Abstract
rger clutch sizes, and the apparent increase in predation levels, are discussed. Introduction Red grouse (Lagopus lagopus scoticus) are restricted to the heather (Calluna vulgaris) moorlands of the British Isles, an internationally scarce and valuable habitat type (Thompson et al. 1995). It is a bird of economic importance as a quarry species and has been the subject of several long-term studies investigating its' ecology, population dynamics and behaviour (e.g. Hudson 1986a, Hudson 1992, Hudson et al. 1998, Jenkins et al. 1963, 1967, Moss et al. 1975, Watson et al. 1994, Watson et al. 2000). Although periodic crashes in grouse numbers were recorded as far back as the early 19th Century (MacDonald 1883), it was not until the 1950s that the pattern of cyclic changes in grouse numbers were first investigated in detail (Mackenzie 1952). Since then there has been a series of detailed population studies followed by experimental investigations that have examined the possible cause of the c
