Blood is mostly liquid, with numerous cells and proteins suspended in it, making blood thicker than pure water. The average person has about 5 liters (more than a gallon) of blood. A liquid called plasma makes up about half of the content of blood.
Feet and Beak. Like other birds in the raptor group, owls of all species use their beaks and talons to defend themselves. An owl's feet are equipped with particularly long, sharp and curved claws, which he can dig into an adversary and use like hooks to tear and rip at flesh.wls can't always successfully defend themselves from other animals, particularly their prey. Great horned owls, for example, are often found either dead or injured as a result of would-be prey like skunks and porcupines fighting back.
Bubo virginianus. The Great Horned Owl is one of the largest, most powerful, and widespread raptors in North America. Its breeding range extends from central Alaska across Canada to Newfoundland south throughout the Americas to Tierra del Fuego (A.O.U. 1983).TATUS: The status of the Great Horned Owl in Texas appears to be very good. It is common throughout the state and can survive in a variety of habitats. BBS data show a non-significant increase both in Texas and in the United States as a whole for the period 1966 to 1996 (Sauer et al. 1996).
