Some older news, published by Olomouc zoo in July 2023. I post here direct translation of excerpts relevant to Cotia or Brazil. :
"On March 28, 2023, we reported on the trip of our wildebeest to the newly opened zoo in Cotia near Sao Paulo, Brazil, which resulted from a 4-year collaboration. It was the first ever white-tailed wildebeest traveling to South America. Other Brazilian zoos are also preparing to keep/breed this species, in order to create a separate/selfsustaining population."
"Researcher associate professor Jan Pluháček has been cooperating with Brazilian zoos for 4 years, especially the newly opened zoo in Cotia near Saõ Paulo. As part of this cooperation, the Olomouc Zoo delivered wildebeest there. The introduction of conservation programs for the Brazilian Zoo Association modeled after the EEP is currently under consultation."
