Sorensen (1981)

General information

This paper examined the feeding preferences of frugivorous birds in relation to the seasonality, abundance, growth forms, and nutritive/energetic value of fruit occuring in Wytham woods, near Oxford, South Britain.

Data type

The authors recorded their data by counting the number of visits of each bird species to each plant species. Data are presented as an interaction frequency matrix, in which cells with positive integers indicate the frequency of interaction between a pair of species, and cells with zeros indicate no interaction
