Common Pochard Welfare and Diving Duck Decline

The common pochard is a diving duck that has suffered a dramatic and poorly understood population crash across Europe, with UK wintering numbers falling by over 70% since the 1980s in one of the most concerning waterbird declines.

Key Facts

UK wintering pochard numbers fell from around 75,000 in the 1990s to under 38,000 by 2015
The species breeds across northern and central Europe; fewer than 600 pairs now breed in the UK
Males have a distinctive chestnut head, black breast, and pale grey body
Pochards dive for aquatic plants, molluscs, and invertebrates in water up to 3m deep
The cause of the dramatic population decline remains poorly understood despite intensive research

Welfare Considerations

Pochard welfare is threatened by declines in aquatic vegetation and invertebrate communities in European freshwater lakes. Lead poisoning from ingested fishing weights is documented in diving ducks. Botulism outbreaks on eutrophic lakes kill large numbers of pochards during summer. The species is hunted legally in some European countries, adding additional pressure to an already declining population. Urgent research into decline causes is needed to identify targeted welfare interventions.

What You Can Do

Support BTO and RSPB research into pochard population decline causes
Advocate for lead fishing weight ban across Europe to reduce diving duck poisoning
Contribute pochard count data to WeBS surveys to maintain long-term population records
Back lake eutrophication reduction programs that may improve pochard food availability
Engage with European shooting policy to advocate for hunting moratoriums on declining species
