Every evening starting at around 1800h, the Asian Glossy Starlings (Aplonis panayensis), mostly juveniles, with some adults, will gather in my ceram palms (Rhopaloblaste ceramica) (above, below).
Once on the fronds of the palm, they move about the fronds, sometimes pecking noisily at the edges of the leaflets, probably to feed on the insects. They do not stay long in the palm, flying off to be replaced by others flying in.
Across the road, the two Mempat trees (Cratoxylum formosum) similarly see such gathering of starlings, but on a lesser scale (above, below). The starlings would fly in from the surrounding areas, attracted to the neighbour’s fountain for a bath and land on the branches to remain there for some time. Some would fly off to be replaced by others. The image above show a line of juveniles waiting their turn to enjoy their bath.
By around 1900-1930h, these Asian Glossy Starlings may suddenly fly off from the palms as well as the trees, triggered by a passing flock. The combined flock is most likely heading for some nearby large roadside trees, joining other birds like mynas for their night roost.
In the Mempat trees, the starlings remain quietly on the branches, flying to the glass partition of the house’s fountain or off to join others to be replaced by yet others. Around the same time the starlings leave the palms, these birds similarly leave the trees.
In these pre-roost gatherings, they do not generate much noise, unlike in the major roosting trees LINK.
