Joutsenista

Joutsenista, also known as the Whooper Swan, is a large waterbird species belonging to the family Anatidae. It is native to the northern hemisphere, with populations found in Europe, Asia, and North America. The Whooper Swan is characterized by its long neck, long legs, and a distinctive white body with a black head and neck. It is one of the largest species of swan, with adults typically measuring around 150-170 cm in length and having a wingspan of up to 270 cm.

The Whooper Swan is a migratory bird, with most populations breeding in the Arctic tundra and wintering in more temperate regions. Its diet primarily consists of aquatic plants, but it may also feed on small animals and insects. The species is known for its distinctive "whooping" call, which is used for communication and courtship displays.

The Whooper Swan is listed as Least Concern on the IUCN Red List, although some populations have declined due to habitat loss and hunting. Conservation efforts are focused on protecting breeding grounds and wintering areas, as well as addressing threats such as pollution and climate change. The species plays an important role in its ecosystems, both as a predator and a scavenger, and is also a popular subject for birdwatching and photography.
