Some of the Cerrado species included in the PNAS study are:
- Kaempfer’s woodpecker (Celeus obrieni), a charismatic red-headed woodpecker. First recorded in 1926, Kaempfer’s woodpecker was believed extinct until 2006. Its population is estimated at fewer than 6000 (perhaps much fewer) individuals, and it is classified “vulnerable” on the IUCN Red List.
- The Blue-eyed ground-dove (Columbina cyanopis) was also rediscovered, as recently as 2015, after being thought extinct. Fewer than 250 individuals are believed to survive. It is classified “critically endangered” on the IUCN Red List.
