution of ostrich eyes may have been influenced by their weight, as they do not face the same restrictions as birds that need to fly efficiently.
While ostriches have impressive vision capabilities, they also have significant blind spots on the top and back of their heads. This adaptation helps protect their eyes from damage under the intense tropical sun. Ostriches have binocular vision in front of their beak, which aids them in finding food on the ground. Their visual field extends vertically to 80 degrees and widthwise to 20 degrees, allowing them to focus on small objects like grass, seeds, and insects.
