Of the 3 fantails found in Borneo, I really think the Spotted Fantail Rhipidura perlata is the better looking!  But looks aside, there is also differences in behaviour.  I notice that the Spotted does not fan its tail as often as the other fantails and it sits in a more upright position.   Otherwise, like the others, it is an active insectivore, pursuing its prey from all angles.

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.
