Common bird index by type of species - EU aggregate

<p>The indicator is a multi-species composite index, which integrates the abundance and the diversity of a selection of common bird species associated with specific habitats. Rare species are excluded. Three groups of bird species are represented: common farmland species (39 species), common forest species (34 species) and all common bird species (168 species; including farmland and forest species). The indices are presented for EU-aggregates only and with smoothed values. The European Bird Census Council and its Pan-European Common Bird Monitoring Scheme programme delivers data from 26 Member States. MT is not covered.</p>
