An Oxpecker is an African bird which rides around on the backs of herbivorous animals, eating ticks, fly larvae and other parasitic insects. While this is beneficial to the animals, the bird will also peck holes in the animals' hides to drink their blood. I recently discovered the word "oxpecker" while playing PC Scrabble.
