as well as in more open areas with scattered trees. It forages in the tree canopy for insect
s sometimes joining mixed-species foraging flocks. Migrant birds can often be seen in large flocks.
The status of the species is considered to be secure and is considered as a "least concern" species by the IUCN. Populations of the species on the Amami Island was found to have increased from 1985-2001.
