I spent a couple of nights in Vienna in October 2016. I loved the city, which is now one of my favourites in Europe, but didn’t do much mammal watching.
I did spend a couple of hours in the late afternoon and evening at the Donaupark, near the International City. Brown Hares and Red Squirrels were common here but my main target were Parti-coloured Bats, that are reputedly common in the city in the autumn and possible to identify in flight from the audible calls the males give when they make display flights.
There were swarms of bats at dusk in the park near the lake, comprising at least two species. I am pretty sure I saw some Parti-coloureds, but did not hear any bats calling. I later learned that the males call in display flight near tall buildings rather than parkland.
