In 2008 the zoo refurbished the information area of the exhibit and included a nice display on Light Pollution. On a typical day, several hundred people passed by the display. Special thanks to Mette Hanson for doing the artwork on the display.
The main reason the zoo is closing the nocturnal house is that it requires too much energy to keep its main large displays heated. It is possible that the display will be reopened in the future after being rebuilt with a more efficient heating system. It is not being closed due to lack of popularity.
