cleaning-oil-from-brown-pelican-during-Gulf-oil-spill
Brown pelican during the rinse phase of the wash. Each bird (with a rare exception) was washed only once but in 2 or 3 successive tubs, depending on how much oil was on them. Once a tub was saturated with oil, the bird was placed into the next “layer,” or tub, as the water could no longer effectively remove oil. Once the water no longer became discolored from the oil, the bird could then be rinsed.
