Bat researchers in Belgium report (translated):
Friday, November 21, 2014
The particoloured bat is a maverick amomg our native bat species. With barely forty sightings in Belgium it remains a very rare visitor. But there seems to be improvement coming: for 2014, the counter says eight observations. This autumn, the species was already observed seven times, and that’s a record. However, we should not just assume there is improvement because recently people have started to observe slightly more than previously.
