A REMOTE island within the Southern Indian Ocean has been overrun by vicious “zombie mice” who come out of their droves at evening and eat birds alive.
Over one million rodents are set to be exterminated when six helicopters swarm Marion Island to drop 550 tonnes of poison on their heads.

Albatross, a fowl that calls Marion Island home, are repeatedly killed by the vicious mice.
They transfer in small packs beneath the quilt of darkness and swarm birds’ nests the place their chicks are sleeping.
After deciding on their victims, the mice perch on the birds heads to gnaw away at their flesh, scalping them alive.
The tormented birds ultimately develop weak and drained from a scarcity of sleep.
They typically get sick, possible growing infections from the grotesque assaults, and die.
Disturbing evening imaginative and prescient footage taken on the island reveals the “zombie mice” in motion.
An picture of 1 mouse reveals it perched on the top of a fowl which is frozen utterly nonetheless in terror, because the rodent chews away at its scalp.
The birds haven’t developed defence mechanisms to guard themselves in opposition to the predators, which aren’t indigenous to the island, specialists say.
The mice will repeatedly attack chicks from dozens of various fowl varieties on the island.
Now, after years of torment on the island, the South African authorities and its accomplice organisations have devised a plan: The Mouse-Free Marion undertaking.
Using army precision and an unlimited effort with a funds of £19.6million, they hope to eradicate the mice totally.
Marion, midway between South Africa and Antarctica, would be the greatest island but the place such a manoeuvre has been tried.
As many as six choppers, flown by extremely expert pilots will drop 550 tonnes of poisoned bait for the mice in steady shifts till all the island is roofed.
Andrea Angel, albatross process pressure chief from Birdlife South Africa, instructed nine.com.au: “I do not assume I’ve ever seen something so grotesque.
“They’re scalped. The mice are always on the birds at evening – on their heads, of their eyes and crawling throughout them.
“The chicks can barely transfer. They’ve received these wounds which can be festering and open on their stomach.
“It is harrowing to observe and it will die. It is heartbreaking.”
Angel is one among a bunch of scientists who reside and analysis on the island, generally for as much as a yr at a time and who dubbed them “zombie mice”.
No different people reside amongst the mice.
She can inform which albatross have been attacked in a single day earlier than she even will get near them.
While most are energetic, “flapping their wings” or “practising to fly”, those that’ve been focused are “simply sitting there, doing nothing”.
Angel says by this level they’re so exhausted from attempting to flee the mice they’ve run out of power and quit.
Once the birds ultimately die, the mice return to feed on their corpses.
Deadly invaders
The mice have been by accident delivered to Marion within the early 1800s, arriving by way of ship with seal hunters.
While the creatures on Marion Island used to coexist fairly peacefully, as temperatures warmed within the 2000s extra mice have been in a position to survive the winter.
They multiplied quicker and quicker, and have become ravenous of their greater numbers in the course of the winter.
But of their desperation for meals, the rodents began to attack each grownup and child albatross as they rested.
The phenomenon of mice consuming seabirds has been recorded on solely a handful of the world’s islands.
Usually mice survive on a food plan of crops like grains, fruits or seeds however do additionally eat small animals like bugs.
The diets of Marion’s “zombie mice” is very uncommon.
One professional concerned within the undertaking stated the specialist group will solely have “one probability” to eliminate the mice.
If even a tiny portion of the island is missed within the bait drop and only one pregnant mouse survives, the colony may very well be regenerated.
The drop should additionally occur throughout winter when they’re at their most energetic and looking for meals.
The undertaking will cost a fortune – even the bait alone prices tens of millions.
And flying the choppers to this point south in the course of the winter comes with its personal threat for these concerned.
‘One shot’
Nini van der Merwe, spokesperson for BirdLife South Africa (BLSA), stated: “The majority of mice assaults occur in winter time, due to meals shortage on the island.
“And that can also be why the eradication should occur at winter so the mice might be extra more likely to go for the bait.
“We actually need the climate to be on our facet.
“You have very small home windows when situations are optimum for flying and distributing the bait.
“You get one probability. There isn’t any do over. It’s an excessive amount of money and it takes an excessive amount of time.”
Speaking concerning the mild albatross who name Marion home, Angel stated it’s clear how devastated the birds are when the mice kill their young.
“When you see a chick die due to these mice assaults … what these mother and father undergo, it drives you to tears.
“You can see the despair, the care, the love they really feel for these chicks.”
The island is a uncommon undisturbed home for the majestic birds, but in addition homes 29 different species of fowl.
Macaroni penguins and seals additionally name the distant island home.
The mice feed on different seabirds in addition to albatross, and invertebrate creatures, disrupting the islands’ total ecosystem.
Scientists are planning to execute the mammoth Mouse-Free Marion Project in 2027.
