I just talked to John who will reply tomorrow from his office.
I suggest that you focus on estimating the numbers of oiled birds of each speciescoming ashore after the oil spill by gathering information on: a) beached bird deposition rates; b) carcass persistance rates; c) numbers of live oiled birds thatcome ashore and are taken to rehabilitation centers; and d) description of the extent of the oil spill at sea and when it affected coastal areas. It probably willbe too difficult to conduct aerial surveys of birds at sea or run models to estimate the numbers of birds lost at sea. So focus on trying to estimate how many birds of each species came ashore.
Three main data collection efforts are needed:
1) determine beached bird deposition rates and carcass persistance rates by conducting counts of dead and live oiled birds on a sample of beaches in different parts of the spill zone. This information is vital to estimating overall numbers of birds that wash ashore on all beaches. Every day lif possible) or every two days search for new oiled birds that have come ashore and look for old oiled birds on the sample beach. Make sure the beach or section of beach searched is well markedon a map. Don't dig up old dead oiled birds but let them stay on the beach as youfirst found them. Put a numbered tag on each dead oiled bird when first found andleave it on the beach. Don,t allow anyone to remove dead oiled birds from these sample beaches. If live oiled birds are removed, make sure that you document how many birds of what species were removed and when. These counts of oiled birds probably need to be conducted for a month at Least. Avoid getting oil on your hands or inhaling fumes if they are present!
2) conduct counts of beached birds on as many beaches as possible throughout the spill zone. After birds have come ashore for some days, conduct single counts of the numbers of dead and live oiled birds on beaches. These single counts permit surveys over wide areas in a few days with a small number of people. But make sureto continue the daily surveys (mentioned above) at the same time. Make sure that each bird is identified as best as possible to species. If people doing counts cannot identify all species, then get personnel to
