Abstrakt		From the mid-eighties onwards, an increase in the population of the Black Stork and its range have been noted in Slovenia, just like in some other Central European countries. The bird's new natural surroundings do not differ from the already described ones in the neighbouring countries; they are predominantly woody and somewhat distant from man. From June to August 1994, a pair of adult Black Storks frequented the NW part of Ljubljana. While circling in the air, the birds occasionally showed the elements of teritorial flight and courtship. There was no other evidence, however, about a potential attempt to breed there. The observations were made from up to a kilometre wide open area between a densely populated residential area and the motorway. As than 50 m from the edge of the residential neighbourhood and circled a number of times above this area. The estape distance of the bird standing in the pole was about 10 m. This open area is a highly frequented promenade and consists of approximately equally large fields, meadows and a mixed forest. The only waters suitable for this bird are the two regulated and deepened streams which are due to their eutrophication known for lush vegetation and fauna. The two stroks presumably fed there.
