Brent geese are long-distance migrants that breed in the Arctic and winter on UK coasts. Their welfare spans multiple continents and is affected by conditions at breeding, staging, and wintering grounds.
Brent goose welfare is shaped by conditions across three continents. Poor body condition at migration departure from Siberia - caused by late snow cover preventing feeding during breeding - translates directly into migration mortality. Disturbance on estuarine wintering grounds forces birds to expend energy flying repeatedly, reducing the fat reserves needed for spring migration. Agricultural conflict when birds move onto grassland leads to legal and sometimes illegal disturbance. The interconnectedness of brent goose welfare across continents makes it a powerful example of why international migratory species conservation is also an animal welfare issue.
