Great Slaty Woodpecker Mulleripicus pulverulentus. Cambodia, January 2013, by Neil Bowman. Presuming that the Imperial Woodpecker of Mexico is sadly extinct, this SE Asian species is the largest woodpecker on the planet at around 50cm in length.
Wells of Yellow-belled Sapsucker Sphyrapicus varius in a palm tree. These precise holes are created in rows by the birds to access sap, an important food source in both breeding and wintering areas. Photo by Gerard Gorman, Bay of Pigs, Cuba, March 2014.
