Steinadler

A Steinadler (pl. Steinadler; pron: SHTYN-aad-lər, Grimm: STYN-ad-lər; Germ. Stein "stone" + Adler "eagle") is a hawk-like Wesen (though in German their name means Golden Eagle).

Farley Kolt is a Steinadler who tricked two Schakale into shooting each other. He was arrested, and afterwards, told Nick about the coins, and about his relationship with Marie Kessler. Marie left Farley to take care of her sister's son, who was Nick. He assisted Nick and Hank when they tracked Soledad, realizing he killed Nick's parents. Kolt stole the coins from Renard after Soledad was apprehended. Nick later then got back the coins from Kolt.

Characteristics
When woged, Steinadlers gain muzzle-like face and a beak-like nose. They have sparse feather-like hair all over their body, while the hair on their heads is a silvery-grey, usually in the form of a tall flattop. Their eyes are an extremely pale yellowish-green color. Like a few Wesen, they can localize their woge in their eyes without altering the rest of their body.

Steinadlers are renowned for their exceptional vision. Their superior vision is a result of having five times more visual sensory cells per millimeter of the retina than humans. They also have special colored oils in their eyes that reflect certain wavelengths of light. These special ocular biologic factors endow them with near perfect night vision, and a whole host of other ocular abilities.

Steinadler are incredibly fast creatures, appearing as a blur when they run, They don't appear to be superhumanly strong, but appear to be durable creatures.

A Steinadler Knife is used by Grimms to kill only Steinadlers. The blade is smithed from platinum and dipped in nightshade. A single stab to the heart is often enough to dispatch them.

Behavior
The Steinadler are known for their ability to pokerfacedly exhibit simultaneously friendliness and sternness, so it is impossible to tell whose side one is on. The ability to sternly influence others as though they were subordinate friends makes the Steinadler excellent military figures. They have a reputation for being heroes and adventurers as well as having high intellect and good intuition.

''The Steinalder has five time more visual sensory cells per millimiter of retina than do humans. They also have colored oils in their eyes that refract certain wavelengths of light. This intensifies certain colors at the expense of others.''

''The visual ability of the Steinadler is legendary. Adaptations to night vision include larger eyes and large numbers of closely packed visual rods and cones.''

The distinctive brow ridge physically protects the eye from wind, dust and debris, and shields it from excessive glare.
