A medium-sized flowerpiercer of humid Andean cloud forest and forest edges from Colombia south to Bolivia, white-sided flowerpiercers have distinctive white flank patches contrasting with dark grey-blue plumage. Like all flowerpiercers, they use their sharply hooked and slightly upturned bill to pierce the base of tubular flowers and steal nectar without pollinating — earning them the reputation as nectar thieves. Found at elevations of 1,500–3,500 meters, they are commonly encountered in Andean gardens and forest edges.
