arviinnin

Arviinnin, also known as Arctic tern, is a small seabird belonging to the family Sternidae. It is one of the most widespread and abundant birds in the world, with a global population estimated to be around 1.5 million individuals. The Arctic tern is known for its remarkable migratory behavior, traveling over 50,000 kilometers annually between its breeding grounds in the Arctic and its wintering grounds in the Antarctic.

The Arctic tern is characterized by its long, narrow wings and a distinctive white body with a black cap and black wings. It has a long lifespan, with some individuals living up to 30 years. The bird feeds primarily on small fish and insects, which it catches by diving into the water from the air.

The Arctic tern plays a crucial role in the ecosystem as a predator and as a prey species for larger birds of prey. It also serves as an indicator species, helping scientists monitor changes in the environment and climate.

The species is listed as Least Concern on the IUCN Red List, but it faces threats from habitat loss, pollution, and climate change. Conservation efforts focus on protecting its breeding and wintering grounds, as well as reducing human impacts on its migratory routes.
