Abstract

Censuses of waterfowl at four fishponds and sandpits in the surroundings of Třeboň were carried out regularly during one season and theiroccurrence was compared with that recorded by other studies and information in the database of the Třeboňsko Protected Landscape Area.Some waterfowl show a marked preference for fishponds during the breeding season. This can be due to many factors, presence of morefood, extent of the littoral growth of vegetation, fish stock, depth of water etc. However, sandpits are attractive to waterbirds in winter, whenthey serve as over wintering sites, meeting places for migrating birds or refuges from hunters.
