Article body
Mission Bay was a lagoon nestled inside of a +500 acre salt marsh and was occupied by year-round tidal waters. This area was a natural habitat and refuge for large waterfowl populations that included ducks, geese, herons, egrets, ospreys, and gulls. The Native American tribes who lived in this area were the Costanoan people who spoke eight different languages which delineated between the various tribelets. The tribe most prevalent in the Bay area was the Patwin people who lived in the area for over 5,000 years.[citation needed] By the early 19th century, European immigrants exposed the population to various deadly diseases that reduced the Patwin population dramatically.
