In the Kozagawa River, which flows through Kozagawa Town in the southern part of Wakayama Prefecture, during this season, ospreys, a type of hawk, can be seen jumping into the river and hunting for sweetfish that come down to spawn.
In the Kozagawa River in Kozagawa Town, so-called "falling sweetfish" can be seen heading downstream to spawn during this period.
In order to catch these fish, the osprey, a bird of prey called a "fish falcon", can be seen diving vigorously into the river with its wingspan of about 1.7 meters.
If you set your sights high on a tree, the osprey will dive at the right time.
Sometimes it fails, but it catches its prey with its sharp claws while splashing water.
The osprey is classified as "near-threatened" by the Ministry of the Environment and the prefecture, making it a valuable sight.
