The greyish piculet (Picumnus granadensis) is a species of bird in subfamily Picumninae of the woodpecker family Picidae. It is endemic to Colombia. The greyish piculet is 9 to 10 cm (3.5 to 3.9 in) long and weighs 12 to 13 g (0.42 to 0.46 oz). Adult males of the nominate subspecies have a black crown and nape with small yellow tips on the feathers of the front and top and white spots on the rest. Their ear coverts are chestnut brown with a few white streaks, their cheeks off-white with blackish feather tips, and the sides of their neck gray-brown with white spots or streaks. Their hindneck and upperparts are grayish brown, often with an olive tinge. Their flight feathers are dark brown with yellowish green edges. Their tail is dark brown; the innermost pair of feathers have white inner webs and the outer two pairs a white stripe. Their chin and throat are off-white with blackish feather tips. Their underparts are dull white; the flanks sometimes have fine grayish streaks. Their iris is brown, the beak black, the bare skin around the eye gray-blue, and the legs gray with a green or blue tinge. Adult females are identical but with white spots on the whole crown and no yellow. Juveniles are duller and darker than adults and have more heavily streaked underparts. Subspecies P. g. antioquensis has grayer upperparts and more obvious gray streaking on their belly and flanks than the nominate.
