Have you ever been stared at by a #BlackSwan (Cygnus atratus)? Just happened to me while visiting the grounds of #Rurich Castle - https://de.wikipedia.org/wiki/Schloss_Rurich - not for from the bluebells zone https://scicomm.xyz/@cosmos4u/110295961028912032 in #Hückelhoven (see https://share-your-photo.com/05e1565ba7/album for more pictures).
