The energetic demand of the Great White Pelican during migration in Israel and its implication to the conflict between fish industry and pelicans. Ostrich 71 (1 & 2): 1. The Great White Pelican Pelecanus onocrotalus is a migrating bird, which is an endangered species. The majority of the western Palaearctic populations stopover in Israel during their autumn migration (71 421 ± 127 individuals per year). Although most of these birds are transient over Israel, an increasing number of individuals (1 142 ± 882, between 1990–1994) stay and winter in the northern part of Israel. The natural feeding sites for pelicans diminished during recent decades due to human activities, and the aquaculture sites of intensive fishery became their favourite feeding places either during migration or during winter. The fish industry reports huge damages to fish yield. This study tried to assess ecophysiological needs of the White pelicans during migration and wintering in I... |
