Taxonomy

Taxonomic note
Deconychura longicauda, D. typica and D. pallida (del Hoyo and Collar 2016) were previously lumped as D. longicauda following AOU (1998 and supplements), SACC (2005 and updates), Sibley and Monroe (1990, 1993) and Stotz et al. (1996).

Population justification: The global population size has not been quantified, but prior to being split from D. pallida, this species was described as 'uncommon' (Stotz et al. 1996).

Trend justification: Prior to being split, this species was suspected to lose 13.7-15.4% of suitable habitat within its distribution over three generations (12 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). The amount of habitat loss over the range of the newly-split D. longicauda is not known, but habitat loss has been less intense over the past three generations within the range of the newly-split D. longicauda than in other parts of the pre-split species’s range.
