Sterna dougallii (Roseate Tern)

European Red List of Birds

Supplementary Material

The European Union (EU27) Red List assessments were based principally on the official data reported by EU Member States to the European Commission under Article 12 of the Birds Directive in 2013-14. For the European Red List assessments, similar data were sourced from BirdLife Partners and other collaborating experts in other European countries and territories. For more information, see BirdLife International (2015).

THE IUCN RED LIST OF THREATENED SPECIES™ BirdLife International (2015) European Red List of Birds Trend maps

A symbol appears in each country where the species occurs: the shape and colour of the symbol represent the population trend in that country, and the size of the symbol corresponds to the proportion of the European population occurring in that country.

KEY

Ç Large increase (≥50%) È Large decrease (≥50%) Ç Moderate increase (20–49%) È Moderate decrease (20–49%) Ç Small increase (<20%) È Small decrease (<20%) ñ Increase of unknown magnitude ò Decrease of unknown magnitude

å Stable or fluctuating 0 Unknown ¢ Present (no population or trend data) Ð Extinct since 1980

Each symbol, with the exception of Present and Extinct, may occur in up to three different size classes, corresponding to the proportion of the European population occurring in that country. ñ Large: ≥10% of the European population ñ Medium: 1–9% of the European population ñ Small: <1% of the European population

The designation of geographical entities and the presentation of the material do not imply the expression of any opinion whatsoever on the part of IUCN or BirdLife International concerning the legal status of any country, territory or area, or of its authorities, or concerning the delimitation of its frontiers or boundaries.
