The dataset is from an observational study conducted along Skallelv, a sub-arctic river system on the east coast of the Varanger Peninsula in Norway.
Data on white-tailed eagle (Haliaeetus albicilla) abundances and pink salmon abundances and demographic stages were collected in two consecutive seasons using respectively, line transect counts and drift counts along Skallelv from July 1st to September 5th in 2021 and 2022. The associated R script has been used to analyse the data to evaluate whether there was an association between the pink salmon and white-tailed eagle abundances and produce figures that present the data with respect to such patterns as published in the article: Bonde, BM & Stien A. 2024.
