Data for paper "Wing morphology changes with habitat availability and elevation in an alpine-specialist bird", Global Ecology and Conservation

This database includes the data used in paper “Wing morphology changes with habitat availability and elevation in an alpine -specialist bird”, Global Ecology and Conservation (https://doi.org/10.1016/j.gecco.2024.e03276). Measured birds were captured during the breeding period with mist-nets and spring traps at seven study areas in the central-eastern Italian Alps during spring/summer 2021 and 2022. Primary feathers lengths (P9-P1) were measured by a metal ruler (± 0.5 mm). Age and sex were determined according to Demongin (2016) and Strinella et al. (2013). The extension of suitable habitat within a 10-km radius around each sampling area was derived from Ceresa et al. (2024). Within the same radius, winter mean temperature and precipitation were calculated using data from the CHELSA database (BIO11 and BIO19, Karger et al. 2017).
