The Bald Parrot They are known only in some locations covering the lower basin of Madeira River and the upper basin of Tapajós River in the Brazil Amazon, more specifically in the Rio São Benedito (Field observations) and Cururu-acu River, both tributaries on the right bank of the river Teles Pires, himself a tributary of Tapajós.
There are several recent records of this new species from the micro-region of Madeira in the vicinity of Borba.

Since the species is currently known only from Two types of habitat and a relatively small area, it is unlikely that the population is much higher 10.000 individuals, so it is considered that it is near-threatened. It is likely to occur more records now that has been formally recognized as a species, and this may clarify its exact state.

Therefore, you suspect your decrease in population <25% durante tres generaciones.
