James Heng was at Lower Peirce in late January 2008 when he came across a sarcaca tree, possibly yellow saraca (Saraca thaipingensis), in full bloom:
“There are about five pairs of Purple Throated Sunbirds (Nectariniua sperata) feeding voraciously on the flowers of a tree at Lower Pierce Reservoir (above).
“That flowering saraca tree is a magnet for the birds of the Nectariniidae family. At one point in time this afternoon, there were four species of sunbirds – Olive Backed (Cinnyris jugularis), Brown-throated (Anthreptes malacensis), Crimson (A. siparaja) and Purple Throated, feeding together on the flowers’ nectar at the same time.
“A pair of Scarlet-Backed Flowerpeckers (Dicaeum cruentatum) also decided to join in the buffet. They plucked off and ate the saraca small green fruits.
“The feeding frenzy rose several notches just before and immediately after each of the intermittent episodes of rain.”
There are a few species of saraca trees planted in Singapore, originating from nearby Malaysia. The image above shows the yellow saraca with its attractive purple young leaves hanging like tassels from the ends of branches. It would take a few days before these leaves stiffen up and turn green. The tree is just beginning to flower. When in full flowering, the large bunches of yellow to orange-red flowers appear in dense clusters from the main branches and trunk. The flowers are faintly fragrant, each with a crimson eye-spot that darkens to blood-red.
The tree attracts many species of birds that visit for the flower nectar and fruits.
