 For instance, the endangered South Island takahē's wild population dropped by a third between 2006 and 2007, after a stoat plague triggered by the 2005–06 mast wiped out more than half the takahē in untrapped areas.Tuberculosis has been recorded in stoats inhabiting the former Soviet Union and New Zealand.They are largely resistant to tularemia, but are reputed to suffer from canine distemper in captivity.
