Observations on the foraging behavior of Tricoloured Munia Lonchura malacca (Linnaeus, 1766) and its interaction with pearl millet fields in Villupuram District, Tamil Nadu, India

Study of foraging behaviour of Tricoloured Munia Lonchura malacca and its interaction in pearl millet crop fields was conducted in six villages of Tindivanam taluk, Villupuram district, Tamil Nadu from April to June 2020. A total of six flocks containing 1,640 birds of Tricoloured Munia were enumerated. The number of birds per flock varied from 60 to 800. They never split into small flocks and maintained the same flock size throughout the day. Tricoloured Munias used nine plant species for roosting. Twelve quadrats (0.3 ha) each of 5 m x 5 m size were laid in the pearl millet fields covering six villages. A total of 10,295 spikes were counted in these plots, and of these 3,785 spikes (36.7%) were found damaged by foraging munias. The maximum damage of 99.6% was observed in Thenputhur village. Along with Tricoloured Munia, five other granivorous birds, such as Baya Weaver Ploceus philippinus, Indian Silverbill Euodice malabarica, Common Babbler Turdoides caudata, Rose-ringed Parakeet Psittacula krameri, and White-rumped Munia Lonchura striata were also found foraging without any inter-specific competition. Farmers adopted various traditional bird repellent techniques such as beating utensils, throwing pebbles/soil on the crop, placing scarecrows, tying multi-coloured ribbons, and hanging bottles to chase the birds away.

Application Of Appropriate Technology For Automatic Bird Pest Removal And Automatic Fish Feed In The Minapadi System In Beutong Nagan Raya District

The purpose of this research-based service program is to apply the research results of the proposing team's research for community empowerment. The application of the research results was carried out on the program of application of appropriate technology for automatic fish feed and automatic bird repellent on the Minapadi jajar legowo system which is a system of planting rice with fish cultivation in one rice field area simultaneously and the jajar legowo planting system with a spacing of 25 cm . The technology used is automatic feeding and automatic bird repellent. Automatic feeding is done by using a mini water pump that has been modified with the help of a digital timer so that the feed automatically dispenses the feed at the time we specify, which is 3 times a day. The second technology is automatic bird repellent using extracts of herbal ingredients (jengkol) with the help of an automatic sprayer. This technology aims to increase the income of farmers with high productivity of rice yields and increase local fish production. The activity was carried out for 5 months in Beutong Nagan Raya District. The observed results include the feed that comes out of the automatic device as much as 15 gr/second, adjusted for the number and weight of fish. Meanwhile, the air pollution that comes out every 10 minutes is 5 units in a 25m2 plot.
