Hello. New info on Brazil's gibbons:
- 1958: Chiang Dai Sien, a Chinese teacher based in Mogi das Cruzes, donated a pair of lar gibbons to São Paulo.
- Between 1958 and 1970: São Paulo became the first Latin American zoo to breed gibbons.
- 1970: a lar gibbon was sent to Rio de Janeiro from São Paulo.
- Between 1968 and 1975: a lar gibbon was sent to Sorocaba, most likely from São Paulo.
- 1970s: A black lar gibbon was sent to Passeio Público, in Curitiba.
- 1980: the gibbon in Curitiba, named Negrão, escaped his enclosure, but he was soon returned.
- 1982: there was a male silvery gibbon somewhere in Brazil. There were four (1.3) lar gibbons in Brazil at the time, all in São Paulo.
- 1984: the silvery gibbon was apparently gone. The number of lar gibbons fell down by one (1.2), all still in São Paulo.
- Between 1984 and 1991: Another gibbon in São Paulo passed away.
- 1991: Two agile gibbons were imported to Brazil from the Netherlands.
- 1994: CITES lists a Dutch-originated gibbon being imported to Brazil from Germany. Weirdly enough, this gibbon was imported with commercial purposes.
- Around 1995: Another gibbon in São Paulo succumbed.
- 1995: An entry in CITES states two gibbons were imported to Brazil from Germany.
- 1996: Once again, there is a record in CITES of a gibbon imported to Brazil from Germany. I am quite sure this was the actual import instead of the 1995 entry.
- 1999: São Paulo had two gibbons.
- Mid-2000s: São Paulo lost another gibbon.
- 2008: There is a record in CITES which states São Paulo imported (or at least obtained the importing license) a lar gibbon from the Netherlands. There is also an entry from 2009, but I guess it was just a renewal of said license. This gibbon should be Julia, born in 2006.
- Late 2000s: São Paulo had two gibbons again.
- Around 2012: another gibbon (most likely the aging male seen by
@carlos55 ) died in São Paulo.
- 2017: Julia passed away
