The White-throated kingfisher, Halcyon smyrnensis, is widely distributed from the Middle East throughout most of Southeast Asia except for the island of Borneo, where it has been recorded as an occasional visitor but not yet as a resident breeder. During standard biodiversity monitoring activities, adult birds were regularly observed at PT Suria Sawit Sejati (PTSSS) estates. Regular monitoring of adult birds commenced and the location of observations was mapped. Records of birds in pairs suggested that these were indeed pairs and subsequent monitoring confirmed this. Here we present comprehensive evidence of the White-throated kingfisher as a resident breeder in Central Kalimantan, Indonesian Borneo.
