How to Catch a Bird… If You’re a Fish

The video discusses how fish, particularly tigerfish, interact with birds. While most fish eat birds accidentally, tigerfish in South Africa actively hunt swallows using two tactics: lunging from deep water and surface pursuit. The success of these tactics is influenced by the refraction of light in water. Due to an artificial lake environment, tigerfish have adapted to include birds in their diet, which poses ecological risks. Researchers are concerned about the impact on both tigerfish and swallow populations and call for further study.
