Twenty-nine species of ducks, grebes, loons, cormorants, and gallinules have been observed in the mangrove habitats of south Florida. These floating/diving birds feed on fishes, plant materials, and invertebrates. Many species regularly visit or live in these areas, taking advantage of the abundant food the estuaries provide. The dead birds I find washed up are, nine times out of ten, gannets. Add in items like Deltaport’s proposed Terminal Two expansion which would take out the biofilm required for migratory birds at Roberts Bank, and you can see the pressures on this ecologically unique area. Find the perfect estuary birds stock photo. Of the more than 600 species that live in the estuary, the study found 102 are at serious risk, including Southern Resident killer whales, five species of salmon, green and white sturgeon and migratory birds such as the western sandpiper.
