Common kingfishers hunt for prey from a perch above the water. Perches may be several centimeters to several meters above the water. When they see potential prey, they dive into the water, grab the prey, and fly back out. Sometimes when a perch is unavailable they will hover above the water to search for prey. After catching a fish, common kingfishers will hold the prey by its tail, and whack it against the perch. This stuns or kills the prey, which is particularly important when eating fish with spines. After consuming a fish it will regurgitate a pellet of indigestible bone.
Common kingfishers eat mostly small fish, making up 60-67% of their diet. They may also eat small arthropods, such as Gammarus fasciatus. Crustacea consist of 5-33% of their diet. Common kingfishers have also been known to eat crabs and other small marine animals during the winter.
