Farmland birds including skylarks, yellowhammers, and grey partridges have experienced catastrophic declines driven by agricultural intensification, representing a welfare emergency at population scale.
Farmland bird population declines represent welfare harm at the level of millions of individual animals losing the habitat conditions they need for successful reproduction and survival. Pairs failing to raise chicks due to inadequate nesting habitat experience reproductive failure repeatedly. Individuals failing to find winter food starve. The scale of decline means this is one of the largest ongoing wildlife welfare crises in the UK, yet it receives far less attention than individual animal welfare cases.
