Diversionary feeding means providing alternative food, such as carrion, to hen harriers during the two to three months when they are breeding so that they kill fewer red grouse chicks.

Preliminary trials carried out at Langholm during 1998 and 1999 showed that the number of grouse chicks taken back to harrier nests could be reduced by up to 86%.However, there was no measurable increase in grouse stock during these years.

During the project we expect to provide all harrier pairs with carrion while they are breeding.
