Taxonomic note
Waved Woodpecker Celeus undatus and Scaly-breasted Woodpecker C. grammicus have been lumped as Waved Woodpecker C. undatus, following the finding that there was no genetic or morphological differences between representatives of the two (Sampaio et al. 2018), and the previous observation that the calls were extremely similar (Benz and Robbins 2011).

Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996). Poorly known and unobtrusive, this species also occurs in areas difficult to census (Winkler and Christie 2019).
Trend justification: Prior to the two species being lumped, those subspecies grouped under C. undatus were projected to lose 24.1-27.6%, and those under C. grammicus were projected to to lose 15.8-18.4% of suitable habitat within its distribution over three generations (15 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It was noted that the former group were relatively tolerant of habitat degradation hence was considered likely to decline by less than 25% over three generations. In combining the two former species the estimated rate from the previous models is overall lower than 25%, but there is a need to update the underlying data. For the present assessment the suspected current and future decline for Waved Woodpecker is <25% over three generations.
