The Utrecht canals are an important habitat for bats. In recent years, these valuable animals have increasingly been given the attention and protection they deserve. Bats still too often lose their winter habitats during restorations because cellars are heated. On the other side, in the quay wall, pits and other hollow structures have been made where bats thrive. On summer evenings you can see the bats actively flying in and out. Bats emit sound waves whose reflection is observed subsequently. In this way they can determine exactly where their prey, an insect, is flying.
