The Stone Forest or Shilin is a notable set of limestone formations located in Shilin Yi Autonomous County, Yunnan Province, People's Republic of China, near Shilin approximately 120 km (75 mi) from the provincial capital Kunming. The tall rocks seem to emanate from the ground in the manner of stalagmites, with many looking like petrified trees thereby creating the illusion of a forest made of stone. Since 2007, two parts of the site, the Naigu Stone Forest (乃古石林) and Suogeyi Village (所各邑村), have been UNESCO World Heritage Sites as part of the South China Karst.

Geese fight during the annual Geese Fight Day in the northern Serbian village of Mokrin, some 160km (100 miles) from Belgrade February 22, 2015. Every year in the last week of February, goose fights are held in the northern Serbian village of Mokrin. Left alone, male geese, or ganders, are unlikely to fight each other, hence why females are brought along for whose affections the ganders then fight until one or the other gives up.
