Area bird counts are conducted every month at the site during high tide using binoculars and spotting scopes. The site is partitioned into 250 m UTM grids so that observers can reference the location in which birds are detected. Observers record grid #, bird species, number, behavior (i.e., foraging, roosting, calling, flyover, swimming) and habitat (i.e., mud flat, marsh plain, open water, aerial, upland or levee). Birds are grouped into foraging guilds for analyses and trends. Breeding birds or nests will be recorded if encountered. Bird species richness, density will be tracked over time and related to changes in sediment levels. The enhanced freshwater wetlands area are also included in these surveys.
