Taxonomic note
L. michahellis and L. armenicus (del Hoyo and Collar 2014) were previously lumped as L. michahellis following a review by the BirdLife Taxonomic Working Group. Prior to that, L. armenicus had been split and L. cachinnans (del Hoyo and Collar 2014) had been lumped with L. michahellis as L. cachinnans following Sibley and Monroe (1990, 1993).

Population justification: The global population size is unknown owing to recent taxonomic splits. The European population is estimated at 409,000-534,000 pairs, which equates to 819,000-1,070,000 mature individuals (BirdLife International 2015).
Trend justification: The overall population trend is increasing, although some populations have stable or unknown trends (Wetlands International 2015). The European population is estimated to be increasing (BirdLife International 2015).
