What are the difficulties faced by the arctic tern while travelling?

The Arctic tern faces several difficulties during its migration, which spans about 71,000 kilometers between breeding grounds in the Arctic and wintering areas in the Antarctic. These challenges include extreme weather conditions, such as storms and harsh temperatures, which can disrupt their journey. Additionally, they encounter predators and limited food availability during long stretches over open ocean. Human impacts, such as habitat loss and climate change, further complicate their migration and survival.
