- Passenger pigeon. Once one of the most populous birds in North America, passenger pigeons could fly as fast as 60 mph, according to the Audubon Society.
- Golden toad. Last spotted in the forest in Monteverde, Costa Rica, in 1989, the disappearance of the golden toad has been attributed to global warming, Science magazine reports.
- Carolina parakeet. The vibrant feathers of the only species of parrot native to the eastern United States may have helped contribute to its demise. The Carolina Parakeet’s green, yellow, and red feathers were prized additions to women’s hats.
- Heath hen. Once common on the east coast of America, the heath hen could only be found on Martha’s Vineyard by the late nineteenth century. Wildfires, hunting, and habitat changes caused the heath hen’s remaining numbers to dwindle, the Vineyard Gazette reports.

Extinction is the death of all members of a species of plants, animals, or other organisms. One of the most dramatic examples of a modern extinction is the passenger pigeon. Until the early 1800s, billions of passenger pigeons darkened the skies of the United States in spectacular migratory flocks. Easy to trap or shoot, passenger pigeons became a ...
The passenger pigeon is one of many hundreds of extinctions that have been caused by human activities in the past few centuries, such as: 1. 1690 Dodo bird -- extinct from predation by introduced pigs and cats 2. 1768 Stellar’s sea cow -- extinct from hunting for fur and oil 3. 1870 Labrador duck -- extinct from human competition for mussels and ot...
Recent studies estimate about eight million species on Earth, of which at least 15,000 are threatened with extinction. It’s hard to pinpoint the exact extinction rate because many endangered species have not been identified or studied yet. A number of scientists grapple with improving methods for estimating extinction rates. Regardless, scientists ...
At five other times in the past, rates of extinction have soared. These are called mass extinctions,when huge numbers of species disappear in a relatively short period of time. Paleontologists know about these extinctions from remains of organisms with durable skeletons that fossilized. 1. End of the Cretaceous (66 million years ago): Extinction of...
At the end of the last ice age, 10,000 years ago, many North American animals went extinct, including mammoths, mastodons, and glyptodonts. While climate changes were a factor, paleontologists have evidence that overhunting by humans was also to blame. Early humans worked cooperatively to trap and slaughter large animals in pits. About the same tim...
The science of conservation biology focuses on managing ecosystems to prevent species from going extinct. Because we can’t protect everything, conservation efforts target particular species or habitats. Smithsonian scientist Dr. Brian Gratwicke is the “amphibian avenger” for his work to save populations of frogs from extinction. The Smithsonian is ...
Recent improvements in genetic engineering have raised questions about bringing extinct species back to life. Since Dolly the sheepwas cloned in 1996, scientists know it is possible to create an organism from the DNA in a single cell. Stored in museum collections throughout the world are specimens of extinct animals containing DNA. The idea of usin...
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Our best estimates suggest that extinction rates in the recent past have been running 100 or more times faster than in pre-human times 8 and 9, and that the pace of extinction has accelerated over the last few centuries (Figure 1 10 and 11). If this continues, the loss of species will soon amount to a large fraction of all species on the planet.
- 32 orchid species in Bangladesh—One of the first papers of 2020 to report any extinctions announced the probable loss of 17 percent of Bangladesh’s 187 known orchid species.
- Smooth handfish (Sympterichthys unipennis)—One of the few extinctions of 2020 that received much media attention, and it’s easy to see why. Handfish are an unusual group of species whose front fins look somewhat like human appendages, which they use to walk around the ocean floor.
- 65 North American plants—This past year researchers set out to determine how many plants in the continental United States had been lost. They catalogued 65, including five small trees, eight shrubs, 37 perennial herbs and 15 annual herbs.
- 22 frog species—The IUCN this year declared nearly two dozen long-unseen Central and South American frog species as “critically endangered (possibly extinct)”—victims of the amphibian-killing chytrid fungus.
Feb 3, 2023 · In September 2021, the U.S. Fish and Wildlife Service included the Guam flying fox in its proposal to delist 23 species from the endangered species list and declare them officially extinct.
