Got another chance to re-visit sightings discovered a month ago ...
Due to the extreme distance before, what previously looked
like 2 black birds with woodpecker style of tree trunk
hanging turned out to be Drongos! Another lifer.
Their calls consists of a whistle followed by #$3%# ... somehow
hard to describe in words. A pair of them seem to focus
on a lone tree out in the open by the edge of an oil palm estate.
The fruiting tree seems to be the magnet or perhaps where their
nest is located as they constantly fly in and out.
