Hook bill

Slaty flowerpiercer (Diglossa plumbea) in Costa Rican Cloud Forest. Flowerpiercers drink nectar from flowers, but they don't have a long bill to access the flower from the front - they use their sharp pierced bill to poke a hole in the side of the blossom and they collect the nectar that drains out in their lower beak - thus depriving the flower of being pollinated.
