This dataset includes mutualistic interactions between flowering and fruiting plants and all bird and (few) mammal species feeding on these resources. The data was collected on an area of 30 x 100 m on all study plots except for Hel and FEr, where mutualistic interactions could not be observed. All interactions were recorded using direct observations with binoculars following a standardized sampling procedure. Interactions were observed during 25 h distributed over 5 days on each plot.

This dataset was compiled by Maximilian Vollstädt. It includes all mutualistic interactions between birds and fruiting/flowering plants. All interactions were recorded using direct observations in the field following a standardized sampling procedure. Interactions were observed during 25 h distributed over 5 days on each plot. Each plot included all fruiting and flowering plants on an area of 30x100 m.
