The proposition in your question is not correct.Admittedly, it seems so because the owl has a flatter face than the eagle. This makes the eyes really visible in the same plane.
The face of an eagle is Spitser, the eyes lie further from each other and thereby less in the same plane than that of an owl.But because the eyes are bulging, the eagle can still look straight ahead and enjoy all the benefits of stereoscopy.
Owls have eyes that are so large that they are a little clamp and then they are also attached to the skull with cartilaginous plates.
All in all, they can barely move their eyes.This also helps them to hunt well, because those star-facing eyes ensure that owls can accurately estimate the distance to prey. And because of the size of the eyes, there is no mouse unseen at dusk.
Many owls have a circle of feathers around their eyes, the 芒 鈧?虄sluier芒 鈧劉.But, these stiff, particularly shaped feathers have a completely different function. They ensure that sound is amplified up to 10 x and led to the ears. Owl ears are also holes on the side of the head, hiding under the feathers of that veil. Which makes it seem even more special that the eyes are facing forward.
In general, predators have eyes at the front and prey the eyes on the side.
With eyes on the front you can see good depth without moving what is beneficial for sneaking prey. With eyes on the side you can see everything without always having to look.
Owls have very big eyes.Because of the placement they can see very well depth, even at a larger distance. The eyes are not round bulbs like with us. They are more oval, stretched lengthwise. This will not allow them to rotate the eyes. They therefore rotate the whole head, almost 360 degrees. By moving the head sideways back and forth, they can even better estimate the distance to a prey.
Owls are mainly nocturnal creatures, hence those big eyes.During the day the light is too bright for them. Other birds of prey (fenders) hunt especially at day. That puts very different demands on the eyes.
That has to do with the way they hunt and that is then determined by the lifestyle, food and the area where they live.
Owls hunt when their prey are awake.Mice and rabbits are active in twilight light because they feel safer. If your protection is mainly made of bracts then the Twilight light is useful for less to stand out. Owls have adapted to this, their eyes (more specifically the iris) have become larger to absorb more light. The eyes are also directed towards the front so that they get a better focus in a narrower viewing area. Hence their advantage of a good vision in low light and the ability to fly almost silently thanks to their special wings. Something that comes in handy when you hunt in dense forests and rocky regions.
Raptors especially need a sharp view high in the air.Then they will collapse at their prey at great speed. They hunt from higher altitudes and in larger areas. Using thermals to stay in the air for a long time. Therefore, the eyes are more to the side and have a comb over the eye that (like a spoiler) conducts the wind along their head. You will see them hunt earlier during the day and over the fields where they can catch their prey more easily.
