Similar species

Male White-sided Flowerpiercer can be confused with male Glossy Flowerpiercer which is less slaty but has a greyish-blue shoulder-patch. In parts of Colombia, where the Black Flowerpiercer has a greyish-blue shoulder-patch (as in Glossy), this is another species to keep in mind.

Female Rusty Flowerpiercer has pale-fringed tertials. It may also be paler with slight yellowish wing bars and have a pale lower mandible base. It lacks the (concealed) white flanks.


South America: found in Venezuela, Colombia, Ecuador and Peru.

There are 4 subspecies[1]:

  • D. a. federalis:
  • Coastal cordillera of northern Venezuela (Aragua to Miranda)
  • D. a. albilatera:
  • D. a. schistacea:
  • Andes of extreme south-western Ecuador to north-western Peru (Cajamarca)
  • D. a. affinis:
  • Highlands of north-central Peru (above Río Utcubamba) to Cuzco


Humid overgrown forests and clearings, particularly areas with flowering vines.



Their diet consists almost entirely of nectar and probably some insects too.

They forage singly or in loose pairs; sometimes a family group of three. They sometimes join mixed species flocks.
