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.
