The Flowerpiercers are small birds in the Tanager family that have the upper tip of the bill curved down, allowing them to pierce flowers from the base and drink their nectar, hence their name. Their very short bill do not allow them to drink nectar like a hummingbird does, by inserting the bill into the flower, so they do not pollinate flowers. Instead, they used their bill to open up a hole at the bottom of the flower, and drink the nectar that dips from it. Both the Masked and the Black Flowerpiercer have a similar shape and size, however their colors are pretty different. The black mask with bright red eye of this species is unmistakable.
