Abstract
The recent status of Mute Swans in the Ukraine was surveyed by questionnaires, airplane counts, ground census and counts from boats, covering the area of inland water bodies. The data have been summarised and compared with information from other studies in various regions of the republic. Some preliminary results have been published elsewhere (Serebryakov 1984, Korzyukov 1987, Koshelev et al. 1987, Lisenko 1987).
