A French scientist was seriously researching this phenomenon can eat catfish pigeons living in the Tarn River, southwest of the country's windmills.

As reported by Plos One, European catfish originally lived on the river Rhine, but growing up the river Tarn, circa 1983.

Catfish in the river Tarn has a unique habit, which annexed the pigeons who stopped by the river, dragged him into the water and ate until sold out.

Through video circulating on YouTube, it seems a number of pigeons lined up on the banks of the river Tarn.

Seeing the many birds that come around, some catfish began to pull over to the edge of the river, it was almost up to the mainland. Within seconds, a catfish grabbed and dragged him dove deep into the water.

According to these researchers, the predatory nature of catfish is actually quite unusual, but these properties have been developed allegedly because it mimics the behavior of other fish that live in the river Tarn.
