BIRDS

Birds are facing extinction due to factors such as habitat loss, hunting, and global warming, among other causes.

Here are 5 birds that disappeared forever:

Recently classified as a subspecies of the Guam Reed-warbler, it is said to become extinct in the 1960s due to the introduction of non-native plants, animals, and habitat degradation in Guam. 

The species went extinct in 1987 with the introduction of invasive plants, and the subsequent food shortages, combined with the impacts of avian pox and malaria, likely contributed to the species' extinction. 

Native to New Zealand’s North Island, the bird went extinct in 1970 due to habitat loss and predation by cats, rats, and humans. 

The species was last observed in 1928. It is said that a shipwreck brought black rats to Australia’s Lord Howe Island where the invasive rats quickly spread, preying on the Gerygone’s nests.

These extinct species vanished due to deforestation and likely avian malaria, an introduced disease spread by mosquitoes.
