Borneo Birds

The Square-tailed Drongo-cuckoo Surniculus lugubris has got to have one of the most recognizable calls in the lowland forest of Borneo.  The first loud pi is followed, evenly timed, by a series of ascending pi.  As is the case with other cuckoos, such calls can be heard throughout the day and sometimes at night.  Spotting it may be a bit more difficult.
