Data from: probing variation in reaction norms in wild populations: the importance of reliable environmental proxies

Data contain phenotypic breeding data and NAO data for the Common guillemot as described in Reed et al. (2006). These data were used as one of the two practical examples in the paper. See the readme file for details. For questions regarding these data, please contact Michael P. Harris ([e-mail]). For R scripts used to analyze the data, please see the supporting information to the main article associated with this dataset (Ramakers et al. 2023).
