The Allegheny Bird Conservation Alliance (ABCA) is a strategic partnership between local and national conservation organizations who have a strong focus on the conservation of birds.  Partner organizations include Carnegie Museum of Natural History, National Aviary, Western Pennsylvania Conservancy, Audubon Society of Western Pennsylvania, Humane Animal Rescue, Allegheny Land Trust, Pittsburgh Parks Conservancy, and the American Bird Conservancy.  ABCA exists in order to help focus each partner organization's individual conservation efforts, and to create and identify collaboration opportunities.
