Natterjack in concert

New rock band? No, ... just a couple of toads. When dusk sets in the Natterjack's (Epidalea calamita, formerly Bufo calamita / Rugstreeppad) concert starts. It is deafening; look at the large vocal sac (kwaakblaas). Great to be one of the spectators. Night photography is fun!
