In New Zealand, the agricultural and horticultural industries view many introduced bird species as significant crop pests. In the arable sector, for example, introduced passerine species, such as house sparrows and greenfinches, cause substantial damage to high-value speciality crops, e.g., radish seed. Bird control techniques currently used by farmers such as scarers, shooting, repellents and pesticides are generally inadequate – they are either economically or environmentally unsustainable or simply ineffective. As very little is known about introduced bird populations and their ecology in New Zealand’s modified landscapes, it is difficult to determine the impact of different management strategies on their populations or how these strategies might be improved.
In this study, we investigated whether variation in bird abundance on arable farms during the breeding season could be explained by variation in habitat composition at different scales.
