The following is a report by Steve Cardiff on a survey of shore and sea birds on Gulf islands. I am forwarding this with Steve's permission because authoritative information on the impact of the oil spill is almost impossible to get through the major media. Steve's report is just one of an increasing number that are beginning to come in through LSU and the Fish and Wildlife Service. I urge interested Ohio birders to subscribe to the LABIRD-L mailing list to stay informed. The time is coming when there will be a large scale rehabilitation effort with a similarly large scale need for volunteers. I am following this with another forward from Bob and Lucy Duncan, longtime regional editors for the Gulf coast for North American Birds. In it, the Duncans discuss BP's hold on public news releases and the appalling background on failure of the regulating agencies to carry out their duties, specifically with respect to endangered species, all referenced to reports in the public domain.

Blobs of BP Deepwater Horizon oil were conspicuously scattered along the length of the western 4-5 miles of the gulf beach of main Timbalier Island. Much of the oil was coating "trash" that had been washed ashore, human garbage as well as sargassum and other flotsam. But, there were also small to large blobs of the distinctive reddish oil on the sand itself. This stuff is commonly being referred to as "tar balls," but it's really has more of a peanut butter consistency. Along that stretch of Timbalier we had at least 22 out of 180 Sanderlings with varying amounts of oil on their plumage. Do the math and that's 12% of the Sanderlings that are oiled....... We saw one pair of American Oystercatchers, and both had oil stains on their belly plumage. Most of the oiled shorebirds were concentrated along the western 2 miles of the island where there was also more oil present, so the percentage of oiled Sanderlings along that stretch would be MUCH higher if I had kept a separate tally. Donna also had one dead Northern Gannet that had oil on it, but probably impossible to say whether it had succumbed to oil or had just become oiled as it floated in the gulf. Interestingly, a separate team working the eastern end of Timbalier Island did not report any oiled birds. None of the oiled shorebirds were moribund, but I would expect that all will eventually perish without a trace- these sorts of small birds with patchy oil contamination will likely just wander off and die horrible deaths in inconspicuous places. I guess the only good news is that shorebird migration will be gradually tapering off over the next few weeks, but anticipate heavy casualties among our later migrant shorebird species and summering populations of Red Knots and Short-billed Dowtichers. Anyway, if we are getting these levels of bird contamination with tiny amounts of oil hitting the islands, then....... Moving over to East Timbalier Island, there was a fair amount of oil along the gulf side and elsewhere on the island where there had been some recent overwash. But, the only oiled bird that we saw there was a Royal Tern with soiled back plumage. A few noteworthy birds that helped to slightly offset the gloom included an Osprey, a somewhat late Peregrine Falcon, two first-year Lesser Black-backed Gulls (plus a 2-3 year bird at Grand Isle today), a couple of Mourning Doves (migrants?), a couple of Belted Kingfishers, small numbers of migrant swallows moving east into the wind (15-20 Banks, a Cliff, and about 60 Barns), lots of territorial Marsh Wrens, a female Blackpoll Warbler, a Northern Waterthrush, and 10 Bobolinks (in ones and twos, only 2 males). Additional surveys planned for today (Sat. 5/15) were cancelled due to rain and high winds. Both Thursday night and Friday night at Grand Isle we were treated to the stench of oil brought in by the strong SE winds. Elmer's Island was open but there was constant truck traffic that made it less than enjoyable. Some other LSU bird personnel were out there on separate projects and may have more details on impacts associated with filling in shoreline breaches near Caminada Pass and at the mouth of Bayou Von Thunder Considerable fill material is being brought in, but I shudder to think of the disturbance to nesting plovers and Least Terns. We had 26 pairs of Wilson's Plovers there last Friday, some of our highest densities anywhere so far. Fourchon Beach was closed, with a road block before the bridge and National Guard bulldozers and other heavy equipment everywhere. Presumably, they are filling other breaches in the shoreline east of the beachhead to protect the marshes.
