What Extinct in the Wild Species Have You Seen?

So far I've seen...

Greater Vancouver Zoo
  • Père David's deer (Elaphurus davidianus)
  • Scimitar oryx (Oryx dammah)
Smithsonian's National Zoo
  • Guam kingfisher (Todiramphus cinnamominus)
  • Socorro dove (Zenaida graysoni)
And while this is not a list I'm hoping to expand, I do wonder if any endangered species I've seen will count for it someday :(
 
With this latest IUCN red list update, the number of species assessed as EW has actually remained unchanged, with uplistings counterbalancing downlistings.

The real headline news is of course the downlisting of Scimitar-horned oryx from EW to Endangered.

Another species was also reassessed as no longer EW: the wild mango species Mangifera rubropetala, as some populations in Malaysia and Sumatra, previously thought to be cultivated, apparently may be wild.

This is balanced out by two other plant species being added to the EW list: the Hawaiian lobelioid Brighamia insignis, previously listed as Critically Endangered (possibly Extinct in the Wild), and the Colecillo (Dendroseris gigantea), a shrub endemic to Alejandro Selkirk Island off the coast of Chile, also previously assessed as Critically Endangered.

There's a few species around in zoos that may already be Extinct in the Wild, or very nearly are. One that's probably been seen by many zoochatters is Edwards'/Vietnam pheasant (Lophura edwardsi), which has possibly been unrecorded in the wild since 2000. Javan pied starling (Gracupica jalla) has seemingly been lost too.

Various Asian freshwater turtles have also gone a concerning number of years without wild records; McCord's box turtle, Roti Island snake-necked turtle and red-necked pond turtle have all possibly disappeared, as has Zhou's box turtle, whose wild range was never identified in the first place.

Currently Critically Endangered species present in zoos that are really on a knife's-edge in the wild include Javan green magpie, ploughshare tortoise, addax, and many amphibians and freshwater fish.

Wasn't the Pere David's deer reintroduced a long time ago? What are the criteria to "upgrade?"

Main criterion for downgrading from EXW: "The IUCN Red List Guidelines state that movement out of the Extinct in the Wild (EW) category can be done after a period of five years after being reintroduced or until viable offspring have been produced (whichever is the longer period)."

Pere David's Deer has not been assessed since 2016, and so it is perhaps time it was reassessed if reintroductions have been taking place.
 
Here's a few excerpts from that 2016 assessment:

"This species is listed as Extinct in the Wild. The captive population in China has increased in recent years, and the possibility remains that free-ranging populations can be established some time in the near future. When that happens, its Red List status will need to be reassessed."

"After decades of ex situ conservation, the species breeds successfully in captivity (Beck and Wemmer 1983). In China there are now fenced populations in Beijing, Dafeng, Shishou and Yuanyang."

And tucked away right at the end of the Population section:
"There are now four wild populations (not fenced) living in Hubei and Hunan provinces established by escaped individuals from Shishou Nature Reserve during severe flooding in 1998. The latest data from 2015 suggests that the wild population is about 600 individuals (M. Boyd pers. comm. 2015), surveys need to be conducted to assess the long-term viability of these populations."

Definitely sounds like a species in need of a reassessment. :p

The assessment can be found here: IUCN Red List of Threatened Species
 
A study from this year described the Lake Chilingali cichlid (Lethrinops chilingali) and stated that this species is assumed extinct in the wild. It remains to be kept in captivity and I saw this species in Chester Zoo this year. They breed them behind the scenes.

Going to add the northern spotted owl (Strix occidentalis caurina), which I've both seen and worked with, as while there is a (threatened) wild population in the States, the subspecies is functionally extinct (and on the road to complete extirpation) where I'm from.

Thought I would update the list with a one I forgot about:

9.) Charco Palma pupfish (Cyprinodon veronicae), ZSL Whipsnade Zoo
 
Minimal updates to the extinct in the wild category in today's IUCN red list update; 3 species of partula have sadly moved from EW to extinct (all historical extinctions, the most recent was lost from the captive breeding programme in 2016). One new species assessed as Extinct in the Wild: the pride of Burma (Amherstia nobilis), a mysterious tree that was only ever found once in the wild, in 1865 in what is now Myanmar.
