SAviTraits 1.0: Seasonally varying dietary attributes for birds

Abstract Motivation Trait‐based studies remain limited by the quality and scope of underlying trait data available. Most existing databases treat species traits as fixed across time, with any potential temporal variation in measured being unavailable. This is despite fact that many are well known to show plasticity their characteristics over course year. paper describes a compilation species‐specific dietary preferences intra‐annual for 10,000 world's extant bird (SAviTraits 1.0). Information on was obtained from Cornell Lab Ornithology Birds World (BOW) online database. Textual descriptions species' were translated into semi‐quantitative information denoting proportion categories utilized each species. Temporal attributes captured at monthly resolution. We describe methods discovery translation present tools summarizing annual variability avian preferences. Altogether, we able document seasonal total 1031 (ca. 10%). For remaining species, either temporally stationary or diet not Main Types Variable Contained Temporally‐varying birds. Spatial Location Grain N/A.
