The hen harrier brood management scheme divides conservation opinion, with proponents arguing it increases harrier numbers while critics contend it subsidises driven grouse shooting at harriers expense.
The welfare dimensions of the brood management debate are complex. Captive rearing of wild-born raptor chicks carries welfare risks including imprinting, disease exposure and the stress of captivity. Released birds face the same persecution risks that caused population decline in the first place. Critics argue that brood management fails to address the underlying driver of hen harrier persecution — the economic incentives of driven grouse shooting. A welfare-first approach would prioritise ending illegal killing over managing harrier reproduction to accommodate a land use that drives persecution.
