General Biology

A rare winter visitor and passage migrant. Birds arrive in Singapore in late September, peaking in October. Singletons have been recorded in subsequent months.

Earliest date recorded: 23 Sep; Latest date recorded: 16 Jun

Found singly in mangrove forests, scrubland and wooded gardens, along banks of small streams. Occasionally found far from water. It has a very feeble whistle, uttered on the wing. It's flight is swift and twisting. At rest, it sits very erect, with the bill pointing upwards or forwards, not hunched up like Common Kingfisher.

One bird found in November had arrested its primary feather replacement: P1=old, P2-4=new, P5-7=old, P8=new, P9-10=old. Another bird found in December 4, 2011 also had an arrested primary moult: P1-2=new, P3-6=old, P7-8=new, P9-10=old.

Diet

Feeds partly on fish and crustaceans like prawns, also frogs. It is said to also take spiders. It has been seen flying over the surface of water and snapping up grasshoppers, winged ants and mayflies floating downstreams (Robinson, 1928). After feeding , it casts a pellet consisting of the hard, undigested bones and excoskeletons of its prey that have been compacted in the gizzard.

Records

An adult ringed by the Singapore Branch Bird Study Group on 17 Nov 1974 is the first recent record after World War II. One bird was brought alive to a veterinary surgeon on 2 Oct 1981 (Hails, 1988). There were few subsequent records. This species is probably under-recorded as 2–3 birds were salvaged every winter (Wang, L. K., unpublished data).
