Scientific Name: Cyanoptila cyanomelana
Malay Name: Sambar Biru-Putih Jepun
Chinese Name: 白腹蓝鹟
Breeds from Korea to Japan and winters to Southeast Asia
Polytypic. Subspecies are: intermedia, cyanomelana
Local Subspecies: intermedia
Size: 18 cm
Identification: Male has cobalt-blue upperparts, blackish head-sides, throat and breast with rest of underparts whitish. Female has rather uniform brownish upperparts and breast with contrasting white belly and vent, whitish throat-patch and all black bill. First-winter male resembles female but has blue wings, tail and back to uppertail-coverts. Both male and first-winter male has a small whitish patch at the base of the outer tail feathers which can be used to separate it from the very similar looking Zappey’s Flycatcher. This feature, however, may not be seen easily in the field as it could be obscured or covered by the primaries. Based on current knowledge, it is not possible to separate female from Zappey’s Flycatcher in the field.
Similar looking species: Zappey’s Flycatcher
Habitat: Forest, parks, gardens and wooded areas.
Behaviour/Ecology: Forages mainly at the mid-stratum and canopy levels for insects.
Local Status: Rare migrant
Conservation Status: Least Concern (IUCN 3.1)
Location: There were three photographic records of male bird in Singapore: Bukit Batok Nature Park in November 2009, the summit of Bukit Timah Nature Reserve in November 2010 and Dairy Farm Nature Park in February 2017. First-winter males and probable females had been sighted at Bukit Timah Nature Reserve, Dairy Farm Nature Park, Kent Ridge Park, Venus Drive, Bidadari, Singapore Botanic Gardens and Tuas South.
