Link to BirdLife species factsheet for Rusty-necked Piculet

Rusty-necked Piculet Picumnus fuscus is currently listed as Near Threatened under criterion B1a+b(iii) on the basis that it occupies a moderately small range in which there is an ongoing decline in the area, extent and/or quality of its habitat.

The range map for this species has recently been updated and the species’s Extent of Occurrence is now estimated at 40,800 km2. This no longer approaches the threshold for Vulnerable under the B1 criterion, and suggests that the species is eligible for downlisting to Least Concern.

Comments are invited on this proposed category change and further information on this species would be welcomed, especially on the likely population size, estimated rate of population decline over a period of 13 years (estimate of three generations) and the impact of threats.

    A recent analysis of the effects of projected deforestation in Amazonia on bird species population trends (Bird et al. 2011) suggests that P. fuscus does not qualify for any category higher than Least Concern under criterion A4. For further information, please see the topic entitled ‘Input required on proposal to uplist a suite of Amazonian birds owing to predicted declines from projected forest loss’ (http://www.birdlife.org/globally-threatened-bird-forums/2011/10/input-required-on-proposal-to-uplist-a-suite-of-amazonian-birds-owing-to-predicted-declines-from-projected-forest-loss/).
