Another highly successful species, which has become a serious pest of fruit, is the Mossie or Cape Sparrow. The male mossie, with his black and white head and rufous mantle, is rather a handsome little bird; his wife lacks the head markings, being grey-brown with a pale eye-stripe.

Quotations
He had becoms full of Bay intelligence about mosquito repellent measures. Apart from the obvious—mossie coils, citronella candles, zappers, fine nets suspended over beds and Rid roll-on or spray—he decided to invest in bush gear from an army disposal store.
