A mainly insectivorous bird, the paddyfield warbler feeds primarily on small flies, such as mayflies and caddisflies, but also consumes beetles, spiders and earthworms (2).
The breeding season of the paddyfield warbler extends from mid-May to mid-August. The nest, which is built by both sexes, is a tall, deep, cylindrical structure made from reeds and grasses. It is placed around the stems of aquatic or semi-aquatic vegetation, 20 to 100 centimetres above the water or land. The paddyfield warbler lays 3 to 6 eggs, which are incubated by the female for approximately 12 days. The chicks are fed by both parents (2).
In September, after breeding is over, the paddyfield warbler migrates south to spend winter in warmer climates, before returning to its breeding range in May (4).
