Preliminary results indicate that, deer were the most commonly preyed upon item (66% of kills) followed by elk (29%) and non-ungulate (i.e., coyotes, raccoons, etc...) prey (5% of kills).

However, there are differences between male and female cougars. Male cougars tend to prey on elk more frequently than female cougars.

Female Cougars:

• Elk make up 25% of kills
  
• Deer make up 72% of kills
  
• Non-ungulate prey make up 3% of kills
  

Male Cougars:

• Elk make up 45% of kills
  
• Deer make up 44% of kills
  
• Non-ungulate prey make up 11% of kills
