I was searching for birds at the back lane of Jalan Tan Tiong one Sunday evening.
There used to be a busy road that leads to the Police Flat, but now that building is now abandoned and the road became narrow overgrown with lalang and tall grass.
When I arrived, where was not a single bird around. I was not surprised because at 1:30pm, all the birds went into hiding from the noon heat.
Than I noticed a heat of insect activity on the second floor of that building. There you are, one big wasps nest and so many of that bugs flying around.
Slowly I inched forward and observed, none of the wasp tried to chased me. They just do their normal activity, building the nest. I braved myself and went closer to about 20 feet and got this few pictures.
