Bats! (Stuff I Compiled Teaching a Halloween Themed Science Camp)

  Bat Faces:
Bat Ears:
Bat Noses:

Bat Feeding Methods:

Some places they live:

Neat facts I learned (mostly from my science teacher mom, Lucy-Kate!):
  • Bats are closer related to humans than they are mice/rats.
  • 900 species worldwide
  • Mexican free-tailed bats can migrate up to 1,300 miles
  • Largest: flying fox--6 ft wing spam
  • Smallest: bumblebee bat from Thailand--2 oz weight
  • 70% of bat species are 'microbats'--typically insectovores
  • 30% are megabats--typically frugivores
  • Bat specialist Merlin "Batman" Tuttle has estimated that a single mouse-eared bat can catch up to 600 mosquitoes in just one hour
  • Frog-hunting bats, found in tropics, can tell if a frog is poisonous or too big to ear just by listening to the frog's call
  • Some bats echolocation is fine-tuned enough to "see" something the width of a human hair
  • Often bear one pup a year
  • Many fruit eating bats are -vital- for seed dispersal
  • Bat echolocation often uses multiple frequencies--high pitched that goes straight out and a lower pitched tone that is more diffuse.  Based on the percent reflection the bats can pin point where the reflection is coming from.  
  • Tree lures bats with specially shaped leaves that sound pretty.
