Kokon are aquatic carnivorous birds of prey and live in aquatic ecosystems such as rice paddies, swamps, lakes, lagoons, waterholes, small canals and mangrove environments. Many non-native birds can be seen in our country and there are also some species that migrate to this country. They often roam the shallows of those aquatic environments looking for prey.
Dependent on fish and small aquatic animals, cuckoos have light bodies and long toed feet to avoid digging in muddy soil. It also has elongated legs and beaks suitable for catching prey in shallow water.
One of the most interesting features of cockroaches is the color changes that occur in the plumage, legs and beak during the breeding season
