Rats, mice, fruit bats and crows have been termed as 'vermin' for destroying crops and now the Grey-headed swamphen or 'Neela Kozhi', as it is called in Kerala, may also be added to that list if the farmers of pokkali rice have anything to say on it. The grey-headed swamphens are usually found in uncultivated paddy fields or swampy areas of wetlands where they roost and breed.
