  • hunt on/near ground, support all members of group; leap far distances accurately to catch flying prey

Critical Information

  • rainforests of Indonesia being destroyed like field of matches; global warming
  • habitat diminishing; increasing temperatures means less rainfall (rainforest needs rain); pet trade, also hurts humans (disease)
  • protected by international treaties, national law; need to improve public awareness (eat crop pests)

Vulnerable (could be Critically Endangered)
