Hen Harrier The first breeding survey of hen harriers in Ireland was undertaken in 1989 -99, with more work in 2000 to fill in some remaining gaps in coverage. The survey aimed for complete coverage of the main breeding areas in the south midlands, south-west and some border areas of Counties Donegal and Monaghan, with randomly selected areas of 10 km square where breeding records were scarce or scattered.

Breeding of Hen Harriers • During summer months Hen Harriers breed in upland areas particularly in the south and west of Ireland ie. , Cork, Limerick and Kerry. These areas hold approximately a third of the breeding Irish Hen Harrier population. They make their nests during the spring and each produce between 1 and 6 eggs.

• The females are responsible for brooding eggs and hatching the chicks when they are young and for the first five weeks they spend most of their time on the nest. • The males provide nearly all of the food needed by both the adults and the chicks. They deliver the food in a brilliant aerial move called a “food pass”. As the male approaches the nest he calls to the female who rises up to meet him. The male either drops the food for the female to catch or delivers it to her directly. • The earliest broods of Hen Harriers may leave the nest during June but most chicks flee during July and are on their own by August. They then follow the adult birds to milder lowland areas for the winter.
