Sažetak
Regular observations of birds in Osijek and surroundings areas have been made at the end of the last and the begining of this century. Similar observations in the same territory were carried out from 1982 till now to establish change in the ornithofauna of this area due to modified ecological conditions. Some less sensitive species are still found in this area, but more sensitive ones no longer exist. From 1896-1901 Rösler, 1898 noted 131 species of birds in Osijek and surrounding areas. From 1982-1987 92 species of birds were observed and noted. Seventy species are common in elaborated periods. Sixtyone species are not found in this district, and 22 species are new species. Species which are no longer present here are thowe living in the water habitat. This is in direct correlation with decrease of swampy soil near Osijek.
