Seabirds eat plastic is well-known and nearly all the birds try this stuff and experience deadly consequences. The reason that the plastic bags or wrappers floating as trash appear so appetizing is that it smells like food and the birds eat it.
The debris, washed from streets to sea, sewers and landfills, gets collected into algae as it bobs up and down in the water. This algae emit a sulfur scent same as the algae produce odor that are the seabirds favorite meal. The plastic has krill and the scent is irresistible for the birds.
Savoca’s discovery informs that seabirds consumed plastic as it appears very much their food, or even ate by accident.
A study last year 90 percent seabirds, including petrels, gulls and auklets that actually live along the California coast are also found to have plastic in their guts. The percentage is drastically increasing from previous decades as more plastic is manufactured and dumped into the sea.
The stomachs of the birds contain waste as bags, clothing fibers, bottle caps and smaller plastic fragments from garbage that breaks down in water and sunlight. The birds become sick, and few die, as the plastic damages their innards or fill their bellies giving them a feel of being fully nourished.
After soaking the polyethylene high density beads, low-density polyethylene and poly-propylene for three weeks in the ocean, sewing the materials into mesh sacks is done so that they do not add to the pollution problem.
Savoca’s study observed that skillful sniffing seabirds track DMS such as shearwaters and petrels migrating through California, are more likely to eat plastic than other birds.
