We compiled data from 11 studies that used mist-nets to sample birds within different areas of endemism across Amazonian terra firme forests. Mist-net studies used here were implemented with distinct designs, goals and contexts (see Appendix S1 in Supporting Information), resulting in large variation in the number of captured individuals per landscape (between 389 and 3,582 captures for long temporal sampling).
We focused on understorey terra firme species and removed species that fit at least one of the following three criteria: i) species that are not typically found in the understorey (i.e. species that preferably inhabit the midstorey and canopy); ii) species that inhabit mainly open-habitat areas (e.g. campinas); and iii) species that inhabit flooded areas but that may occasionally also occur in the understorey of terra firme forest (see Appendix S2 in Supporting Information). Species selection was based on two databases (Stotz et al., 1997; Wilman et al., 2014) that contain information on habitat use and foraging stratum (understorey, midstorey and canopy). The list was subsequently revised by two ornithologists with extensive field experience in Amazonia. We also excluded recaptures from all analyses as we were interested in the number of individuals per species.
There are 2 different datasets:
1. "Capture data.csv": Capture data of understorey birds, sampled in seven Amazonian areas of endemism. Each line corresponds to a species and the number of individuals captured in each sampling area, with the respective information on food guild and body size, sociability and foraging substratum.
2. "Metadata.csv": Metadata of the items 'sociability' and 'foraging substratum'.
