Abstract	Table S1. Sampled, estimated, and actual (censused) abundance of common terns Sterna hirundo and roseate terns S. dougallii in Massachusetts (MA), USA. Distance sampling abundance calculations of common, roseate, and/or mixed terns (‘CRMT’) across 2 or 3 surveys, are compared to 2010–2011 mean MA breeding population sizes (right column, calculated from Mostello 2011, 2012). For each cluster of tern observations (Obs.), the detection function (see Fig. S2) computes detection probabilities (p) over the distance range. These probabilities are used to calculate the estimated abundance (Estim. Abund.) of tern clusters and individuals (Ind.) over the entire study area (6750 km), based on the percentage of area covered by the sampled abundance of terns (N). The density-surface models (see Table 1 in the main text) fit N to the covariates, then predict abundance over the study area, based on the average of those covariates across surveys. Spr: spring
