Local Black Tern ( Chlidonias Niger ) population trends in relation to nest platform provisioning

The population of Black Terns in The Netherlands strongly declined in the period from 1950 to 1980. In recent years numbers have been more stable. The supply of artificial nest platforms has successfully attracted breeding Black Terns, and 80% now breed on platforms. In this paper we describe the development in numbers and breeding success of a Black Tern population in The Netherlands over the period 1982-2015, where ample nest platforms have been supplied over time. Using this database we question whether we can increase the breeding population by supplying platforms. We are uncertain whether... Mehr ...
