An ecological characterization of Coastal An ecological characterization of Coastal Maine (north and east of Cape Elizabeth) ecologicalcharac02usfi Year: 1980 FEEDING HABITS FOOD RESOURCES PHYTOPLANKTON ZOOPLANKTON PLANKTONIC ^^^ >.

Feeding habits of estuarine fishes. invertebrates and vertebrates of the strand line (the supratidal zone where a community develops on the macroalgae that washes ashore). Shorebirds eat mostly intertidal mudflat invertebrates (, oligochaete and polychaete worms, amphipods, and the Baltic clam), squid, other invertebrates, finfish, zooplankton, and strand line invertebrates. Wading birds prey on reptiles, amphibians, finfish, insects, benthic invertebrates, birds, small mammals and some plant materials. Waterfowl feed mostly on benthic and other invertebrates, fish, and plant material. Brant are important herbivores, feeding on intertidal and subtidal algae (, Ulva), vascular plants (, eelgrass), and the invertebrate fauna associated with these communities. Ospreys are primarily fish eaters. Bald eagles in coastal Maine feed mostly on fish, waterfowl, and seabirds. Islands in estuaries are used for nesting (, bald eagles, ospreys, wading birds, gulls, eiders, and double-crested cormorants), rearing young (, bald eagles, ospreys, eiders, black duck, common and roseate terns, laughing gulls, and wading birds), moulting (, eiders and Bonapartes gulls), roosting (most groups), wintering (, bald eagles, black ducks, mallards, Canada geese, seaducks, purple sandpipers, gulls, loons, grebes, kittiwakes, and great cormorants), and as migratory stopover areas (, shorebirds, brant, geese, dabbling ducks, peregrine falcon, bald eagles, ospreys, diving ducks, Bonaparte's gulls, and ring-billed gulls). 5-45 10-80
