Extinction in The Wild
The Socorro Dove is thought to have been extirpated mainly by feral cats, but high levels of understorey grazing by sheep may have limited the population. Human hunting might have temporarily brought down numbers, though little permanent settlement exists on Socorro. Cats were introduced apparently in the early 1970s. They do not seem to have been present in 1953.
The species reproduces no less willingly in captivity than other Zenaida doves, provided its different ecological needs are addressed. Most of the surviving birds are in zoos and other facilities in Germany and the USA. On October 30, 2006, the Socorro Dove was successfully bred at London Zoo. The bird was named "Arnie", after Arnold Schwarzenegger, with reference to his famous line "I'll be back" (on Socorro Island). However when Arnie was sexed he turned out to be a she. It is hoped that the descendants of Arnie and her relatives can someday soon be reintroduced into the wild. As of early 2006, it was being prepared to remove the sheep and to rid the island of cats. In the meantime, with the maintenance of the remaining birds, stock for reintroduction is being provided.

Famous quotes containing the words extinction and/or wild:
“I wish all men to be free. I wish the material prosperity of the already free which I feel sure the extinction of slavery would bring.”
—Abraham Lincoln (1809–1865)
“The colicky baby who becomes calm, the quiet infant who throws temper tantrums at two, the wild child at four who becomes serious and studious at six all seem to surprise their parents. It is difficult to let go of one’s image of a child, say goodbye to the child a parent knows, and get accustomed to this slightly new child inhabiting the known child’s body.”
—Ellen Galinsky (20th century)
