The hatchery of migratory penguins can be magical places , full of fluffy bird and doting parents . But things are less picturesque when you add volcanic ash to the mix . A vent on the northernmost island of an archipelago in the South Atlantic Ocean has been puke ash and smoke since March , threatening one of the largest colonies of penguins in the world , according to a new study .
Zavodovski Island , one of the South Sandwich Islands , is uninhabited by mankind , but it is home to more than 1 millionchinstrap penguins , harmonize to the British Antarctic Survey ( BAS ) . BAS researchers found the volcanic eruption via satellite imagery and fishermen from nearby South Georgia were capable to photograph ash tree blowing eastward across the island over penguin - nesting ground .
Volcanic ash threatens an enormous colony of chinstrap penguins
“ We donꞌt be intimate what impact the ash will have on the penguins , " Peter Fretwell , a geographer with the BAS , say in a statement . " If it has been grueling and far-flung it may have a serious consequence on the population . " [ Charming Chick Photos : Antarctica ’s Baby Penguins ]
The chinstrap penguin(Pygoscelis antarctica ) stand up about 30 inches ( 75 centimeters ) tall and eat mostly krill ( tiny crustaceans ) . These penguins are abundant throughout the sub - Antarctic realm , and there are at least 8 million in the wild , harmonize to theInternational Union for Conservation of Nature .
The penguin pasture at ocean from March until November , when they return to their colonies to breed . When the irruption began in March , some straggling penguins may have still been molting , shedding erstwhile feathers and growing newfangled ones , and were ineffective to go away the island , said Wayne Trivelpiece , a life scientist with the National Marine Fisheries Service who has studied penguins for 40 geezerhood .
There is grounds of anterior volcanic activity on Zavodovski Island , grant to the BAS , but the extent of that volcanism and its effect on wildlife on the outside island are unknown . Two expeditions are planned later this class to evaluatedamage from the eruption , Fretwell sound out .
But the independent effects of the clap , Trivelpiece say , wo n’t be known until the penguin return to the island , where 10 to 15 percent of the world ’s chinstraps nest . " If the ash cut across everything , that will make a difference , " he say , " That ’s not go to be in effect terrain to lay eggs in . "
Ultimately , like the BAS , Trivelpiece is bring a hold off - and - see approach in assessing the effects of the eruption by Mount Curry on the island ’s penguin universe . He said the ash could be mess up out to sea , or the " very adaptable " chinstraps may find substitute nesting ground .
" We donꞌt really have it away , " Trivelpiece told Live Science . " We ’d just be guessing . "
