At dawn on a spring morning on the moorland edge above the Yorkshire Dales, groups of male black grouse gather on a lek — a traditional display ground that may have been used by the same species on the same patch of ground for decades. The males fan their lyre-shaped tails, erect the white undertail feathers into a powder-puff display, inflate their red wattles and advance on each other with bubbling, hissing calls and occasional brief physical confrontations.
The females watch from the edge of the lek, apparently indifferent but in fact selecting among the males on criteria that biologists have studied for decades without fully resolving. The whole performance is one of the most extraordinary wildlife spectacles available in upland Britain, and the Yorkshire Dales are one of the best places in England to see it.
The black grouse (Lyrurus tetrix) is a large game bird of moorland edge and upland woodland. Males (blackcocks) are unmistakable: glossy blue-black with a lyre-shaped tail and red wattle above the eye. Females (greyhens) are smaller and cryptically brown. The species feeds on a wide range of upland plants — heather, bilberry, cotton grass, birch catkins — and requires a mosaic of habitats: heather moorland for shelter, moorland edge and rough grassland for feeding, bog and rush for nesting.
The lek is the most visible behaviour of the black grouse and the most accessible to observers. Leks occur at dawn and, less commonly, at dusk from February to June. The same ground is used repeatedly; traditional leks may have been in continuous use for over a century.
Observing a lek requires care. The birds are sensitive to disturbance — a poorly positioned observer can cause the birds to flush and abandon the lek for the day. The RSPB and Black Grouse Recovery Project provide guidance on responsible viewing; organised wildlife watching groups use hides positioned at safe distances.
Black grouse have declined severely in England over the past century. The current English population is estimated at approximately 5,500 males — a significant reduction from historical levels. The Yorkshire Dales hold one of the larger English populations, concentrated in the moorland fringe habitats of the upper dales.
Conservation work through the Black Grouse Recovery Project — involving moorland management, predator control, and fencing of forestry and roads that are dangerous to lekking birds — has stabilised populations in several areas. The northern Dales, particularly Swaledale and the adjacent moors, are among the more reliably productive areas for finding the species.
