Abstract

Knowledge about breeding success is relevant for understanding the trends observed in local and regional breeding populations of waders, terns and gulls. This report compiles results from surveys of breeding success of Oystercatchers and terns breeding on the island of Mandø, and of terns and gulls breeding on the island of Langli. Both islands are located in the Danish Wadden Sea. Oystercatchers were monitored in 2010 and 2011 and bred successfully in one of these. Common Terns and Artic Terns were studied on Mandø mainly in 2009-2011 and they bred with very poor success in all years. Successful breeding of Sandwich Terns was recorded on
Langli in most of the years during 2006-2010. The Lesser Black-backed Gulls and
Herring Gulls that nested on Langli were fairly successful in raising young to fledging
during 2009-2013, whereas Common Gulls suffered from predation by Herring Gulls
and they hardly raised any young. It is concluded that a future low cost monitoring
programme of breeding success could focus on Oystercatchers on Mandø and
Herring Gulls on Langli.
