Albatrosses belong to the order  Procellariiformes, with a tubular nose and a keen sense of smell, and often fly long distances at sea in order to find food. The plastic trash floating on the sea doesn't look delicious, but why did the albatross eat it and pay a heavy price for it? The researchers believe the reason: for albatrosses, the plastic garbage smells delicious. Food signal is a chemical called dimethyl sulfide (D.MS), which is produced by marine phytoplankton.
 Birds of the order Gebliformes that are sensitive to the odor of D.MS can detect very low concentrations of odor molecules does not support the researcher's point of view.
