Taxonomy

Taxonomic note

Branta canadensis (del Hoyo and Collar 2014) was previously split as B. canadensis and B. hutchinsii following AOU (2004), and before then lumped as B. canadensis following Sibley and Monroe (1990, 1993).

Population justification: The global population is estimated at c. 5,000,000-6,200,000 individuals (Wetlands International 2015). The European population is estimated at 1,000-5,000 pairs, which equates to 2,000-10,000 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is increasing, although some populations may be stable and some are decreasing (Wetlands International 2015). This species has undergone a large and statistically significant increase over the last 40 years in North America (1500% increase over 40 years, equating to a 101% increase per decade; data for Branta canadensis and B. hutchinsii combined, from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). The European population is estimated to be increasing (BirdLife International 2015).
