Scientists are currently tracking a Tristan Albatross- a critically endangered species-which has made a groundbreaking expedition from its home on Gough Island in the South Atlantic. Recently a research vessel off the central California’s coast spotted a waved Albatross, marking only the second recorded sighting of this species north of Central America.
The yellow-billed bird with black button eyes- which can have a 2.4-metre wingspan and spends much of its life airborne over the ocean- is at the center of a mystery.
Researchers are wondering about this “vagrant” bird travelling far outside its typical range. It was spotted 37 kilometers off the coast of Point Piedras Blancas, roughly midway between San Francisco and Los Angeles.
Scientists have revealed that seabirds such as albatrosses, travel vast distances in search of food. On rare occasions, an individual routine may lead them to end up far away from home-sometimes even in the wrong hemispheres or exceptionally in the wrong ocean.
While a factor such as food scarcity could prompt a bird to wander, a single sighting might simply be a “fluke” misadventure.
According to the American Bird Conservancy, the species’ range is restricted to the tropics, as it nests on lava fields and strewn rocks and sparse vegetation.
An analysis suggests that if multiple birds are seen in California, it could indicate they are being pushed northward by environmental factors.
For example, five species of Booby are now more common in California in the wake of rising warm temperatures and marine heatwaves.
The species is already under threat from invasive mice on Gough Island that eat their chicks alive. Risk factors increase when the population is forced to travel thousands of extra kilometers in search of food. The ultimate consequence could be total colony collapse, driven by exhaustion or increased encounters with commercial fishing boats.
