At Priory we have been running a small project to see if there is a preference for the type of bat box used by bats. In 2009 we made and installed two types of bat box, carefully positioned them to see if the bats prefer one type over another and set up a monitoring regime to record what happened.
Currently (2011) we have five different designs of bat box installed in the park, making 41 boxes in total. The monitoring continues with the boxes being checked every month. The results so far have been very interesting, showing: • All the bats found in the boxes were Common Pipistrelles. • Slot type boxes have been used in preference to the wedge design. • The bats tend to use the boxes located in a limited area the park.
out of them as this means the box has to be taken down to fix. The reason we are using different designs of box in the hope we will encourage different species to use the boxes, such as the Noctule or Daubenton’s pictured below.
• Woodpeckers use them to make louder sounds for marking their territory, which damages the box. Bat boxes may take a longtime before use, however at Priory one CJM box was occupied within 18 days! Some of our boxes have now been ‘armour plated’ to try and keep the woodpeckers
