From the Ground: BP Censoring Media, Destroying Evidence, Riki Ott, June 11, 2010:
BP is... raking up carcasses of oiled seabirds. "The heads separate from the bodies," one upset resident told me. "There's no way those birds are going to be autopsied."...
NOAA should also be conducting carcass drift studies. Only one percent of the dead sea birds made landfall in the Gulf of Alaska, for example.
That means for every one bird that was found, another 99 were carried out to sea by currents.
Further, NOAA should be conducting aerial surveys to look for carcasses in the offshore rips where the currents converge. That's where the carcasses will pile up--a fact we learned during the Exxon Valdez spill.
