The pelagic ecology of the Grey and Red‐necked Phalaropes Phalaropus fulicarius and P. lobatus in the Bay of Fundy, eastern Canada

摘要: The outer Bay of Fundy, eastern Canada, is an important feeding area for migrant Grey and Red-necked Phalaropes Phalaropus fulicarius P. lobatus in late summer. birds feed on copepod-sized zooplankton, brought to the surface by passage strong tidal streams over shallow, rocky ‘ledges’, concentrated there upwelling convergence ‘streaks’. Feeding phalaropes are significantly more abundant ‘streaks‘ than adjacent ‘contro’ areas. common species; they prefer New Brunswick shore, where copepod biomass high species-community dominated large, Stage VI-V Calanus finmarchicus. occur mainly Nova Scotian side biomass, dominant species, smaller. habits both their non-breeding distributions, reviewed. It concluded that upwellings, convergences, other oceanographic phenomena concentrate zooplankton at principal factors influencing pelagic ecology phalaropes.
