The exact number of albatrosses left in the world depends on the species and the time of the year. According to the International Union for Conservation of Nature (IUCN), some species of albatrosses, such as the wandering albatross (Diomedea exulans), have a global population of around 25,000 mature individuals. On the other hand, some species, such as the Amsterdam albatross (Diomedea amsterdamensis), have a global population estimated at only 100 to 180 mature individuals.
It's important to note that these numbers can fluctuate over time due to various factors such as habitat changes, breeding success rates, and human activities. Conservation efforts are ongoing to protect albatross populations and their habitats to ensure their long-term survival.
