Taxonomy

Taxonomic note
Riparia riparia and R. diluta (del Hoyo and Collar 2016) were previously lumped as R. riparia following AERC TAC (2003), AOU (1998 & supplements), Cramp et al. (1977-1994), Dowsett & Forbes-Watson (1993), SACC (2005 & updates), Sibley & Monroe (1990, 1993) and Stotz et al. (1996).

Population justification: The European population is estimated at 3,640,000-8,000,000 pairs, which equates to 7,280,000-16,000,000 mature individuals (BirdLife International 2015). Therefore it is likely that the global population falls in the band 10,000,000-500,000,000 mature individuals. National population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; c.100-10,000 breeding pairs and < c.50 wintering individuals in Japan, and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).

Trend justification: This species has undergone a small or statistically insignificant decrease over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). The European population trend is unknown (BirdLife International 2015).
