Taxonomy

Taxonomic note
The BirdLife Taxonomic Working Group is aware that phylogenetic analyses have been published which have proposed generic rearrangements which may affect this species, but prefers to wait until work by other taxonomists reveals how these changes affect the entire groups involved.

Population justification: The global population is estimated to number c.1,600,000-3,600,000 individuals (Wetlands International 2015). The European population is estimated at 316,000-605,000 breeding pairs (BirdLife International 2015).

Trend justification: The overall population trend is unclear. Some populations may be stable, while others have unknown trends (Wetlands International 2015). In North America, the species has undergone a large and statistically significant decrease over the last 40 years (-70.4% decline over 40 years, equating to a -26.2% decline per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). In Europe, the population is estimated to be increasing (BirdLife International 2015).
