Grey herons (Ardea cinerea) are increasingly common in urban parks and gardens, raising questions about their welfare in human-modified environments and the ethics of supplementary feeding.
Urban herons face specific welfare challenges including collision with urban infrastructure, lead poisoning from fishing gear ingestion, and disturbance at urban heronries. Garden pond netting creates entanglement risks if improperly installed. Conversely, urban environments offer some welfare advantages: reduced agricultural persecution, diverse prey availability year-round, and reduced competition in early morning hours. Cold snaps that freeze fishing sites force urban herons to exploit higher-risk food sources.
