By learning from previous threats how to protect Critically Endangered species. Hundreds of species of bird that have been wiped out by human activity in the modern era. Here are just a few species that illustrate the major threats still facing birds today. Can you solve the riddle of the Mysterious Starling? Many Pacific island reed-warblers are highly threatened by invasive species, and some have already gone extinct, such as this rangy looking bird from the Northern Mariana islands.
The Pagan Reed-warbler was until recently considered a sub-species of the Guam Reed-warbler Acrocephalus luscinius , an extinct bird from the island of Guam which was wiped out in the s by introduced plants, animals and habitat degradation. A decade later, the Pagan Reed-warbler followed it into the history books. Newly-recognised as a distinct species in , this glossy, scarlet-and-black insectivore has the unwanted distinction of becoming the first avian extinction recorded in the Galapagos.
There was also a South Island Piopio Turnagra capensis , which became extinct by for much the same reasons. This pink-eyed forest dweller was a once-abundant species endemic to Lord Howe Island, Australia. Last heard from in , none were found on a survey eight years later. A Hawaiian honeycreeper with a spectacular bill, this insectivore would use its bill to probe through tree bark in search of arthropods, also using it to collect nectar from flowers.
Formerly one Extinct species, it is now recognised as one of three separate Extinct species, all of which disappeared as a result of deforestation.
It was also presumably susceptible to avian malaria, an introduced disease carried by mosquitoes. Sadly the Laysan is long gone after introduced domestic rabbits ravaged all the vegetation on the island — including the nectar sources the honeycreeper fed on. In the s, the island of Laysan was battered by a strong storm and the bird was never seen again. All species belonging to the Hawaiian genus Moho became extinct as a result of man-made threats: deforestation, competition from introduced predators and hunting — their much-sought feathers used to make capes for Hawaiian nobility.
Another thing they share: All 23 were thought to have at least a slim chance of survival when added to the endangered species list beginning in the s. Only 11 species have been removed due to extinction in the nearly half-century since the Endangered Species Act was signed into law. Around the globe, some species have been documented as extinct. A leading figure in the hunt for the ivory-billed woodpecker said it was premature to call off the effort, after millions of dollars spent on searches and habitat preservation efforts.
Hilton-Taylor said there can be unintended but damaging consequences if extinction is declared prematurely. Federal officials said the extinctions declaration was driven by a desire to clear a backlog of recommended status changes for species that had not been acted upon for years. They said it would free up resources for on-the-ground conservation efforts for species that still have a chance for recovery.
Extinction Rebellion says the past three decades of conventional climate change campaigning has not been enough. At least 30 percent of tree species are at risk of extinction, while hundreds are on the brink of being wiped out. Think it's important to building an informed community?
