  1. Scare or otherwise deter birds from airports

    A replicated study in the UK (Brough & Bridgman 1980) found that fewer birds used grass on Royal Air Force airfields when it was allowed to grow long, compared to when it was kept short. In 1967-1968, ten English airfields were included, with data from 1972-1973 available for three more airfields (including one in Scotland and one in Wales). Grass was kept 15-20 cm high in some areas whilst others were maintained at 5-10 cm. The repellent effect of long grass was almost 100% for gulls Larus spp. and golden plover Pluvialis apricaria, and very good for northern lapwing Vanellus vanellus, Eurasian oystercatcher Haematopus ostralegus and crows (rook Corvus frugilegus, carrion crow C. corone, Eurasian jackdaw C. monedula).
