I've been working alongside International Bird Rescue's Oil Spill Response Team for many years. They are super dedicated group of folks that have worked on spills all over the world – including many where there was no reporting party and no funds were promised. When their team's are mobilized, they hit the ground running with the primary object of helping wildlife in distress.
The South Africa spill is a good testament of their passion and teamwork: http://bird-rescue.org/success-stories/saving-20,000-penguins.aspx
Review from Guidestar
I have been working with International Bird Rescue for 13 years. They have always been an incredibly valuable resource to other Wildife Rehabilition centers and individuals throughout the state and country, in fact, internationally. My experience has been that they have always been kind, caring, incredibly hard working and worthy of great honor and respect. I love them as individuals and colleagues and feel because of them, thousands of waterbirds have been saved. They deserve the highest commendation.
