Europe is home to more than 500 wild bird species. But at least 32 % of the EU's bird species are currently not in a good conservation status. The Birds Directive aims to protect all of the 500 wild bird species naturally occurring in the European Union. +
194 species and sub-species are particularly threatened. Member States must designate Special Protection Areas (SPAs) for their survival and all migratory bird species. +
82 bird species can be hunted. However, the hunting periods are limited and hunting is forbidden when birds are at their most vulnerable: during their return migration to nesting areas, reproduction and the raising of their chicks. +
Overall, activities that directly threaten birds, such as their deliberate killing, capture or trade, or the destruction of their nests, are banned. With certain restrictions, Member States can allow some of these activities for 26 species listed here. +
The directive provides for the sustainable management of hunting but Member States must outlaw all forms of non-selective and large scale killing of birds, especially the methods listed in this annex. +
The directive promotes research to underpin the protection, management and use of all species of birds covered by the Directive, which are listed in this annex. +
Mouth parts designed to grasp and macerate food before swallowing (e.g. most vertebrates) +
Mouth parts designed to pierce outside of food or prey and feed on internal fluids or tissues +
Organisms that live in 'I' or 'J' shaped burrows open at only one end where water is drawn through or diffuses out of the sediment e.g. ''Arenicola marina'' (adapted from Kristensen ''et al.'', 2012). +
Build up or accumulation of sediment. +
Maerl; twig-like unattached (free-living) calcareous red algae, often a mixture of species and including species which form a spiky cover on loose small stones - 'hedgehog stones'. +
A measurement of the size of the organism. Note - the measurement used to express body size varies within taxonomic groups. For example, some disciplines measure diameter, others carapace length, total body length or wing span. Also body size can vary with gender and life stage. +
Maximum recorded linear body length (in millimetres) excluding appendages. +
Species that have been intercepted at borders as a result of detection procedures. +
The second the two free-swimming larval forms in the asteroids, characterized by the appearance of three adhesive arms at the anterior end (Ruppert & Barnes, 1994; Stachowitsch, 1992). +
