Percentages of utilization of various habitats by waterbird species. Habitat use codes are (DW) deep waters of >30 cm deep without emerging vegetation, (DWV) deep waters of >30 cm deep with emerging vegetation, (MW) medium waters of >10 cm and <30 cm deep without emerging vegetation, (MWV) medium waters of >10 cm and <30 cm deep with emerging vegetation, (SW) waters of <10 cm deep without emerging vegetation, (SWV) waters of <10 cm deep with emerging vegetation, (MU) mud without emerging vegetation, (MUV) mud with emerging vegetation, (DR) dry areas without vegetation, (DRVA) dry areas with vegetation away from the periphery of the lake, and (DRVN) dry areas with vegetation near the periphery of the lake. Guild codes are (H1) deep-water birds, (H2) medium-water birds, (H3) shallow-water birds, and (H4) generalist birds in waters with vegetation in both peripheral and interior zones.
