The kingfisher solves this problem with a second fovea in each eye. Once the eyes are immersed in water, the image of the fish is focused on the second fovea in each eye. That means that there is stereoscopic visualization of the prey as it tries to dart away, an action that is usually not successful.
But, in order to keep the image focused on both foveae, the lens has to be oval and the second fovea has to be in the periphery of the eye at the edge of the retina.
No, when hunting for fish, they hover above the pond, then swoop in to pick them up out of the water
i think it is important, so that it can see its prey from anywhere
fish
Kingfishers are carnivorous. They get their necessary nutrients from fish, which they devour whole.
To survive, Kingfishers hunt Fish and other river animals like Nymphs.
to catch fish
Birds like kingfishers hover high above the water before diving in to catch the fish because they are getting ready to dive. They are watching the fish and making sure it knows where it is in the river.
Mainly minnows and sticklebacks (all small fish's)
basically it depends on what kind of fish for example kingfisher. Kingfishers have a big capacity for food-basically kingfishers eat fish.
They feed almost entirely on small fish.
Some kingfishers eat fishes, amphibians, crustaceans and water insects, which they catch by diving into the water head-first. Most eastern hemisphere kingfishers don't fish, and the forest or wood kingfishers may live far from water.
All kingfishers eat fish, hence the name.
