Plant wild bird seed or cover mixture
A replicated, randomised, controlled study in September, November, December and February in 2004-2005 in seven grassland farms (87-96% grass) in western Scotland (Parish & Sotherton 2008) found that songbirds responded significantly more positively to wild bird cover crops in grassland compared to arable regions. Average songbird densities were two orders of magnitude greater in wild bird cover crops than conventional crops (average 51 birds/ha vs. 0.2). The average density of songbirds in wild bird cover in the grassland region was more than double that in wild bird cover in the arable region at the same time of year (average 61.3 and 29.0 birds / ha respectively). Average densities in grassland conventional crops were just 14% of that in the arable region. On each site, an average of 1.2 ha of wild bird cover and 10.3 ha of conventional crops was randomly sampled. Arable farm data from a previous study was used for comparison.
