These Canadian geese never fly to Canada. They stay in Boston all year. Perhaps they still feel the inherited urge to follow someone to somewhere far away... - and satisfy that feeling by touring up and down our Muddy river instead of the blue Canadian skies... This photo was taken in 2003. Since then geese were recognized as a threat to the local ecosystem (they strip riverbanks of grass). Now their numbers are controlled by "egg oiling". As a result, you cannot see a gооse chain like this anymore. "Egg oiling" means literally rubbing eggs with oil. This prevents oxygen diffusion through the shell so embryo does not develop. They say this is better than removing the eggs because goose mother does not get upset (she keeps sitting on the oiled eggs) and because once eggs are removed she may lay more.
