The tongue by far is the most amazing adaptation.  Just from the length alone and how it curls back into the head is unexplainable, however, necessary when you think of what it does and what it is used for.  Also, the barbs and brush like structures at the end of the tongue were rather exciting to learn about.

The most fascinating adaptation to me is the woodpecker's tongue.  I knew woodpeckers had longer than average tongues, but didn't realize how long.  Also, the barbs or brushes at the tip of the tongue, and the fact that the tips can regrow when worn out was new to me.  We have seven species of woodpeckers living in the area surrounding our home, so we see and enjoy a lot of woodpecker activity, but these close-up videos and explanations of the woodpecker's adaptations are making me appreciate our woodpecker neighbors more than ever.

I was amased at the length of the tongue and the different structures of the tongue to help the get food! I always thought they did most of the food gathering with the pounding of the bill but see now how they all work together!

The different structures at the end of their tongues is something I wasn’t aware of, and that’s quite fascinating. I loved seeing the way the harpoon-type structure can snag larvae to drag them out.

That incredible tongue.

Woodpeckers are truly amazing birds. Their bills can chisel away live wood, their super long tongues can penetrate deep inside crevices and snag larvae with their specialized tips. Woodpeckers are both colourful and matched incredibly to the task.

I am impressed by those tongues!

I was amazed to learn about the stability provided to the woodpecker by it’s zygodactyl feet and rigid tail. I will definitely look differently at a woodpecker the next time I see one!

How the long tongue can wrap around the skull

All of it! Their tripod tail, toes that can extend, reach and grip like monkeys, amazing bill and fishing tongue. AS a bonus, they have pleasing vertical silhouettes and art-worthy plumage.

The different tongue tip structures!

My favorite woodpecker adaptations are their zygodactyl feet and their long tongues.  It was interesting to learn that the woodpecker will move one toe sideways to give it more security while pecking on a tree.  Their long tongues are impressive, but the fact that they have added adaptations, like the addition of hair-like features, barbs, or brushes that help the woodpeckers grasp their prey is a marvel!

Those tongues are facsinating!

I like the tail on the pileated woodpecker who visits my suet feeders. I enjoy watching him plan his attack on his feeder of choice, using his tail for support.

I didn't know about the fact that woodpeckers use their tail feathers like a kickstand to stabilize them on a tree, and I'm amazed that their tongues are so long and barbed!

A woodpecker's tail allows it to balance itself close to the tree while working at a decided task. They are well-equipped to seize their food with unique tongues.

I have grown up hearing people discuss woodpecker beck's and how they use them...but the tongue is the real surprise!

All of the adaptations; bill morphology, tongue morphology, leg+feet morphology; sexual dimorphism, all play a role in the success of this group.

No question. Those tongues!  Before the explanation about tongues, i would have said their adaptations for pecking, but the tongues win!

I think their tongues are the most amazing adaptation. I remember learning about this in a lecture from a ranger in Yosemite National Park years ago. It was the beginning of my fascination with these remarkable birds.

Fascinating how woodpeckers have adapted to meet their needs.

It has to be the tongue and the different ways in which they are structured, depending on their diet.

The tongues are amazing.  I wonder whether the tongue when retracted acts as a shock absorber?  It is amazing to me as a neuroscientist that their brains can withstand the drumming!

My favorite woodpecker adaptations are their tongues, the length and structure of tongues are really amazing.
