Surprisingly, mercury in seabirds is now actually slightly lower. This might appear to be good news, but unfortunately it is due to a decline in fish stocks near the surface which has forced seabirds to change their diet, and in the process to feed in areas low in bacteria (known as sulfate-reducing bacteria) which act to control the levels of mercury in their bodies.  McGill Newsroom.
