Question

Name any four recent extinct organisms as per IUCN Red list.

Answer 1

Hint: The IUCN Red List is used by federal authorities, wildlife departments, conservation related non-governmental organizations (NGOs), natural resource planners, professional institutions, students and the business community.

Complete answer:
Founded in 1964, the International Union for the Conservation of Nature's Red List of Endangered Species has been the world's most authoritative source of knowledge on the global conservation status of wildlife, fungi and plant organisms. The IUCN Red List is much more than a list of species and their status, it is an important instrument for educating and catalyzing biodiversity conservation and policy reform that is essential to protecting the natural resources that we need to live. It includes information on the range, population size, environment and biodiversity, use or trade, risks and management measures that can help inform the appropriate conservation decisions.

According to the IUCN Red list, the recent four extinct organisms are:
1) Black-faced Honeycreeper: Black-faced honeycreeper is an endangered species of seasonal bird that was endemic to Maui Island in Hawaii.
2) Madeiran large white butterfly: The Madeiran large white has been named the first butterfly in Europe to be endangered as a result of the human effects. The Madeiran large white experienced a terminal decline as a result of the loss of habitats to the development of new businesses and houses, including holiday homes.
3) Pyrenean ibex: According to the IUCN, the Walia ibex is in risk, with just around 500 of its type left. One animal, the Pyrenean ibex was considered extinct in 2000. It might not be gone forever.
4) West African black rhinoceros: West African black rhinoceros was a black rhinoceros subspecies considered extinct in 2011 by the IUCN.

Note: Extinction is the termination of a type of organism or a group of organisms, typically a species. The time of extinction is usually believed to be the death of the last member of the species.
