Brood data Nests were visited regularly to collect breeding ecology variables (i.e., brood size, fledge date, fledgling number, hatch date, lay date). Individual data The following individual-level data were collected: age, personality scores, plumage characteristics, size (weight, wing, tarsus, etc.). Genetic data The following samples were taken for genetic analysis: . Other genetic data collected/additional details supplied by the metadata provider: saliva. Environmental data The following biotic variables were collected: food availability. The following abiotic variables were collected: rainfall, snow, temperature. Other activities The following activities were undertaken: winter tagging. creator-1 dataCustodian Sebastian Dirren Schweizerische Vogelwarte Sempach sebastian.dirren@vogelwarte.ch 0000-0002-5638-5208 scientific collaborator Claire Pernollet Schweizerische Vogelwarte Sempach scientific assistant Christian Schano Schweizerische Vogelwarte Sempach 0000-0001-6365-8641 phd student and postdoc Irmi Zwahlen Schweizerische Vogelwarte Sempach scientific assistant Elisenda Peris Morente Schweizerische Vogelwarte Sempach fepmcorbera@gmail.com 0009-0003-1214-5151 scientific assistant Carole Niffenegger Schweizerische Vogelwarte Sempach 0000-0002-3851-7449 phd student Anne-Cathérine Gutzwiller Schweizerische Vogelwarte Sempach phd student Rolf Kessler Schweizerische Vogelwarte Sempach bachelor student Anja Lozza Schweizerische Vogelwarte Sempach master student Sidonie Nicole Schweizerische Vogelwarte Sempach scientific assistant The study was primarily financed by the Swiss Ornithological Institute and financially supported by Swiss National Science Foundation (project number 10.002.489), Swarovski, Yvonne Jacob foundation and an anonymous foundation Grasslands and lands dominated by forbs, mosses or lichens Alpine and subalpine grasslands Moss and lichen dominated mountain summits, ridges and exposed slopes 50000 ha The field study monitors artificial nest boxes, with a minimum of 60 and a maximum of 80 throughout the study period.
