From the Oiled Wildlife Care Network:
“We want to make it clear that the costs associated with this current response will be paid by the party responsible for spilling the oil.
If you would like to make a donation to the OWCN and its participating organizations for ongoing oiled wildlife care and rehabilitation activities, you can do so by sending a check to the Wildlife Health Center Foundation, P.O. Box 298, Davis, California, 95616. These donations will be used to prepare for oil spills in the western United States and internationally.”
