Yep, Woodpecker Tongues are totally bad ass. They wrap around their head and can extend out 3 times the length of their beaks using a mechanism called the Hyoid Apparatus. The tongue itself has a bony point on the end covered in backward facing barbs in order to harpoon their prey. And if they miss, the tongue is covered in sticky saliva which can also help snag any prey. They also have a listening device in their tongues, called the Herbst Corpuscle, which allows them to sense vibrations.
