The EUNIS species component has very limited information about this species. The main focus of the EUNIS species component is to provide relevant information about the European species protected by Directives, Conventions and Agreements. The species assessed in the European Red Lists prepared by the IUCN for the European Commission are also included. See here what is Europe from a geographical point of view.

Distribution
Threat and EU population status
IUCN Red List status of threatened species
The IUCN Red List threat status assesses the risk of extinction.
EU population status
The status of the population at the EU level was evaluated at the species level; this was based on the reports delivered by Member States under Article 12 of the Birds Directive (see fact sheet below). The EU status assessment can cover several subspecies/subspecific population units. For more information, please consult the species fact sheet and link below.
