Not sure very well about this bird but as I see it you can find this bird all year round here at Kota Kinabalu especially on tall grasses or bushes along road sides or paddy fields. Happy birding.
It could be expensive for her to hire machine/modern style of harvesting her paddies. Economy this way as I see it because no much energy used harvesting traditionally though it may take longer time to sack in her paddies. What I may think here she will use hand gloves before she could finish her plots.
