International Bird Rescue is a nonprofit organization that rehabilitates injured aquatic birds, most notably seabirds affected by oil spills. Founded by Alice Berkner and members of the Ecology Action, including veterinarian James Michael Harris, D.V.M. in 1971 and based in Cordelia, California, the group has developed scientifically-based bird rehabilitation techniques and has led oiled wildlife rescue efforts in more than 200 oil spills worldwide, including the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska, and the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, where International Bird Rescue co-managed oiled bird rehabilitation efforts in four states with Tri-State Bird Rescue and Research.
