The Archive
of Lost Birds
A digital museum of species that no longer exist. At least 187 bird species are confirmed or suspected to have gone extinct since 1500 — most of them island birds, most because of hunting, introduced predators and the destruction of their habitats.
Figure: BirdLife International (2022), State of the World’s Birds. Extinction dates below are the last confirmed records or best estimates, and are labelled as such.

The causes
Most extinctions have more than one cause. Hunting, forest clearance and introduced animals — rats, cats, pigs, mongooses, monkeys — often acted together, and island birds that evolved without mammalian predators were especially vulnerable.
Counts refer only to the 29 extinctions in this atlas’s timeline, not to all bird extinctions.
