The Nest (Spanish: El Nido) is an aviary located in Ixtapaluca, state of Mexico. Founded by veterinarian Jesús López Estudillo in the 1960s, it is a civil association created to preserve over 300 different species of birds, both Mexican and the rest of South America, Africa and Asia, mostly endangered. The association—formerly known as Wildlife (Spanish: Vida Silvestre)—also has a space for breeding and conservation of the most endangered species.
