I’ve always wondered whether eagles (and hawks, falcons, really any bird of prey that relies on their vision to hunt) can “zoom in” with their eyes just like it’s a camera lens. Because whenever I watch a nature documentary about eagles, the camera technique they show is that of a camera zoom, zooming in towards the prey hundreds of meters away.
I know that with human eyes, we can’t optically zoom in with our eyes. Sure, our eyes can focus on stuff really close to us, making the background blurry, but it’s not like we can “zoom in” to stuff far in the distance.
So to reiterate, can eagles zoom in to view objects in the distance like their eyes are a camera lens or binoculars with zoom?

Humans can “zoom in” too. Focus on a point within your field of vision. Now focus on a different point within your field of vision. You just “zoomed in” from one point of interest to another. Eagles just have a bigger and wider field of vision with higher resolution than we do.
