Moving on

Yes, I took down the last post. Time to move on.

So, been pretty busy with classes lately and trying to keep myself busy. Today was Comparative Animal Wet Lab. They brought in a bunch of dead/decaying/half frozen birds and marine animals. We had a baby dolphin, a porpoise, a river otter, a beaver, couple swans, a few Canadian geese, a few hawks, a few owls, pigeons, wild turkeys, rabbits, squirrels, opossums... basically whatever was at the wildlife hospital and died. It was intensive anatomy, like the horses or dog, more like you cut it open and say "ooo, look at this." The marine animals looked like some gruesome murder scene after everything was dissected out. Some of the more memorable bits: woodpeckers store their tongues on the top of there heads so when you pluck off some feathers and pull its tongue out, you can see it move at the top of the head, neat;

beaver fingers look just like small human fingers, only webbed; the dolphin brain is larger and more convoluted then the horse, ruminant, and dog brain; the upswing of birds wings is the action of pectoral muscles, not back muscles like you might think; owls have really big ear holes; turkey pectoral muscles look just like the meat you by in the store.

Baby horses tomorrow!

I think I am anatomically challenged and I need some help imagining the woodpecker. I take it they have long tongues that they stick in the holes that they peck in the wood... and how we store our tongues in our mouths, woodpeckers store theirs up in their heads?

And what tools do you use to pull out a woodpecker's tongue?

They have very long tongues that they use to grab bugs out of the holes they make. The tongue is in the beak, travels under the head, to the back of the neck, and then up over the brain case just below the skin and inserts in the bird's right nostril. So, it's so long, it has to go somewhere. Instead of rolling it up, they keep it on the top of their head.

All the animals were dead, so we open the woodpecker's mouth and pulled out the tongue with forceps. With all the pulling the tongue was eventually stuck outside the beak, so you had to jam it back in to see it move under the skin.
