Bat spotting in Amsterdam


Bats can go relatively invisibly throughout the city unless you know that they are there. The bats in Amsterdam are very small and can easily be mistaken for birds by the untrained eye.


The province of North Holland has some of the best resourced bat experts in the world. I was lucky enough to meet one of them with Natuur je Beste Buur, the environmental group I volunteer for. It was incredibly fun and educational. We went for a walk around the sports parks and spotted several bats flying around.


We learned a lot in one evening, too much to share everything, but I will share as much as I can.


Here are 10 amazing facts about bats:


  • Bats begin their day at twilight, this is the most likely time that you will see them
  • They do not like wet or windy conditions
  • Bats can eat up to 3000 bugs in one night; this is brilliant if you have a mosquito problem.
  • They use echo location to detect the bugs.
  • With a bat detector you can hear the echo location and therefore locate the bats and identify them.
  • You can attract bats to your garden by providing them with a bat house
  • Bats make up ΒΌ of all the mammals on the planet
  • Bats are not a danger to people if they are left undisturbed
  • There are 1,300 kinds of bats in the world, but just 4 in North Holland
  • Most Bats around the world are endangered due to habitat destruction and prejudice


Once we knew what to look for, we spotted 3 bats flying around our tiny little garden just a few nights later
