We report observations of a Glossy Flowerpiercer (Diglossa lafresnayii, Thraupidae) using and maintaining sap wells on three shrubs (Asteraceae: Baccharis arbutifolia) on the east slope of the Ecuadorian Andes. The flowerpiercer rotated among shrubs in a trapline fashion, licking and drinking sap and dragging its hooked upper mandible, and possibly also its lower mandible, along the wounds in the Baccharis trunks, presumably to keep sap flowing. This represents, to our knowledge, the first description of sap well use and maintenance in the Thraupidae.
