Competition in foraging flocks of migrating semipalmated sandpipers

  title={Competition in foraging flocks of migrating semipalmated sandpipers},
  author={Guy Beauchamp},
I examined the effect of competitor density on foraging success in staging semipalmated sandpipers (Calidris pusilla) foraging on a burrowing amphipod (Corophium volutator) in each of two study years. Little is known about the effect of competitor density when predation attempts disturb prey, causing a temporary decrease in food availability. Controlling for Corophium density and other potentially confounding factors such as temperature, pecking rate and capture rate increased linearly with… CONTINUE READING
