A challenger comes.
 
It takes over three years for a young male to grow the impressive adult horns which can spiral to 190 centimeters long and weigh up to 20 kilos.
 
The group of females attracts attention from would-be suitors. The alpha male is clearly unimpressed. The youngster will see what it means to be a top male.
