Species overreporting indexes. (A) Counts of bird overreporting indexes by significance level, controlling the false discovery rate (FDR) to account for multiple comparisons. The odds of appearing in iNaturalist for the most underreported species (B) were between 0.002 and 0.13 as small as in eBird, while the odds for the most overreported species (C) were roughly 1.6 to 45 as large as in eBird. The bottom axis shows the overreporting index on the log scale as used elsewhere in this paper. The top axis shows the index on the real scale. For each species, the index is plotted with its 95% CI.
