The teal is Britain's smallest dabbling duck and one of its most abundant wintering wildfowl, with wetland quality and freedom from disturbance determining welfare outcomes across its winter range.
Teal winter welfare is primarily determined by the availability of suitable shallow wetland habitat, the degree of human disturbance, and exposure to lead shot contamination. The progressive loss of shallow, vegetated wetland habitat across Britain means that remaining sites support higher densities of wintering wildfowl, increasing competition and disturbance. Legal requirements to use non-toxic shot for wildfowling have improved the lead shot welfare situation, but compliance monitoring is limited and historical sediment contamination persists. Wetland management that creates sheltered, undisturbed feeding habitat with shallow water and dense emergent vegetation directly benefits teal welfare across their winter range.
