Hatchlings threatened by animals brought by people.
The Wandering Albatross has the longest wingspan of any bird in the world. This extraordinary wingspan lets them spend most of their lives in flight. The exception is when they go into breeding. That is when they move to the slightly warmer islands than their native habitat in the Antarctic Ocean. On the islands, they lay eggs and raise their hatchlings. However, their numbers have declined because those eggs and hatchlings are attacked by pigs and other animals that people brought to the islands.

Birds caught on fish hooks?!
Fishing is the main cause for their disappearance. The squid or fish bait on fish hooks accidentally lures the Wandering Albatross to take a bite, only to swallow the hook and drown in the ocean. Widespread damage is caused by fishing because of the heavy fishing boats that spread lines and lines of fish hooks throughout their habitat. Some fishing boats are taking measures to prevent birds from accidentally getting caught in their fish hooks, but the population of Wandering Albatrosses continues to dwindle.
