Forest Ranger Ganesha Lingam said a five member team of the wing, who were on patrol duty, on a tip off, rushed to the area and arrested J Bhavani (40) and M Gurusamy (52).
They also seized 200 gms of pellets and 100 gm of Sulphur and the vehicle used by them, besides the gun, he said.
Patrolling was stepped up in the area following reports about decline in the arrival of migratory birds due to incriminate hunting.
