Asia-Tropical Malesia (Borneo (SarawaknativeA))

Habitat

While C. minor inhabits the more open and cultivated districts [of Sarawak, Borneo], C. jefferyi, even at its lowest altitude, never quits the true forest. and the ranges of the two species never seem to overlap.B

Foraging

Snails, small frogs (observed on higher slopes of Kinabalu, Sarawak)B

Voice

Not nearly so clear as that of C.minor; but is still a feeble attempt at "Ton-ka-kis"B
