White-sided Flowerpiercer

O furapétala-de-flancos-brancos (Diglossa albilatera) é um furapétala médio de florestas nubladas andinas úmidas e suas bordas, desde a Colômbia até a Bolívia. Apresenta manchas brancas distintas nos flancos que contrastam com a plumagem cinza-azulada escura. Como todos os furapétalas, usa seu bico ganchudo e ligeiramente voltado para cima para perfurar a base de flores tubulares e roubar néctar sem polinizá-las — ganhando a reputação de ladrões de néctar. Ocorre entre 1.500 e 3.500 metros de altitude e é encontrado em jardins andinos e bordas de mata.
