AB Insular ecosystems have been subjected tosevere hardship during the last millennia. Large numbers ofinsular bird species have undergone local disappearancesand full extinctions, and a high number of insular birds arecurrently categorised as endangered species. In most ofthese cases, extinction—or endangerment—is in directrelation to the arrival of ‘aboriginal’ and/or imperialistwaves of human settlement. Insular bird extinction eventshave been documented to have occurred at times corresponding to aboriginal settlement at many archipelagosand isolated islands, such as the Hawaiian Islands, NewZealand, the West Indies or the tropical Pacific Islands.However, no bird extinctions could be attributed to thefirst settlers of the Canary Islands—until now. The firstaccelerator mass spectrometer radiocarbon (14C) dating ofcollagen from a bone of the Dune Shearwater Puffinusholeae (3395 ± 30 year BP), an extinct bird from theCanary Islands, indicates a late Holocene extinction event.This relatively recent date, together with some features ofthis bird (large body size, breeding areas situated at veryaccessible places) and the absence of its bones from the entire archaeological record suggests that the extinctionoccurred close to the time that the first human settlementoccurred on the islands.
