there are all kinds of birds dying, along with fish and crabs. judging by the areas where the fish and crabs are showing up, it looks like its probably aftermath of BP's oil spill. no clue about the birds though...possibly natural gas or methane??
i wouldnt be too worried about it though, on average, 143 reports of mass die offs like this are reported every year. its just getting so much buzz now because we are so close to 2012.
