In the absence of any early flood warning system, villagers in Assam are banking on abnormal animal behaviour to predict and survive sudden inundation of their houses, say researchers. When insects like locust, grasshopper etc come out from their hideouts and fly randomly and enter houses, the situation suggests a sudden change in the weather condition, more occasionally flood with heavy rain, the scientists found. Similarly, when ants shift their shelter to higher places with their eggs and food stuff, it indicates a definite forthcoming flood.
When a fox howls irritably at a higher place it indicates a forthcoming prolonged drier season but when it howls from a low-lying location it indicates a probability of high flood.
The cry of doves and two particular species of birds are also warning signs, according to a report by Ludhiana-based Central Institute of Post Harvest Engineering and Technology scientist Armaan U Muzaddadi.
