Plants and shit

Claudette Colvin, whose 1955 arrest for refusing to give up her seat on a segregated Montgomery bus helped spark the modern civil rights movement, has died. She was 86.

Her death was announced Tuesday by the Claudette Colvin Legacy Foundation. Ashley D. Roseboro of the organization confirmed she died in Texas.

Colvin was arrested months before Rosa Parks gained international fame before refusing to give up her seat on a segregated bus.

yo wtf is going on in skyrim

I’m the best to ever do it

Nobody saw that (best if said loudly)

No one’s ever done it like me

I could be President/they should make me President

Behold, a mere fraction of my power!

The public wants to be me soooooo bad

I’m an expert in (thing you just failed at)

How could this have happened to god’s favorite princess?

Nothing ibuprofen and a glass of water cant fix

Whereas the reality is far more like

No transphobes allowed, only transborbs.

Check out my stuff!

While looking at the little screech owl, I took a series of photographs and made this gif to illustrate the of the automatic grasping action of the talons.

The structure of bird feet is set up so that the foot automatically grasps when the ankle joint is bent.  

This automatic grip allow birds to sleep while perching, and for raptors clench/grasp prey as the leg is folded on impact.

The mechanism of the foot is ingenious…. there’s no muscle in there at all. 

The foot is powered entirely by a pulley system of tendons. 

Two tendons that run along the back of the leg, Flexor Digitorum Longus and Flexor Hallucis Longus are responsible for the automatic grasp. The former pulls the forward facing toes, and the latter pulls on the hallux, or back toe. 

I drew a schematic diagram of these two tendons here:

It’s particularly interesting in raptors.

Raptors swoop down on prey with talons/legs outstretched. The impact with the prey folds the raptor’s legs against its body, causing the talons to clench automatically, tearing into the prey. The automatic grip is strong enough to kill, and is what allows many hawk species to catch and kill other birds in midair.
