The Zoological Society of Buffalo is the third oldest institution of its kind in the United States. The Zoo’s mission is to build community, create connections, and save wildlife. This is accomplished through the advancement of the science of zoology, the conservation of the world’s wildlife, and the innovative exhibition of diverse species of mammals, birds, reptiles, amphibians, and fish. 

Originally conceived as a deer park in the Frederick Law Olmsted’s Delaware Park, The Buffalo Zoo was established in 1875. Supported by local donations of animals, The Zoo grew and rapidly developed between 1875 and 1930, attracting great community interest and involvement. This growth led to the Zoological Society of Buffalo being founded in 1931. The Society worked with the City of Buffalo to effect many improvements to The Zoo over the next four decades. During this time there was a major renovation (1938-1942) by the Works Progress Administration (WPA), which featured buildings using classic, period architecture. 

Today, the philosophy of the Buffalo Zoo is to exhibit animals and plants in ecological habitats and geographic arrangements the represent the biomes of the world. Current programs focus on providing visitors with a better understanding of the natural world and how animals relate to each other, their environments, and humankind.
