sika

Sika commonly refers to two distinct subjects: the sika deer, a deer native to East Asia, and Sika AG, a Swiss multinational company known for construction chemicals and sealants.

The sika deer (Cervus nippon) is a medium-sized deer native to East Asia, including Japan, Korea, and parts of China. It has a variable coat; fawns are spotted and adults may be darker. Males have antlers; females do not. They inhabit forests and brush near water and feed on grasses and leaves. They breed in autumn, producing one to three fawns after a gestation period of about six to seven months. Sika deer have many subspecies and have been introduced in Europe, North America, New Zealand, and elsewhere, where they can compete with native wildlife or affect local ecosystems.

Conservation status varies by region. Some native subspecies are rare or threatened, while introduced populations can be abundant and are often subject to management. Hybridization with other deer occurs in some areas, and the species is hunted for sport or meat in parts of its range.

Sika AG is a Swiss multinational company founded in 1910 and headquartered in Baar. It specializes in chemical products for construction and industry, including adhesives, sealants, waterproofing systems, and concrete additives, and operates globally through subsidiaries and distribution networks.
