Experiments comparing the use of kites and gas bangers to protect crops from woodpigeon damage

Woodpigeon damage to spring cabbage on two farms in different years was greatly reduced when a large kite was flown over the fields. Protection continued for over 3 months with no sign of habituation to the kite by pigeons. Woodpigeons avoided flying or settling within 250 m of the kite. Damage in fields with a gas banger exceeded that in fields with a kite, especially in severe winter weather. “Humming line” proved ineffectual in reducing damage. On these lowland farms it was necessary to launch the kite on most mornings, but if such launching can be carried out, kites can be effective in reducing damage by woodpigeons.
