As anyone who has bird watched around these parts in the last 20 years can tell, it’s pretty clear we have lost seabird populations. Now some new scientific data has come out on the problem.
Seabird populations in Puget Sound have declined since the 1970s and scientists believe pollution is partially to blame. But how do you prove that? Study what the seabirds are eating. A new paper [http://www.sciencedirect.com/science/article/pii/S0025326X14004226] published in the journal Marine Pollution Bulletin found that seabirds in Puget Sound are eating fish that are two to four times more contaminated than fish on Washington’s outer coast.
