Rasmus Sandsten, spokesman for underground operator MTR, said the pigeons have been catching the train from Farsta Strand to the Farsta Centrum shopping center, only one stop away, where they regularly forage for food, The Local reported Thursday.
"They stand calmly at the platform and wait for the subway train to arrive. When it does they get on, travel one stop, jump off and then head for their favorite haunts," Sandsten said.
Sandsten said the food they find at the shopping center apparently gives the pigeons the energy they need to fly home.
"We haven't been told of as many incidents of pigeons on the tube on the way back, so we think they fly on their way back," Sandsten said.
