Additions and updates to the list of specimens of Imperial Woodpecker Campephilus imperialis (Gould, 1832), including genetic analysis of a putative clutch of eggs

Summary. We present an addendum to the list of known specimens of Imperial Woodpecker Campephilus imperialis published by Brown & Clark in 2009. The addendum adds a total of 31 specimens, comprising 15 mounts, ten study skins, three skeletons, two skulls and one not extant specimen, bringing the total number to 189 specimens. It also offers clarification of some of the records presented in Brown & Clark, as well as revisions of several specimens previously registered as C. imperialis but later found to be of other species. The latter includes a putative clutch of Imperial Woodpecker eggs, which was found via genetic analysis to belong to Burrowing Owl Athene cunicularia.
