All was quiet until a sudden explosion of chatter and the very visible movement of the branches and leaves as the macaques jumped amongst the branches down towards the exposed mangrove mud below the trees.
The family soon showed themselves chasing something on the mud. The snake made headed straight for the water. It looked like a reticulated python about a metre long and it was sliding for its dear life away from the macaques. It managed to get into the water disappearing below the water surface not to be seen again.
Papa must have taken a very aggressive stance against the python due to the prescence of the baby and especially since the tree was amongst its most frequented spots near the main bridge.
