Link to BirdLife species factsheet for Amazonian Parrotlet

Amazonian Parrotlet Nannopsittaca dachilleae is listed as Near Threatened under criterion C2a(ii), because its population was suspected to number c.10,000 mature individuals, and was suspected to be in decline owing to habitat loss and degradation caused by selective logging, oil and gas extraction, mining, and associated road building and colonisation (Dinerstein et al. 1995). Its habitat, however, is relatively intact owing mostly to its inaccessibility, and the species has been described as locally common to very common (Juniper and Parr 1998, Forshaw 2006).

The species’s Extent of Occurrence is estimated at 134,000 km2, raising the question of whether the current population estimate is correct. If the population has been greatly underestimated, the species could be eligible for downlisting to Least Concern. However, recent observations suggest that the species is patchily distributed and very uncommon wherever it occurs (J. Gilardi in litt. 2010).

Up-to-date information is requested on this species’s likely population size, estimated population trend over 15 years (estimate of three generations) and the severity of threats to help in the assessment of its threat status.

    The following comments were received from Jamie Gilardi on 20 November 2010 during the preparation of this topic:

    I think this is one of those range map issues without a lot of basis in reality – a common phenomenon for parrots as it turns out. There really aren’t many places where this bird has been found, but if you draw a polygon around them all, sure, it’s a huge area. In fact, the bird is very uncommon even in places where it was first discovered, including Manu, Peru where I did most of my field work. In two field seasons, I never encountered the bird even though it was one of the sites where it was first seen.

    I contacted Charlie Munn who first saw it there and who worked with O’Neill on the initial description – he thought that the current status was about right, found in widely scattered localities, but not common at any. He didn’t think it was in need of a bump one way or the other.
