The only other ‘‘oceanic’’ woodpecker was the flicker of Guadalupe Island, off western Mexico, some 250 km from the mainland. Long considered an endemic subspecies, Colaptes auratus rufopileus, it
became extinct about 1906. Reanalysis of the specimens did not support subspecific validity, although the species had recolonized the island by 1996

I think Paul Sweet et al might have missed out on following up on one detail, mentioned by themelves (in that 2001 Paper):
"Ridgway (1876) also mentioned a pink wash on the rump as a character for the island race, but we were unable to find a consistent difference in rump color and did not investigate that trait further." [OD here)]

Red pigments are the one pigment that fades (if exposed to sunlight) more rapidly than other. For exemple in Sweden we have a unique specimen of Bullfinch, described as a "Loxia Flamengo"* by Sparrman 1786, that was pinkish all over. Se the plate of it here. Today, the specimen, housed in the collection of the Natural History Museum in Stockholm, looks like a true albino!

Thereby I would´t assume there truly was a "pink wash on the rump" on Ridgway's female specimen of "rufopileus". Even if there´s no trace of it today. This would, of course, also apply on the reddish "bright tawny forehead".

For what it´s worth.
