Results No significant difference was found in the number of Swallows on organic and conventional farms. Nor was there any significant difference in food availability or farmer attitude between the two types of holding. On conventional farms there were significantly more buildings qualifying as preferential Swallow breeding sites, but this did not result in more Swallows on these holdings. Conclusions Our results show that the adopted regime of dairy farm ma
