• Some gulls, such as this Mew Gull, move their feet rapidly up and down.
  • This creates an upwelling which helps bring food from the bottom to the surface where the bird can get it.
  • This type of activity is very common in streams where salmon are spawning.
  • By doing this the gulls bring salmon eggs laying on the substrate to the surface.
  • In this case, however, this gull is standing in an intertidal area.
  • This activity brings tiny Macoma clams from the bottom to the water surface where the gull can grab them.
