The cold and windy wheather in June was also bad for the colonial breeding Herring Gull and Lesser Black-backed Gull which had their chicks hatching just then. According to preliminary results, only 0.2 chicks / pair fledged.

On the other hand, three species that colonized the island only in recent years were quite successful. The number of the breeding pairs of Spoonbill increased from 19 (2008) to 25 (2009), and their breeding success was high. 19 chicks of Barnacle Goose (5 breeding pairs) could be observed in the end of May already, and 4 Peregrine Falcon chicks fledged. Finally, 93 chicks of Shelduck could be observed feeding on the mudflats, whilst only 15 were observed in 2008.

The following table gives the breeding pair numbers of all breeding bird species in 2009. In addition, the year is given, when the respective species was first recorded as a breeding bird on the island. However, not all species were breeding regularly. E. g., in the last years Sandwich Tern breeds only sporadically in very low numbers.
