Utilization distributions (UD) of the annual cycle of migration in three species of wild migratory waterfowl wintering in the Republic of Korea from 2013 to 2016. Dark orange, light orange and yellow isopleths indicate 75%, 95%, and 99% cumulative UDs for each waterfowl species in one period, from 2013 to 2016. Common Teals UDs in: (a) The autumn migration from September to November (Period, n = 3 birds), (b) Wintering from December to January (Period 2, n = 8 birds), (c) The spring migration from February to March (Period 3, n = 8 birds), (d) Breeding from April to August (Period 4, n = 6 birds). Mallards UDs during: (e) Period 1 (n = 65 birds), (f) Period 2 (n = 147 birds), (g) Period 3 (n = 95 birds), (h) Period 4 (n = 41 birds). Spot-billed Ducks UDs during: (i) Period 1 (n = 20 bird), (j) Period 2 (n = 78 birds), (k) Period 3 (n = 44 birds) and (l) Period 4 (n = 26 birds). All UDs were estimated and plotted using R version 3.6.1 and ArcMap version 10.7.
