This is a thread following on from a discussion me and @David Matos Mendes had about creating a post regarding the specialities / expertise that zoos within Brazil have with different species. I hope that it is informative for the zoochatters who are curious about zoos here and gives a decent picture of these institutions and their contributions to ex-situ conservation etc. So I'll begin with two of the smaller zoos here in the State of Sao Paulo that are often overshadowed by the larger and better funded Sao Paulo zoo but that nonetheless perform a very valuable role in ex-situ conservation management of endangered native species. Guarulhos zoo : The speciality of this small but decent zoo is unquestionably the endangered Buffy tufted marmoset (Callithrix aurita) known in Brazil as Sagui-da-serra escuro and also the "Sagui-caveirinha" ("The little skull marmoset" due to its facial markings which people believe to resemble a skull). This marmoset is currently only kept in a handful of Brazilian institutions and has historically proved to be a very challenging species to keep (attempts to keep colonies alive in the Rio Primate Centre consistently failed). The studbook keeper for this species is Dr Claudia Igayara who is also the manager of the zoo, chief vet and the president of AZAB (the association of Brazilian zoos and aquariums). Claudia has achieved a lot of success in terms of both breeding the species and determining its dietary / nutritional needs in captivity. The zoo works closely with the NGO responsible for the conservation of this species " The Mountain Marmoset Conservation Programe" (or MMCP) and has also been heavily involved in genetic studies and field studies of hybridization (one of the principal threats posed to this species in the wild). Worth mentioning that the focus of Guarulhos zoo is mainly geared towards native species and only a couple of species here are not native to Brazil (African lions, common snapping turtle and turacos). Sorocaba Zoo: The speciality of this zoo (and it's logo) is also unquestionably a primate species but this time it is the largest monkey of the Americas: the Southern muriqui (Brachyteles arachnoides) also known as the "mono carvoeiro" in Brazil (the "charcoal monkey" because its facial pigmentation was said to resemble the face of a charcoal burner covered in soot). Beginning in the early 2000's with a single founder individual (a female which was found as an orphan in the wild) the muriqui colony has grown significantly over the years (composed of individuals rescued from captivity or orphaned in the wild) and has bred several times. The zoo also has a very impressive breeding record for the maned wolf ( as a zoo it is among the most successful breeders of this species in the word) and litters are born here pretty much every other year. In addition to this there are breeding programes for a number of other endangered native animals such as jaguars, the giant anteater, several cracid species, a number of tamarin species and the pampas deer. The focus of Sorocaba Zoo is mainly on native species which form the majority of the collection but there are some exotics here too (African lion, Bengal tiger, spectacled bear, sacred baboons, meerkats, ringtailed lemur, mandrill, Asiatic elephants, hippos, Burmese python, red deer, llamas, grey cheeked hornbill, pheasants etc). I'll let @David Matos Mendes take it from here and continue to give the overview of some of Brazil's other zoos and their expertise in species conservation.
