Patterns of spatial distribution and migration phenology of common pochards Aythya ferina in the Western Palearctic: a ring‐recoveries analysis

“…As a recent study on pink‐footed geese Anser brachyrhynchus suggests, the solution for defining management units may reside in the compilation of different sources of data (ring recoveries/CMR, population genetics, isotopes, Madsen et al 2014). Concerning common pochard, currently available data include genetic markers (Sruoga et al 2009, Liu et al 2011), isotopes (Caizergues et al 2016), and ring recoveries (Hofer et al 2006, Keller et al 2009, Viksne et al 2010, Gourlay‐Larour et al 2012, 2013); all support extensive movements among populations in the Western Palearctic. Moreover, isotopes and ring‐recoveries also suggest that the bulk of the population wintering in western Europe may originate from the northern and eastern parts of the species' range (Scandinavia, Kazakhstan, western parts of the Ural mountains) (Caizergues et al 2016, present study).…”

Average (± SE) autumn and winter recovery locations of pochards ringed in the former USSR and Latvia, and later recovered in western Europe in countries/months where hunting was allowed over the entire study period.…”
