Its brown feathers sticky with oil, the pelican tries to preen in the hot sun as men in white plastic suits lay absorbent pads on the rocky shore of Queen Bess Island off the coast of Louisiana.
Two wildlife rescue workers stand on a boat floating on the other side of a dirty yellow boom waiting for the signal to come start filling their cages. They'll have plenty of birds to choose from.
"There's one," says Dan Howells, deputy campaign director for Greenpeace USA, as he peers through his binoculars. "There's another one."
The oil is hard to see on the rocks. It just makes them look slick. But it clings in clumps to the grasses on the island's edge. And it clings to the feathers of the pelicans and terns that call this island home.
Queen Bess was the first place biologists brought fledgling brown pelicans when Louisiana worked to bring its state bird back from the brink of extinction in the 1970's.
Brown pelicans were nearly wiped out by the use of the pesticide DDT, which was washed off farm fields along the Mississippi River and poisoned the fish at the river's mouth.
Soon, pelicans started laying eggs with shells so fragile they would smash when the birds lay on them.
A ban on DDT and careful management of nature preserves like Queen Bess allowed the pelicans to thrive to the point where they were taken off the endangered species last November.
Now, they face the double threat of oil and chemical dispersants in the water and contamination from the fish that are swimming in it.
An estimated 40,000 barrels of oil a day has been gushing out of a ruptured well some 52 miles off the coast of Louisiana since the BP-leased Deepwater Horizon drilling rig sank spectacularly on April 22.
While BP has managed to siphon off part of the flow, it will likely not be fully contained until a relief well is completed sometime in August.
A further 1.2 million gallons of toxic chemical dispersants have been used to try to keep as much oil as possible out of the fragile coastal wetlands. Some 2.3 million feet of containment boom and three million feet of absorbent boom have been deployed to contain the spill. Berms are being built with rock and sand. Oil is being skimmed and burned off the surface of the sea.
Yet it keeps on coming.
Sullying shores and beaches as far away as Florida. Coating fragile grasses which are the only thing stopping the wetlands from being washed out to sea. And killing birds.
Some 530 oiled birds have been captured in time to be treated and hopefully released back into the wild. Another 712 bird carcasses have collected for evidence.
"A lot of the boom here is for show," Mr Howells says as he looks at the mud-streaked booms circling Queen Bess Island.
"When properly laid it can keep some of the oil out. But with any kind of waves it's either going to go over or it's going to go under."
Some of the boom has sunk under the water, leaving gaps for the oil to sneak past even on a calm day.
The Greenpeace boat heads further out to sea in search of thicker strands of oil on the surface. The water is relatively choppy as it steers past a boat skimming oil collected by booms being dragged across Barataria Bay.
