List of the species comprising the bird community examined in this study and their habitat characteristics.

<p>Habitat specialization (farmland specialist vs. generalist) is given for each species, and specialization index for grasslands (SSIg) and main habitat of specialization are given for each farmland specialist. ‘SSIg’ is the habitat specialization index of each farmland species; the higher it is the more specialized is the species for grasslands. ‘Main habitat’ corresponds to the main habitat of farmland species, determined on the basis of SSIg (see the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117850#sec007" target="_blank">statistical methods</a> section for more details).</p><p>List of the species comprising the bird community examined in this study and their habitat characteristics.
