The Attwater's Prairie Chicken
(Tympanuchus cupido attwateri)...
- is not actually a chicken. It's a grouse.
- is indeed endemic to Texas.
- isn't extinct in the wild, but is very close to it. The short mentions some 1000 left in the wild. Now there's less than 100, on three small refuges in Texas. It represents 0.2% of the original habitat range.
- has been successfully bred in captivity. The Houston Zoo runs a captive breeding program at NASA's Johnson Space Center. The short mentions that at that time, they hadn't been able to pull it off yet.
http://www.houstonzoo.org/protect-animals/texas-conservation/attwaters-prairie-chicken/ (http://www.houstonzoo.org/protect-animals/texas-conservation/attwaters-prairie-chicken/) - was decimated by what usually gets endemic species: habitat loss, introduced species, changing range management. Good livestock grazing practices will leave good habitat for the birds.
Fun! :clap:
