The common English name hornbeam derives from the hardness of the woods (likened to horn) and the Old English beam, "tree" (cognate with Dutch Boom and German Baum)..

The horns of the European bison point forward through the plane of its face, making it more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison, which favors charging.

Gains in forest land have resulted from conversions from crop land and pastures at a higher rate than loss of forest to development. However issues have been identified such as the continued loss of old-growth forest, [ 9 ] the increased fragmentation of forest lands, and the increased urbanization of forest land. [ 10 ]
Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core). Partial or deformed horns in livestock are called scurs.
Map of wood-filled areas in the United States, circa 2000 [1]. In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2]
True horns are found mainly among: Ruminant artiodactyls. Antilocapridae ; Bovidae (cattle, goats, antelopes etc.). Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones.

Using an estimate of approximately 37 million people in Mexico, Central and South America in 1492 (including 6 million in the Aztec Empire, 5–10 million in the Mayan States, 11 million in what is now Brazil, and 12 million in the Inca Empire), the lowest estimates give a population decrease from all causes of 80% by the end of the 17th ...
Despite their unpalatable appearance, horns of plenty are edible and choice. [ 6 ] [ 4 ] According to a Portuguese study, 100 grams of dried C. cornucopioides contain 69.45 g of protein , 13.44 g of carbohydrates (mostly mannitol , a sugar alcohol ) and 4.88 g of fat, amounting to 378 calories .
