Ferruginous duck: Difference between revisions

The species is threatened by the degradation and destruction of its favoured habitats by anthropogenic causes which are very wide and varied including impoundment, drainage, pollution and mismanagement. The introduction of non-native species has also caused habitat degradation, e.g. the stocking of lakes with and accidental introduction of [[grass carp]] ''Ctenopharyngodon idella'' has caused reductions in plant and animal biomass available for the ducks to feed on. In addition, the increased threat of drought due to climate change may pose a threat to the species in the drier parts of its range. Increased disturbance by fishing boats and anglers among marginal vegetation could cause abandonment of the breeding sites or disrupt the timing of breeding particularly in populated areas, e.g. western Europe. Ferruginous ducks are also threatened by hunting and large numbers are shot on passage in the autumn and in the wintering areas. Although protected in most European countries illegal and accidental hunting persists. It is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' ([[AEWA]]) applies.<ref name = Birdlife/> Among recent local initiatives it should be mentioned inclusion of the breeding habitats of the species in Armenia into network of Emerald Sites protected by the Bern Convention <ref>http://www.abcc-am.org/ferruginous-pochard.html Ferruginous Pochard ('Aythya nyroca') at Armenian Bird Census Council</ref>
