Regarding Macaques, the two 'common' ones now are Lion-tailed and Sulawesi (and Barbary at the Trentham Forest place) I can't remember the last time I saw any Pig-tailed, Stump-tailed(Bear) Bonnet or Crab-eaters in a UK Zoo. Do any UK collections still have any of these?
Thought I would do a summary of all the remaining macaque species in Europe, being as I was rooting out the information for the ones you mentioned (which I will highlight in bold) anyhow
Assam macaque (
Macaca assamensis) is pretty much gone from Europe; there's one Russian collection on the border of Georgia but that's it.
Barbary macaque (
Macaca sylvanus) is held by 6 collections in the UK, at least two of which - Trentham and Edinburgh - breed regularly; this, plus the fact well over 100 collections in Europe hold the species, means it is secure overall.
Bonnet macaque (
Macaca radiata) is now absent from the UK, and only 8 collections hold the species in Europe as a whole. Think they are breeding relatively well though.
Crab-eating macaque (
Macaca fascicularis) is now only held by three collections in the UK - Shepreth, Curraghs and Wales Ape & Monkey - all elderly and non-breeding, so the species is doomed in the UK but with about 60 collections in Europe as a whole may hopefully hang on for a while yet overall.
Sulawesi black macaque (
Macaca nigra) is, as you noted, doing well in the UK with a total of 11 collections holding the species. It is actually not doing as well in Europe as a whole when compared to some of the species faring poorly here, with a total of only 29 collections holding the species, but as it breeds prodigiously this hopefully will not be an issue.
Heck's macaque (
Macaca hecki) is only found at Howletts in the entirety of Europe, and has been offshow for some time. This species likely will not last the decade in Europe.
Japanese macaque (
Macaca fuscata) are only held at two collections in the UK; Wales Ape & Monkey and Highland Wildlife Park. However, the success the latter collection has had in breeding the species, and the fact about 65 collections hold the species in Europe as a whole, means it is hopefully going to stick around.
Lion-tailed macaque (
Macaca silenus) is held by 5 collections in the UK, and 39 in Europe as a whole. As it breeds very well in the UK, this species is secure I think.
Moor macaque (
Macaca maura) is absent from the UK, and only found in 5 collections in Europe - the population is elderly and non-breeding.
Pig-tailed macaque (Macaca nemestrina) is now only held in the Uk at Drayton Manor; however there are a total of 40 collections holding the species overall in Europe so it hopefully might stick around there.
Rhesus macaque (
Macaca mulatta) is only held at 4 collections in the UK, although as I observed last week the population at Owl/Monkey Haven on the Isle of Wight is healthy and expanding. 65 European collections hold the species in total, so this species too may hopefully have a future.
Bear macaque (
Macaca arctoides) is held at 3 collections in the UK, all with elderly individuals, and a total of 22 collections in Europe - the majority in Russia. I think they are breeding okay in a few collections on the continent, so they might not be doomed.
Tonkean macaque (
Macaca tonkeana) is entirely absent from the UK, but breeds regularly in the 10 continental collections holding the species.
Toque macaque (
Macaca sinica) is only held by 3 collections in Europe, none in the UK - however the Berlin group regularly breeds and has done so since the 1980's so it might hang on in small numbers.
In summary, Bear Macaque, Pig-tailed Macaque, Crab-eating Macaque and Heck's Macaque are all likely to disappear from the UK, and in the case of the latter Europe too. Moreover, Assam and Moor Macaque are likely to disappear from Europe entirely.
