Students from the Mundaring Christian College recently completed a workshop building micro bat boxes.
They had to research the requirements that the bats need to live and breed in a successful artificial habitat.
Based on these findings five trees were selected as potential installation sites. The boxes were installed and a GPS was used to record locations for further studies.
The area chosen is called Black Cockatoo Reserve situated at the rear of the school. A representative from the Friends group was on site to view the installation of the boxes.

Found a little bat in my shed – he was ‘roosting” inside a curled up sheet of sand paper! Scared the heck out of me when I unrolled the sheet – I had no idea what it was at first…..Light chocolate colour small ears – googled images and closest I could get was the Chocolate Wattled Bat – but not sure if they are here in Perth (I am in Helena Valley bushland & have always seen bats flying at night here). Anyway I showed my girls who at first were terrified (4 & 7 yo) but after I pointed out how beautiful he/she was they became fascinated and wanted to learn all about them. Anyway I returned it to the roll of sandpaper and a few minutes later off it flew. (It was just turned night). I will keep an eye out for it in the future. I have a picture if you would like to have a look let me know.
