In this short article, we will answer the question “What do eagles eat?” and will show you why the eagle is so efficient in hunting their food.

What do eagles eat?

Most eagles eat other animals. They hunt species much larger than typical, weighing around 3 kg, and have been observed consuming rotting animals and small fish. They love to consume fish, birds, and medium-sized reptiles. 

Some bodies of water lack natural predators because of their enormous size and superior hunting abilities. 

A variety of predators, such as other birds of prey, including various types of eagles and hawks, bears, wolves, and cougars, can feast on eggs, hatchlings, young eagles, and injured animals.

Eagles are one of the top hunters in the animal kingdom because of their excellent eyesight.

Why is it that the eagle’s vision aids in its search for food?

Eagles require exceptional vision to be proficient hunters. As a result, their eyes have changed and adapted to offer talents that humans do not. The list that follows includes some of this bird’s most intriguing characteristics.

  1. Its eyes are nearly the size of a human’s.

Given that its eyes occupy the majority of its skull, this characteristic is rather visible. This does not imply that its functions are identical to those of a human organ, though. Despite this, the eagle’s remarkable evolution suggests that visual information is very vital to it.

  1. Their eyes don’t move

Being unable to move their eyes like humans is one of the effects of having such large eyes in such a small skull for eagles. Because of this, if they wish to look somewhere else, they must turn their entire heads and focus their eyes there.

  1. They have a simultaneous vision in both directions

Each eye of an eagle has two focal centres (fovea). It is because of these sites that light may enter and be processed for visual information. 

One of them, however, is responsible for looking at what is in front of him, and the other is responsible for looking at what is to the side. The bird can look in both directions at once even though its eyes cannot move.

  1. Recognize more colours than people do

The well-known cones, which are often divided into three types and sense the hues red, blue, and green, are one of the cells involved in colour perception. 

The eagle, however, possesses a fourth type of cone that can detect ultraviolet light. She can perceive more colours than people because of this. It also makes it easier for it to grab its victim by following its path.

  1. Eagles possess a third lid.

The golden eagle, like humans, has an upper and a lower eyelid, both of which serve to shield the eye from harm. The main drawback to this defence is that it temporarily renders the bird blind, which could be fatal. 

They created a translucent third eyelid (nictitating) as a defence against this, allowing them to see and shield their eyes simultaneously.

  1. Have excellent night vision

Being nocturnal, eagles frequently hunt during the day. Some species, though, have been observed foraging at night and in the dark. They have a lot of rods in their eyes, which gives them excellent night vision, therefore it’s not impossible.

  1. Its flexible neck allows it to see its prey better.

The golden eagle must turn its entire skull to look around because, as was already established, its eyes cannot move. Because of this, nature gave him a very flexible neck that makes it simple for him to rotate and adjust his eyesight.

  1. The visual acuity is 4 to 5 times greater than that of a human.

According to estimates, an eagle’s visual acuity can be four to five times stronger than a human’s. This is supported by three primary facts: birds have longer eyes, wider pupils, and more photoreceptors (rods and cones).

  1. The eagle has a faster processing speed for visual data per second.

The eagle is capable of 320 km/hr, which is a breakneck speed. Consequently, your eyesight must be able to handle a lot of data each second. 

This is made possible by the enormous number of rods in its eyes, which accelerate the flow of visual information and enable it to seek prey while it is in mid-flight.
