How bird damage management is done in sunflower crop?

In sunflower farming, bird damage is a serious problem in sunflower cultivation. It can be managed by birds during the period from seed filling to harvesting. The rose- ruined parakeets are major bird pests of sunflower causing 10-40 % damage and in the isolated areas, it may cause damage more than 90%. Parrots invade the crop in flocks and inflict heavy damage and known to waste much more than what they eat. Bird scaring like tying of bright reflector ribbons above the crop should be used particularly in the morning and evening hours.
