Some two weeks ago Dalibor returned from his wintering grounds in Burkina Faso to the same area where he was nesting last year near Pilsen. During inspection of his nest it was clear on first sight that he has returned to the same one in which he spent time last year. New twigs have been added and faeces were clearly visible on the edge of the nest and on tree branches around.

Number of storks have reached the same nesting grounds on which they were marked and equipped with transmitters approximately a year ago. Unfortunately many of them did not return and died on their wintering grounds or during their return journey. In some cases we cannot exactly determine if they are alive or not, if they got delayed on the way or why we are unable to retrieve any signal about their location.

We did not have a record of a stork to taking a completely different route while flying to his nesting ground in comparison with the one he took while flying to his wintering ground. Only now in the case of Jaak who is flying around the Black Sea from the other side. Another thing worth mentioning is an extremely quick flight of Josephine - yesterday she covered 663 kilometres.

Spanish stork Esperanza is the first European stork that reached its nesting ground. Ten other storks are on their way. These include our two storks Tomáš and Dalibor. Six transmitters can still be found on the wintering grounds. Apart from Espartero it seems that Eliška died as well on her wintering ground... More about individual storks:
