Parental care varies across animal taxa, from uniparental to biparental care, driven by ecological and social factors such as weather, food availability, predation, and partner availability. Understanding this diversity within species can reveal biotic and abiotic conditions allowing uniparental versus biparental strategies. This study examines the impact of biotic and abiotic factors on parental care strategies in Sanderlings (Calidris alba), one of the few species that uses both types of care. Using long-term data from Greenland (2011-2023), path analyses revealed that laying date and snowmelt influence parental care strategies, with indirect climatic effects during migration and on breeding grounds. We observed a greater proportion of uniparental nests in years with delayed laying dates, and a greater proportion of biparental nests in years with delayed snowmelt. These findings underscore the complex interplay between environmental factors and parental care strategies, offering insights into how these ... : Funding provided by: Agence Nationale de la RechercheCrossref Funder Registry ID: https://ror.org/00rbzpz17Award Number: ANR-21-CE02-0024 Funding provided by: Institut Polaire Français Paul Émile VictorCrossref Funder Registry ID: https://ror.org/011ed2d57Award Number: Interactions 1036 ...
