 Estimated numbers include ranges of 100 to 10,000 breeding pairs and 50 to 1,000 migrating individuals respectively in China, Korea, Japan, and Taiwan; total population size is thought to be somewhere between a few thousand and a few tens of thousands of individuals.Although researchers estimate that the largest number of birds survive in China, no concrete study has been done.However, a worldwide trend of decline in the fairy pitta is clear enough to lead to a classification of the species as Vulnerable on the IUCN Red List of Threatened Species and as Endangered in CITES Appendix II.
