Data and code for "Low breeding propensity in a declining Arctic-breeding swan revealed by telemetry data"

This Zenodo entry contains data and code for "Low breeding propensity in a declining Arctic-breeding swan revealed by telemetry data". "comb_swans_clean_madebytheo.rds" contains the tracking data from MadebyTheo trackers (deployed 2016/17–2019/20)."comb_swans_clean_NiNa 1 contains" contains the tracking data from Ornitela trackers (deployed 2020/21–2022/23)."catch_data_2017" contains information on tagged birds, primarily their age, used to select adult birds (see Methods).All three can be opened directly into the R environment. "MasterCode_TT_11092025.R" provides the script which can be run, once the data is loaded, to reproduce the results. "breeding_results_all.xlsx" presents the outcome of our breeding assessment, which can be reproduced by following the scriptand our workflow for assessing breeding attempts and nesting success (as detailed in the manuscript).
