Same procedure in July 2001. Meanwhile more individuals are found repeatedly. Some N.n. marked in Plön have also been found in Kiel . There they have been seen in boxes in the Vieburger Gehölz and gaps between stones in the Levensauer Hochbrücke.
The Dieterich spouses have been regularly checking boxes and replacing them for at least 30 years and have been actively taking part in the development of modern bat boxes. This experiment on a tree offers different shapes - one more box at the back is not visible on the photo.
This Myotis daubentonii pretends to be dead, which is a great help because determining the species is much easier if the animal is not struggeling and it is therefore back in its box much more quickly.
These are not bat eggs but probably a Sitta europaea (Nuthatch) has left its clutch here.
The usual dual-use box: Probably Parus major (Great tit) has used the nest and already left again and above a group of N.n.
This N.n. is still a bit cold - in Summer many lower their body temperature during the day - and therefore it basks in the sun before taking off.
