A pintail from central Colombia, Anas georgica niceforoi, may be extinct. First described in 1946, this subspecies of the yellow-billed pintail has not been reliably recorded since 1952. Despite the fact that it appears to have been well known to local shooters, only a small number of naturalists ever saw it.

Subspecies niceforoi, described in 1946, had been considered to be extinct by 1956, but was reportedly rediscovered in Jan 2003

A very interesting paper. The question is what happened to its habitat and its population after 2004. 40 birds are damned less to guarantee a longer survival (cf Madagascar pochard which has apparently a better conservation programme than the Niceforo's pintail).

Comment by Gary Styles in 2008 (automatic translation) Unfortunately, in an article published in a magazine Colombia recently, the authors (and editors) did not have this precaution, and specimens based on the assumption that a rediscovery extinct subspecies (Anas georgica niceforoi) were be another subspecies (A. g. spinicauda) and known in the south and not threatened globally. Post is good, but with due care, for both correct errors one could be "immortalized"! www.asociacioncolombianadeornitologia.org/wp-content/uploads/2013/12/notaeditor1.pdf
