Diglossa albilatera
The White-sided Flowerpiercer (Diglossa albilatera) is a diminutive yet striking songbird belonging to the Thraupidae family, closely related to the diverse group of tanagers. Measuring approximately 11-13 cm (4.3-5.1 inches) in length and typically weighing between 9 and 13 grams, adults present a glossy, deep black plumage that contrasts sharply with prominent, clean white flanks - the defining feature that gives the species its common name.

Primarily inhabiting humid montane evergreen and cloud forests, as well as forest edges, often found in dense understory. It thrives at high elevations, typically between 1,500 and 3,000 meters (4,900-9,800 feet) above sea level.
Primarily consists of nectar, obtained through piercing flower bases, supplemented heavily with small insects and arthropods. Small fruits may also be consumed opportunistically.
White-sided Flowerpiercers are diurnal birds, generally observed singly or in pairs, though small aggregations may form at highly productive floral patches. Their signature foraging behavior, nectar robbing, involves using their specialized hooked bill to puncture the base of flower corollas to a...
