Trends in breeding phenology across ten decades show varying adjustments to environmental changes in four wader species
Capsule: During 1928–2016, initiation of egg-laying advanced in two wader species, remained unchanged in one, and was delayed in one species. The changes across years and variation among species can be explained by climatic variables and differences in migratory strategies. Aims: To document possibl...
