Worth knowing

  • Their toes have special sticky pads that help them climb trees.
  • They are nocturnal, meaning they are most active at night.
  • They can survive freezing temperatures by producing a natural 'antifreeze' in their bodies.
  • Their call sounds like a musical trill or a bird singing.
  • They have bright yellow or orange under their thighs, which is a surprise flash of color.
  • Females are usually larger than males.

Why it matters

Gray Treefrogs help control insect populations in forests and wetlands. They are also a food source for many animals, showing how healthy an ecosystem is.
