nest site selection in swans
The warning climate is giving migratory birds new opportunities to extend their breeding ranges. These expansions may have a significant impact on other local bird communities. Here, we investigate the nest site selections of Mute Swan Cygnus olor and the expanding Whooper Swan Cygnus cygnus. The st...

The warning climate is giving migratory birds new opportunities to extend their breeding ranges. These expansions may have a significant impact on other local bird communities.

It examines the number of breeding pairs and the surface areas of nesting zones in different habitat types.
