Crypturellus erythropus saltuarius Wetmore, 1950
Taxonomy & Nomenclature
Synonym/s: Crypturellus saltuarius Wetmore, 1950
Last record: 9 June 1943 (1980's?; 1990's? 2008?)
Laverde-R. and Cadena (2014:3) reported the existence of two vocal recordings of this species. Thus its conservation status, whether rediscovered or whether it was never really 'lost', is unclear.
Several reports of the continued existence of this species have been reported, and it may still survive, though in tiny numbers, as a specimen was apparently kept in captivity in the 1990's (Donegan et. al. 2003a,b; Hume & Walters, 2012: 18). However, its distinctiveness as a taxon has been questioned as well (Remsen et. al. 2006). Caution should be urged when considering this taxon either as valid and possibly extinct, or invalid. If it is considered invalid and yet is valid, conservation measures will most likely not be put in place to conserve this population. Thus a distinct species may go extinct as a result of confusion over it's taxonomic affinities. This would not be the famous 'Romeo Error', but an altogether different error. I shall therefore coin the term 'Invalid Error' to refer to this new error.
Magdalena River Valley, Colombia
Biology & Ecology
Only known from the holotype, an immature individual collected on the 9th of June, 1943:
"The only C. (e.) saltuarius skin shows has a lighter belly than other forms, more greyish wash on the breast and darker crown."
(Quoted from Remsen et. al. 2006)
One other specimen, collected in 1786, is currently unaccounted for and may have been lost (Hume & Walters, 2012:17).
