The green iora (Aegithina viridissima) and the lesser green leafbird (Chloropsis cyanopogon) have nearly identical ranges, in
Thailand to the Malay Peninsula, Sumatra, and Borneo. They are listed as Near Threatened, as is the blue-masked leafbird (C. venusta), a Sumatran endemic. The Philippine leafbird (C. flavipennis) is Vulnerable. In addition to being restricted to threatened habitats, it has always been considered uncommon, in contrast to the other three IUCN listed species, which are considered locally common in parts of their range. Forest destruction has certainly caused losses of optimal habitat for a number of species, but as they are widespread, they are not considered globally threatened.
There is also concern about the cage bird trade. Several species of Chloropsis and fairy bluebirds were found to be popular among the markets of Singapore and Hong Kong in the 1990s. As of 2001, none of these species have been listed in any appendix of the Convention on International Trade in Endangered Species (CITES).
