The use of artificial floating nest platforms as conservation measure for the common tern Sterna hirundo: a case study in the RAMSAR site Druzno Lake in Northern Poland
Artificial nesting sites with floating platforms may effectively support local breeding populations of waterbirds (enhancing productivity and survival) when natural sites are unavailable. In this study, we installed three artificial floating nest platforms (one in 2017, two in 2020) and we evaluated...

We conclude that artificial breeding platforms may be a good conservation measure for common terns in natural areas with limited access to breeding habitat (but with optimal foraging areas). Based on our experiences from the present case study and on experience of other authors we propose recommendations for constructing, placing, and maintenance of nest platforms for common terns.

Artificial nesting sites with floating platforms may effectively support local breeding populations of waterbirds (enhancing productivity and survival) when natural sites are unavailable.
