Roof-breeding Oystercatchers

The Eurasian Oystercatchers Haematopus ostralegus are nesting again on the Realfagbygget roof.

Arild Breistøl


The Eurasian Oystercatchers Haematopus ostralegus usually breed on the ground in open areas. The concept of roof-breeding is known from different sites. Aberdeen in Scotland is known for its population of roof-breeding Oystercatchers, counting about 230 pairs in 2004. In other countries the phenomenon is more uncommon, but is recorded (at least) in the Netherlands, Belgium, Finland, Latvia, Germany and Norway.
