It is believed the father, 70, took aim at a quail and accidentally shot his son, 34.
The duo from Pascoe Vale, a western suburb in Melbourne, were quail shooting in marshland near Jarklin, about 60 km from Kerang, a rural town on the Loddon river in northern Victoria in Australia, when the accident occurred, the Herald Sun reported.
An air ambulance rushed to the scene where paramedics treated the man for wounds to his face and shoulder before taking him to Royal Melbourne Hospital.
The status of the seriousness of injuries could not be ascertained.
This was the second bird hunting accident this season. Earlier, a protester was shot in the face at Lake Buloke in the state's northwest on the opening day of the duck shooting season.
